Chainsaw Stihl 029 is running poor as it takes about six pulls to get it started then runs weak for a few minutes and even after warming up it seems to run out of gas and stall in the middle of a cut.
I ordered and received a ($17) kit from Amazon which included the gas tube to the carburetor, also the vacuum tube, several tank fuel filters, a new sparkplug and even a new carburetor.
I installed all above and engine would not run. When pouring about a quarter teaspoon of gas directly in the carburetor the engine would run for about six seconds.
I compared the diaphragm in the carburetor between the replacement and original carburetor. The original carb's diaphragm appeared more flexible and of higher quality but had some contaminate clogging its operation. I carefully cleaned the contaminate and installed the original carburetor and the saw worked as designed. So the main problem was likely contaminate on the diaphragm of the carburetor.
Now I look forward to sharpening the chain and adjusting the low speed of the saw as it now runs too fast at idle. I did make 3 large cuts and the saw had plenty of power but cut slow due to a dull chain. The saw was starting with two pulls rather than the six and ran well even before being warmed up.
