generic possum grease, actually I used a high temperature silicone gasket compound that I had in the rollaway.

Is that made by the same company that makes the liquid penetrant weasel piss?

Hope that sealant is gas/oil proof or your going to be replacing that top end again! Can you say "air leak"... from the gasket material being ate away.

It's labelled uv, oil and grease resistant. Brand is GE Gasket and Sealant. I report back if it starts to idle funny.

Oops... there it is.... at that point, it may be to late! Someone else may chime in on the correct type to use, tons of threads on this issue. I use Dirco(sp?) from the Stihl dealer, permatex gray, Yamabond and a bunch of other brands that is made for this type of gasket. I'm not familiar with the brand you used but the issue is that fuel will eat most sealers.

Someone else may know different?

gas eats silicone for lunch......oil and grease are not solvents, gas is. make a little squirt of the stuff and let it "dry" get a tiny container like a baby food jar and put some gas in it. throw the cured/dry squirt of stuff in the jar, let it sit for day or so and pull it out and see if it is still "cured" most likely it will fall apart in your fingers into crumbles. I asked the techs at our local pro saw shop what they use, the showed me a tube of silicone sealer.....they were not aware of the service bulletin that told them not to use it. It will probably work for a while but not forever. There is only a very small edge exposed to gasoline, but eventually it will most likely break down.


I use permatex moto seal, it is designed for that application.

I learned all this on this forum, Modified Mark was the first guy to point it out to me. I have used silicone in the past for patching weather checked, cracked rubber intake manifolds on motorcycles with some success but in that application it is a temp. fix and the operating conditions are vacuum and atmospheric pressure only.

Thanks for the info. I will find one of the recommended products, take both saws down again, replace the compound. things are slow at present anyway and puttering with saws keeps me almost together. it would be better if there was a kegulator in the shop.

I use 3-Bond , get it from Northwoods saw place. Site sponsor here. Think its the same as yamabond,hondabond, and others. A tube last a very long time !

Tbone...he pulled out a few months ago.

Well **** !

I don't get out much !

Haven't bought from them in a while either.

I thought it was interesting that the guys in the pro saw shop are using a silicone sealer, the next lean seizure is probably a couple years down the road and it will be blamed on something else...seals most likely...opcorn:

A real shame they didn't know that..:msp_sneaky: What happens when they don't receive proper training. I'd be looking for a new shop!

 

[heyduke]

O'riely's is the only auto parts store around here that stocks the permatex moto seal, around $7 a tube, half a lifetime supply.

That's where I went. That's what I got. Have a 380 magnum on the bench waiting for rings, due tomorrow. The Makitas are next in line. "Chemicals, I need chemicals!" Hayduke, from the Monkey Wrench Gang, Edward Abbey

I just installed a 48 mm p&c kit from hitzl on my 034av making it an 034 super and i run my saw pretty hard so I will update you guys with my experience also what is squish and how does it effect the way a saw runs

Squish is the distance between the top of the piston and the "squish band" which is an area around the top of the cylinder. Too much or too little "squish" will affect the engine compression. If you don't have enough space, it can actually damage the engine. Too much space there and your compression may be lower than desired with resulting poor performance. It is commonly measured by placing a piece of soft solder on both sides of the piston top, running the cylinder through a TDC cycle and then measuring how much the solder was "squished". ie, how thick is the solder after being flattened?
I only check this if fitting a new to me cylinder on a saw.

 

[fearofpavement]

I should add that the solder is held in place by a dab of heavy grease. You don't want it getting into the crankcase or other places.
