O.k guys, I have a brain wrecker for the saw gurus out there. I bought an older 394xp off an old school logger, brought the saw home and hung a 28" bar on it. The saw was very lazy and since it was my first Husky, initially I used it as an excuse to stay brand loyal to Stihl. And even though I got the saw pretty cheap, I've been knowing this guy for years and sticking it to somebody is just not his nature. But like I said, it was my first Husky and I was reluctant to twist on it because I've never ran one. I did a compression check and saw blew a little over 150psi. Even pulled that funky clutch set up off and made sure the saw didn't have an 8-pin on it because he loves 8-pin sprockets. I ordered a dual port muffler put it on and looking through the exhaust, piston looked great!
Well, when I went to adjust the carb to compensate for the dual port, I found an obvious problem. The hi-speed jet was turned all the way in.........and I mean ALL THE WAY In. I adjusted the carb, same way I do a Stihl and immediately, I could tell a huge difference. Now I didn't run the saw much prior to finding this because I was always disappointed in the performance and determined to find out what was wrong! Now in hind-sight, a carb adjustment should have been the FIRST thing I checked and I know this......... so please don't beat me up about that.
What I need to know from someone who has the knowledge is how in the heck did this saw run at all with that jet closed all the way off. And what do you guys think are the chances that this saw has no lean condition damage. 150-155 p.s.i. on compression reading is that good or bad for this saw. Please chime in.
