Sthil 034 warm weather problem

[grillzy]

I have an 034 that is about years old. The saw has been great when the weather is cold. When its cold out -5 C or cooler the saw runs great. If its warmer out the saw runs like crap. Been like this since new. The saw stalls if your finger lets off the trigger. It will not rev out. Anyone know what to do?

Running rich?

ether always has results but for a limited time period...

So if its running rich then what do I need to do?

Never use ether or starting fluid on a 2 stroke... Is your air filter clean? Fuel filter old?

Also... post this in the chainsaw forum a little further down the main page. you'll get more answers.

yeah i was just kidding about the ether,if iwere you i would borow a compression tester warm the saw up well and test the compression anything below about 85 90p.s.i.will not run once it warms up,if your compression is good you are probably sucking air through the crankshaft seal,an easy way to test this is remove your clutch to access the crankshaft and with the saw running squirt some saw gas around the crankshaft seal area if your idle suddenly climbs you know it is sucking air wich if thats the case we part the saw out for we found its not worth splitting the cases...oh probably not the issue you are having with the saw but a cheap easy 'try to fix'that might be worth a shot is to replace the diaphram in the top of the carburator but that does not sound like what you got going on
