230psi in a Poulan (42cc, wild thing, etc)!
Link: I found it easier than my Husqvarna 55, since with the Poulan, the bottom of the clamshell is easier to sand since it's flat (sanded on a stationary belt sander) and the bearing pockets are easily sanded with a 1/2" drum sander in a dremel. The work made a much bigger difference in the... -

230psi in a Poulan (42cc, wild thing, etc)!
Just ran it today for the first time. It ran a little stronger than stock. It's still not a super strong saw. It's plenty for the 14" bar, but I was hoping to make it strong enough for an 18". It's the Wood Shark 1975. Same 42cc engine as the Wild Thing. I didn't change the exhaust port other... -

230psi in a Poulan (42cc, wild thing, etc)!
I accidentally free ported my first cylinder with this thing. Bought a new cylinder and this time I went a little too far and reduced squish to almost zero. I can still squish solder, barely (very hard to turn past TDC). I took a little off of the outer edge of the piston top, just incase. But... -

Stock port timing numbers Husky 55 Air Injected?
I ended up using the following numbers from blsnelling on arboristsite for this saw from a 2015 thread I believe. Haven't put it together, but it has to be better than it was with the china cylinder at 70 plus thou squish. I could stop 3/8" 20" chain easy in a cut. Hoping it will pull it a... -

Stock port timing numbers Husky 55 Air Injected?
Squish was probably around 0.070". It has now been reduced to 0.015". Timing numbers will be much different. Haven't checked them yet. No idea what they should be for an ideal Open Port 55 saw. -

Stock port timing numbers Husky 55 Air Injected?
Wow. It's more than 0.062" solder. Just brought it down to 46 thou. Going to shoot for 20. -

Stock port timing numbers Husky 55 Air Injected?
I have 062 solder. I checked a Poulan 42cc and even it was under that. Would the 55 be higher than the poulan? -

Stock port timing numbers Husky 55 Air Injected?
I recently aquired a nice Husqvarna 55. It has 3/8 and a 20 inch bar and I can stall it fairly easy. I'm sure it would do better with a 16 325. But it also has an unknown aftermarket jug. Id like to check the port timing on it. Does anyone have a reference point for a stock cylinder? Muffler and...
