Hi,
I'm a homeowner, not a professional, and cut down & cut up approx. 4-5 trees per year (14"-28" mixed oaks).
Some years I don't cut any.
Anyhow, I have a Stihl 025 which starts easy, runs well, and is no problem starting back up when hot -- UNLESS I let it sit for about 10-15 minutes after having run it for awhile. Then it won't start or even fire no matter what setting I try (hot/cold switch) or how many times I crank it.
However, if I remove the spark plug and crank it a few times and then replace the spark plug, it will start with the first pull (on the hot setting) and then run well after that. I thought maybe I had flooded it while trying earlier to get it to restart, but the spark plug is dry.
The saw is 25 years old. The Stihl dealer says that at that age it could be any number of things, e.g., a fuel diaphragm, or other parts of the carburetor, or the fuel line, etc.. Cranking it without the spark plug causes it to crank a lot faster, which probably corrects the problem, which then allows it to restart. He says that I could spend $50-$100 dollars to repair it, but if it was him, he would replace it with a comparable saw, like the MS 250. He says that if I've gotten 25 years out of it, then I've gotten my money's worth, and I see his point.
I'm was just wondering, however, if someone on this site might know something more specific in regards to the symptoms of this problem.
Thanks,
Mark
