Thats a sharp looking saw!

 

[vinnywv]

Thankyou. It turned out just fine to me also. It was fun. We talk alot about interchangeable mac parts. This was no exception.

Oh. I wasn't going to do that. I don't have the gasket.
If I can get this saw going I would like to repaint it one day so would leave such things until then.

I was going to put the piston, crank and block together first. Just trying to get some bits of old carb gasket off first. The small bearing comes off easily, perhaps I should put some grease on the inside? Then a little oil on the piston/rings as it goes in then RTV the block halves and bolts.

Did you buy my gasket set ?
I'm gonna be putting up a special set for the 10-10
The best sealer from tests is Hondabond

I did - one of them is going in this saw (which we think is a PM60).

PM me mate! I'll send you some goodies

Thanks! But remember I'm on the other side of the world!

I use a bit of greese to hold the rod needle bearings in place while I assemble. Some two stroke oil on the rings. Mark H has turned me on to Dirko HT to seal the blocks. I have to agree its good stuff.

I've put together a couple saws with Yamabond 4 , no failures as of yet. That being said plenty of McCulloch saws are put together with regular old clear sealer from the old days.

This is what uncle has used for decades. I got saws here with it on them for 30 years he built. Still going. I just researched the Dirko after Mark mentioned it. Its being used OEM for Stihl, I just wanted better, best, bestest lol. Sometimes I forget the if it ain't broke don't fix it saying.

On a side note...If you post about using Dirko HT on Facebook a couple guys will scream at you that the saw will blow up. apparently if its red is terrible stuff. Non red good, red bad. thats all I could get from the two guys after explaining about Dirko. I added this note because they reminded me of a saying James and I started a few years back. "Some people are to stupid to own chainsaws". Why I love the forum above all other places. None of the kinda BS here. Just knowledge, advice, collaboration , and a desire to help and learn. All good stuff.

Maybe I should just fly the core of the forum in here to help finish it for me!

isn't there something about baking coils that can bring them back to functioning?

Baking a coil is:
Not good for a permanent reliable repair.

The coil (magneto) has moisture inside and this creates a path for arc over internally and the arc over will usually leave a carbon trail.
You are just doing a temporary fix. (Rube Goldberg category)

Kinda in same category as peeing into the wind.

Virginia isn't too far from me , nice change of pace I've been building stairs this week.

I got my 3rd PM55 yesterday,this one for $50.I checked it for spark & it was a spark here & there,probably dirty/corroded points.It also has low compression - 90 psi.I'm going to pull the carb off today to have a look at the intake side of P&C.

Howdy!

I got my 10-10 carburetor taken apart and somebody has been in here before me. There were flip flopped gaskets and I found some damage to an adjustment pin.

I first cleaned the carb without full disassembly. The saw will run but bogs really badly. I have to adjust the low speed two rotations for it to run rich and then I can't get it to idle. Clearly something is wrong.

Here is picture of the two adjustment screws. I am assuming the high speed pin should have a nice clean end and not a partial hole and unevenly ground end?

Is this a part i can find?

Should there be a mesh screen in the larger welch plug hole?

I do have one in the kit, but the carb was missing this part.

I also found that under the tiny snap ring, the old screen and replacement were still in the carb.

Thanks for the help!

both of those holes should have welch plugs. the one with the brass part should have a rubber disc at the bottom that looks missing. it is the check valve. it is def missing the screen and circlip. a carb kit will have new welch plugs but for the check valve you need this kit.

a few weeks ago or less, when I finished my 10-10S refurb I posted a short (like 10 seconds) video on YouTube so I could post it here. I was just on YouTube and noticed that it has had over 4,700 views. that's just crazy.

I removed the welch plugs, snap ring, and two screens. There was no rubber disc. The Brass part in the new kit looks different. Mine has a hole in the middle. Should the brass part be removed? It seems like it is seated pretty well.

Edit: Does the brass part in the kit already have the screen and snap ring installed?

That would be pretty cool
