Stihl 341 & WD40

[colwoodlandcare]

Used the saw on sunday, stopped it for some sharpening tryed to restart it and nothing, wouldnt start monday either. Tuesday sprayed some wd40 into the carb and after a few pulls, fired up abit smoky, worked fine for the rest of the day.

What could have been the sympton and why would wd40 sort it out?

Displaced water maybe? Either way I'm keeping some Wd-40 in the cab from now on!

Maybe it would have started on tuesday anyway? Who knows. Why did you decide to use WD40 on it?

 

WD40 is like the footballers magic sponge!! Seems to cure everything that wasn't broke in the first place.

Who knows, maybe it didnt like the idea of working all day sunday and decided that monday would be to teach me a lesson. Not sure what processed me to use Wd40

[skyhuck]

I seem to recall that the "WD" stands for "water displacer", so maybe you carb had Some water in it that was displaced, those curing the problem.

I'd say you just flooded it on Sunday and it was ok by Tuesday and the WD40 did nothing, well except make it smoke.

 

Usually its a bit of easy start thats gets sprayed into non starting engines, never tried it with a chainsaw though!

Say the saw is low on compression, spray the WD40 down the carb, it enters the combustion chamber, seals the piston, raises the compression and bang - it starts!

Or the Wd40 vapour combusted more readily than the petrol vapour, getting it started!

Lynx is also good for starting engines on cold mornings!!!! lol
