So far, everyone I've described this problem to has just stared at me in disbelief. My saw will start on the first pull but, as soon as I lift it off the ground or stump or whatever the surface, it shuts down immediately. Currently it is disassembled only as far as I can remove the kill switch. I "think" I would like to get to all the electrical parts to check them out but, I thought I would ask the forum before I went through all the agony of further disassembly. Any one else had that problem or, any thoughts about what may be wrong?

If I leave it on the stump, pressing down to keep it secure as if I were pulling the cord, it runs normally, accelerates, slows, etc. To the second questions, I cannot shake the saw since I cannot lift it without it stopping.

 Here's my guess.......... There's a split in the carb boot. Holding the saw down keeps the split pressed together, but when you lift the saw and it flexes on its antivibes, the split opens and starts sucking air. It may well be a grounding issue too, but I'm going with split boot. Dan

OK, I'll disassemble further looking for a split boot and any electrical problem. I think I saw photos from this forum that show how to get to the boot. Seems like a bear to do. Thanks for the tips.

Okay, I'm in the process of trying to get this thing apart and the engine housing feels really loose. I can move it all around but cannot figure out how to get the fuel tank off. That seems to be what is keeping me from separating the parts. The tank's fill spout seems to be stuck in the casting that I can't push it through? Any tips? (here's a second issue to address later: while "wiggle/shimmy/twisting" this thing, a metal ring fell out. From where I have no idea. It's exactly 0.5" od, about 0.08" high with about 0.25" "wall" thickness. I'll scan all the exploded views I have but, if anyone can tell me where it goes, I'll buy you a six-pack.)

Sounds like one of the rings for the VI mounts.
Do you have an IPL for the 330?

My youngest son just (and I mean like last week) moved from GA to MN. Don't yet have his address but, I'll see if he's near Detroit Lakes.

I gotta walk away from this for a while. I cannot get the casting to part from the gas tank so that I can remove it (the engine housing) and, although I know you all have done it, it looks near impossible. I'll try fresh in the AM or, after I stop shaking.

Don't feel alone.... getting that dern plastic tank free of the housing is one of the most frustrating parts of working on a 330, at least in my opinion. The tank will pull up from the bottom (just a little) and the neck will tilt down and reach an angle that it'll come out of the hole in the body housing. It can take some force to get it out, at least for me. I never can easily get the twist just right for it to come easily. Don't be timid about putting some muscle on it, and of course remove the fuel cap first so it will clear.

When I went into the shop this AM, I sprayed some lube, CRC 2-26 which is safe for plastics, all around the tank and left it for about an hour in which I built up my courage. I really don't know if that was a factor or not but, the removal of the tank was like one of those metal link puzzles in that when I got everything aligned right it fell apart into my hands. Now, after I get everything cleaned and obtain all that I want to replace, we'll see how it goes back together. I did take some digital pics to help me with the hoses.

Oh, forgot to mention that the boot was split. So, thanks to those guys who suggested that was the cause of my "mysterious shutdown".

Good news/bad news. Good news is your half way home. Bad news is that its harder to get the tank back in than it was to get it out.  Just kidding.  You do know how to properly apply alcohol to make things go smoother, correct? . |

Yee haa! I just cut a bunch of firewood and my saw worked great. Had it not been for this forum I would have had no clue how to fix it. Thanks.
