Dolmar Chainsaw Guide

Hello guys,

I’ve noticed that it takes a lot more pulls of the starter rope to get my Dolmar PS-421 to start now, and even after starting the engine starts to sputter and choke. Why is this happening?

Hello Finch,

I think that your carburetor needs to be tuned according to the weather or the change in weather there – it sounds to me like the air fuel mixture you are using is too low and needs to be cranked up ever so slightly so that you are providing the engine with enough fuel for operation, especially in colder conditions.
