I found it @Walmarthttps://www.walmart.com/ip/Shoreline-Marine-Liquid-Electrical-Tape/28429509

That might be an old link, but they say they have it. I probably bought it from Amazon, but you're correct, it's not there anymore. Walmart can be really funky to order online from because they use vendors and rarely check up on them. Unlike Amazon, if you go through a vendor and the deal sours, Walmart will tell you your beef is with the vendor. We're not talkin' a lot of money here, so I'd take the chance if you can order it through Walmart.

I was trying to get you to stay away from Star Brite(in the yellow can) and another brand I dislike called 'Brush-On' by Bluemagic. I haven't tried all of them out there, but at least four major brands. The Shoreline Marine product was a head taller than the rest.

If you went to an industrial site that catered to people manufacturing boats, I bet you'd find a good product maybe even more durable than the Shoreline product.

Yeah I found that Walmart entry too, but it's not orderable for me from anywhere, Walmart, 3rd party, not available in any store within hundreds of miles. I'd say it's discontinued.

It's weird to me that the Shoreline stuff would be that much different, since it's made by Star Brite.

West Marine makes a liquid electrical tape. There's also MDR, and Seachoice
 
Figured I'd update my struggles with my 52 several pages back. It was recommended that I bend needle lever flat with carb body on diaphragm end. I tried that with no change to how it ran. Still wouldn't idle and tuning lo screw seemed to have no effect. I then realized lever that came in carb kit looks ever so slightly different than original lever in saw. I switched them and the saw runs great now. I'm sure with tweaking on it I could have got it right, but original one was already adjusted correctly. Biggest thing I could see was one in kit was bent slightly down on the needle end. I think this was likely limiting needle travel. So it kept starving for fuel at idle/low end.

Anyways excited to finally put this one in some wood.20221129_230050.jpg
 
Those dial-a-hole punch tools do work, but I wanted more variety of holes than that offered for larger engine gaskets. Plus, the one I bought was a POS. I'm sure there are probably still good ones out there, but I bet it would exceed the price of the full HF punch set.

I agree with Robin on the sequence; I cut the small holes first, check against the gasket.....then the center hole and finally the outline of the gasket. I do the small holes first and check because if you do them at the end you have all the time into that gasket and have to pitch it if you made a mistake. Keep checking your gasket against the original as you proceed along. You can also punch your small holes 'through' the old gasket....just take care you don't damage your 'template'.....lol.

I was lucky enough to score an old Spearhead NO. 750 "Handy Gasket Cutter" made by Zimmerman Packing way back in the day. The set was new and never used, a metal box with a metal hinge....lol. . Even has a pivot piece you can drive into a wooden surface board or a Delrin board to cut your gasket on. I had to read the instruction a few times to understand all the ins & outs, but it's a pretty great tool.

Kevin
Yeah you can see the difference between the one in the fist pic I posted and the the pic of the one I use.......solid steel opposed to pressed tin. There is no give to the tool when punching. I think I gave less than $20.00 for it but that was a while ago. It works great and better on slightly rubberized material than straight paper....though it's easy to do a good job with either as you can see exactly where the punch point is while holding a slight strain on the tool.......pretty hard to get out of control with it, plus the hole is always square to the material.

The main reason I do the small holes first is doing it that way you don't run the risk of tearing the gasket material when the hole is close to the edge of the gasket.
 
On another note, looking for some help on my 451ev. Don't have a lot of time to deal with it so listed for sale locally but haven't had much interest. It's missing one of the starter pawl springs which has limited me from trying to measure compression and see if it'll at least fire on premix. Figure I might as well continue tinkering with it and see if i can at least get it running. Can someone help me with a Jonsereds part number for the spring so I can try and find one?

Thanks

Great!! Glad you got it figured out!!

The part # is 504 217 302 for the 451 and 450 too.
 
Thank you very much!

I pulled my local ad and figure I might as well try and get saw running. If heated handles work it would be nice cutting in the wood pile this coming winter. Maybe it'll be a keeper.
You get used to heated handles quick in our climate!!!!!!

I know I'm my recent spending spree on 451 parts I've come across eBay listings for the flywheel with pawls. I'll see if I can find the listing and I'll send it over.
 
Yamabond is OK if you have to, but preferably not. NAPA and I imagine others have a spray product made to remove gaskets/residue....try that if patience and a razor don't work. Yes, everything needs to be clean to get a good seal and no air leaks. Don't start out with an air leak and a new P&C.

Your impulse is definitely on the bottom of the carb/cylinder flange. If you feel confident, I'd make both gaskets. If you're determined to use the old carb-to-manifold gasket, at least soak it in water for a while and let it dry. Sometimes that rejuvenates their depressions. Anyone making gaskets should have a set of hole punches(Habor Freight, but you have to sharpen them) and a little gasket cutter that cuts circles. The outline itself of the gasket can be cut with a razor knife etc. I actually enjoy making gaskets.....it's therapeutic. Especially paper....rubber can be tedious because it stretches sometimes while you're trying to cut it.

Here's a pic of the product I use for failing wire insulation....I think I got it on Amazon from a vendor. I would do two coats; letting it completely dry after the first. Don't goober it on; better to use thin coats. Epoxy will work if it's close to the module, but that makes it stiff and from there downstream the insulation will still try to de-laminate.

If for example, you have a bad place where a case part or whatever is pushing/rubbing against the wires.....I would use two coats of liquid insulation and then a piece of heat shrink over that. If you can't get the heat shrink over the terminal end of the wire......I'd split it longways(ID of the heat shrink the same as the wire OD), with a razor knife, and put it on with more liquid insulation. This way you're making a 'bumper' for the wear point. Close-up pics please of the damage.

This all started when Euro manufacturers began using soy wiring harnesses and soy insulation. They thought they were being eco-conscious. What it did, in reality, was make old insulation decompose.

Kevin
Is this clean enough or should I keep trying to remove the few spots left on the brass? Went at it with permatex gasket remover and a brass brush to get the thicker stuff, then followed that up with a Dremel and a nylon brush for the smaller residue.IMG20221130142559.jpgIMG20221130142637.jpg
 
Not familiar with that model to work on....BUT those plug leads aren't all screwed on. I ruined a coil on an 80 by trying to unscrew the coil lead....it was molded in somehow. Not saying yours is, but you should see the little screw threads inside the coil if it does work that way.

You guys gotta post pics with questions like these...;)

Kevin
Here are the areas of concern on my coil and module IMG20221130152056.jpg

It's probably not as bad as I'm thinking it is, but I want to avoid future problems.

I picked up some CRC QD Electronic Cleaner, safe to use on these parts?

That looks pretty normal on that era Jonsereds saws......I've seen much worse. Yep clean it good and put the liquid tape to it. As Kevin says the Star Brite may not be optimum......it is pretty thin and not really designed to replace insulation. It is generally used to merely coat screw type marine connections on switches etc. just to keep moisture/corrosion at bay. However if you have time and patience you can build it up fairly thick with numerous coats

@Cantdog and @Real1shepherd, any experience with the liquid tape offerings from MDR, West Marine or Seachoice?

No I do not......but from my experience West Marine products are very good. I use West System epoxies and various additives frequently......not on saws but woodworking and fiberglass work.

Of course you want to use the best stuff but what you are trying to accomplish not allowing those two bare wires to touch each other or go to ground......so whatever you use to achieve that end is what is necessary.

Looking at the can, it says nothing of Star Brite....just a 'Big Game International Brand'. And it says made in the USA in a couple of places.....so not sure why it was recalled in Canada or why that makes any difference.

As I said, I haven't tried them all, but I began to see a pattern; poor adhesion, drying unevenly, too thin and not very durable against even the modicum of friction. Then I bought the Shoreline product and it was much better. I even threw away that yellow can I had of Star Brite.....I really consider it an inferior product.

This looks promising from a marine/RV seller, but I have no experience with it:https://www.ebay.com/itm/303578425301?epid=1022071268&hash=item46aeaf27d5:g:GHUAAOSwyi1a~xjr&amdata=enc:AQAHAAAAwNjZR+YB6pUnanbsD1BgDoenK5YjKq8yYdknk25adq9R/UFE4GMlcdYxnBaVKd6XxaruwtCHSFaaOvKQn38s5HXA9xvmQewNLkOZKw2tTaWyJY3FufzUlSyQ0BcvlkJ0vPkam9FsIRDHUAEz1HdRzUYOLMuNjnY3D16qpNOco7Mbrc6vwo2lghZ0kHBHpJqutcMS8DJmE0bempEYzwKg1kD2+j4IXS+JYE4vfh/mT/K383YlFNY5u38mn+TwH52nHA==|tkp:Bk9SR_jK8a-ZYQ

Nylon brush and a chem that doesn't attack the manifold material. You know gasoline won't hurt it.....lol! Looking good though. Technically, your seal comes from all those ridges around the brass.....but if doesn't damage anything, I'd keep going....you're almost there.

Cleaning the wires and related stuff with the CRC product should be fine. I use it a lot.:cheers:

I had a gut feeling it was that fork....especially when you said it was bent up. These days, I'm really leary of AM carb kits.....didn't used to be. I go for the authentic Tilly kits......seem to be still out there. The last thing you wanna be doing in a restore is trying to hunt the fault down of a little misshapen part like that which is supposed to be new.
