I know, an old 021 POS, but it was my first chainsaw and is sentimental, has always run perfect, but I've been fighting this saw and I think it will still run great, but I can't figure out what it is, so I'll let you guys point me back to the basics.
The story...
Changed the fuel line in it a few years back because it had an old 16-17 year old filter on it and per recommendation, should be changed more often than 17 years. When I go to change it I can't reach it. After joining this forum back then, I decided to get me a new fuel line also. What I found is they changed the fuel line and the in the tank part is much longer than the original allowing for access to replace the filter. I struggled a bit, but figured it out and had a fresh fuel line and filter installed. Life was good.
I recently pulled it out to cut down a small tree and when I layed it on the side to cut, I was covered in gas. The saw ran just fine, but leaked where the fuel line grommet went into the tank. I thought maybe a split or something, so I got me a new line. Pulled the old line out and replaced with the new line. I found no splits in the old line, looked really good. I guess the line had shrunk a bit and didn't seal anymore. The replacement line fixed the leak. Great! Wrong.
I got the saw all put back together, leaned it on it's side checked for leakage, no issues. I go to start it, seems normal, runs a few seconds and dies.
Long story short, I've checked compression, 135, changed spark plug, impulse hose, carb kit, taken the vent off, you name it. I can get it to run a few seconds, maybe 20-30 at times, but it soon dies. It seems like it's not getting gas, which is why I changed the impulse line. Could be a carb problem, but I don't think so. I did put a new kit in, looked really clean, sprayed carb clean through anyway. Put the carb back together ok.
Here's what puzzles me. I lay the saw on the side, fuel fill up, when I set it upright again, more times than not, fuel starts coming out the fuel line where it connects to the carb. Like pressure has built up when I layed it on it's side. I'm thinking vent issue, but vent looks ok, I even pulled the vent hose off and it does the same thing.
I'm stumped. At this point I can't troubleshoot if it's a carb issue, vent, fuel line, impulse line, whatever. Remember it ran just fine before I replaced the fuel line, just leaked out the tank because of the seal. New line fixed that.
So, my next step is to take it back apart and replace the fuel line with the one that leaked to see if it runs again, then it might be a defective fuel line, I've heard of them collapsing and causing similar issues, but I don't think this is my issue, but again, I'm stumped. If it does run fine then I'll assume it was a bad line and I'll have to replace it to get a line that won't leak.
Through all my rambling here, I'm hoping someone says here is what I think you've done and here's your issue. Thanks guys in advance. I'll keep plugging away at it because I'm sure it's still a good saw. I have other nicer saws, 260 pro, 361, 441, etc. so it's not a need issue, but I would sure like to figure this thing out.
