Husky 346xp compression

[Armosh]

Just finished freshening up my 357xp. Did a base gasket delete, intake boot clamp swapped to metal, piped, carb limiters removed etc. Stock it made about 147 psi of compression. Now about 165 psi, absolute blast to run. So my next saw up for the same treatment is my 2002 346xp. Beautiful condition, bought it from the original owner. So I grab a stock squish reading and then get a quick compression test... 170 psi. Stock. Wow! This thing already rips, now I can't wait to get her finished up. Wasn't expecting the compression to be that strong. My 390xp is mid 155 psi or so for comparison. This will be fun!

Stock NE xpG I had and was told the norm. Guy wanted it for collection so off it went.

Factory 346’s have a bunch of compression. My OE e-tech model was just shy of 170. I’ve since used a thinner base gasket, I should check it again

I'll need to check it again now that I've got it put back together. I was just surprised that a stock saw with a base gasket was putting out that much compression. BTW, I think you're the guy that helped me find an OEM 357xp narrow saddle piston. I finished that saw about a week ago. Was able to just re-ring it and hang onto the new to me piston as a spare. Turned out great, thanks again.
