Since I don't want to hi-jack some other post, I figured I'd start my own for this.
As stated is some other threads, I am doing a little work to a buddy's 029. He never did any maintenance to it, just spark plugs, bar, chain, etc.
We were out cutting one day when it began to bog down in the cut. Reving it with no load, it was fine. We cleaned the air filter, changed the spark plug, and changed the fuel filter (which was never changed in 13 years). It ran okay, but still not great. Brought it home with me. Tore into it and found some very small cracks in the fuel line, impulse hose. Carb was full of crud. Replaced the hoses, got a rebuild kit for the carb, and cleaned the saw up. Did a muffler mod as well. Didn't go outrageous, just an two more 5/16" holes. Put everything back together, set the carb screws back to factory (1 turn out) and proceeded to fire it up. I am having trouble getting it started. I choke it, it turns over. Flip the choke off, and it wll run for 2 seconds on the throttle lock setting and die. Get it to idle for a few seconds but can't get it to throttle up. It bogs down. Try a few different L settings to help with starting, but can't find something that works. Still hard to start, will fire with choke on, bogs when throttling up. I "sometimes' can feather the throttle to keep it running, but not for long. I have taken the carb back off and re-cleaned the entire thing, thinking maybe I missed some dirt. Particles were so small and few, that I couldn't tell if they came from the carb or the workbench.
Same deal even after the carb cleaning. I am at a loss. The saw at least ran when I brought it home, now I can't keep it running... Help.
