FarmerTec Huztl MS660 Updated Build Kit - Build Thread

[dmitriy]

Was that squish with base gasket? Mine was .037 with out gasket. Compression is 150.

Mine was 0.020 WITH the metal base gasket (one with indents and wings)

I think I measured right- inserted solder through decompression and spark plug holes at the same time and cranked it over then measured the solder Squish area...???

You must have gotten a better cylinder than I did. Did it have a name on it? I checked my squish with solder in the spark plug hole parallel to the piston pin. Then mg suggested doing it with 4 pieces at once on top on the piston held in place with grease.
How much compression do you have with that good of a squish?

Not sure on the cylinder name will have to look around on it (it was in a Farmertec box but that doesn't mean anything). I did my squish opposite sides one through spark plug one through decompression valve (above intake / exhaust ports) though to be thorough I guess I could gone with the 4 way...
I just did a crude (no plug instead of decomp valve, tester threads were a bit long so I had to use plumbing tape) compression test and got around 130psi. Seems a touch low no? Not sure if I can give it a strong enough yank this morning.

I have only run the saw/rings in for about 5 mins max & NOT at all close to max RPM (carb needs adjustment to make sure everything is correct and the Chinese wrist pin / bearings need to be replaced with OEM) so I wonder if it's effecting it?

This is my second saw ever, the previous one is a Mac 3216 I resurrected, but I have done a ton of dirt bikes so the engine thing is not that foreign.

Mine is completely kit parts except fur champion spark plug and Husqvarna decomp valve. My cylinder had no name but in farmertec box. My compression was 145 warm after initial run. It is 150 warm after about a tank of fuel.

Thank you, I try with pictures to give back what I can to the forum since you guys have been VERY helpful in this journey!
Do you think this Tach look VERY similar to the Stihl EDT 9?

I may try ordering that one as I had good luck with Tusk brand for motorcycle stuff.

EDIT: Does anyone know where to get the Stihl combi can in the US specifically CA (we have to deal with CARB )? I am leaning towards eBay?

I'm going to post a picture of the top of both of the farmertec cylinders that I replaced and I'm pretty sure all farmertec cylinders have the same problem it will be a little bit so I'll be back. And what I will be showing you is why everyone gets a false squish measurement but don't scold me for it I'm not the one who makes them. Lol

 

[MG porting]

OK cylinder number one says farmertec on it. and cylinder number two has no name but both have the same issue with the nisi not going all the way across the squish band and in order to get a good squish that nisi on top needs to be mild down my meteor cylinder has nisi all the way across the squish band an it's the opposite it has to much on the inner eg of the squish band but it's doable so be careful take it from someone who fixes and port's saw's for fun you can really muster up if you're not paying attention. All us guys that port saws have been there and done that and sometimes wish that we didn't.

Scold you for what? Only time I ever scold is when somebody does not test their saw which I think is stupid.

It's hard to warn somebody when they just ingore you. They get something in their head and be damned. Almost every time they soon fall off because they have torn their saw up. I don't think that's funny at all.

i just checked paypal. there is no official HL response to my request for the product i paid them for. these people are nuts. why handle a customer in this manner? the paypal interface shows they responded but its blank. likely an underhanded trick like issuing a fake tracking number, lol. $26.43 they must be desperate to aim so high. Notice the not true tracking number. Am I the first guy to order something from them and get a fake tracking number? I had to say something. Businesses are getting away with murder. I just had a thought, maybe they are counterfeiting the sprockets and its being shipped from china and that's why its being handled like this and they have been caught so they are holding their breath. i had a very popular seller here sell me some fake rings, he acted like it got by him, I think he not that big, we need to watch our money.

Looks like a valid #

Why does it look valid? if you look at the fine print they never got a package. they have been notified a label was printed and a tracking number was issued. the devil is in the details.

Those sufaces have been machined. Thats how they are suppose to be.

 

[Bedford T]

There's nothing wrong there. The coating sometimes does not cover completely. You can make that metal shine by buffing it with a 120 pad. Often there will be some "corrosion" not like rust, just a dullness that the you can rub away. Build that saw.

I might mention you should be sure your locator pins are drilled through so it will be easy to knock them out. It makes breaking the case open much simpler should you need to install bearings or something like it after it gets all used and crusty.

Thank you for all the advice

Do you recommend polishing the crank case inner half's

 

[William Prophett]

No

I would where the cylinder sits. It's not required. The best mating surface possible is a reason to do it there. The interior is going to be exposed to fuel and oil and will be just fine
