I installed a new carb.gas filter is clean tank vent is open,fuel line seems to be in good shape,good spark. It seems that the fuel pump in carb is not getting the vacuum impulse to pump. Any ideas??

Thanks again for you time and help, Butch [Reply]  [No Email]

If the crankshaft seals start to leak they will cause the problems you are talking about. They let air into the lub system. [Reply]  [No Email]

Now the 2nd saw had been running fine , but then it started doing just exactly what you say your 353 is doing . My friend finally diagnosed it at being a bad coil . Coils are big dollars . I do hope this helps . God bless, Ken [Reply]  [No Email]

Some of the real oldies used a rubber(y) seal about 1/2" long that went in a hole just below the carb. adapter and a nipple on the plastic adapter just mashed down into it a ways. Either type can give trouble such as get old and crack, etc. [Reply]  [No Email]

They will act the same way if they are sucking air from a leak in crankcase. [Reply]  [No Email]
