Ms230

[BrandonJ]

I have no good saw mechanics in the area. I'm going to try to learn a bit myself. My ms230 spits gas while running, my local mechanic can only tell me it's because it's flooded. It has a real hard time starting will never buck on full choke. I do three pulls max on full choke then I go to no choke it takes about 10 pulls to get it to buck and as I said when it's running gas spits everywhere as if it is touching the chain. Any advice as to what this could be?

Welcome. Sounds like a carb issue...metering pin stuck open, adjusted wrong, seat worn out and letting too much fuel through. It's probably a Walbro 286 or Zama C1Q-xxxx. You can pull carb and read model on the sides and name on top. You can rebuild carb with a kit for $6-$10 or get a new carb for $10-15. When so cheap, I pick the latter.

Click your forum name, and it will take you to your profile so you can add your location. Will help to have an idea where you are posting from. The term "buck" is a bit confusing for me to interpret. May be no problem with others.

How does it run after it "bucks" and you make a few cuts? Does it then "warm start" with no choke?

A Walbro WT215 should only be about $30 from a dealer.

Another possible reason for fuel spit back is low compression

[joe_indi]

Other than the carb flooding from a bad inlet needle and poor compression, the usual cause is a sheared key on the flywheel causing the ignition timing to change. This causes spitting and at times a bit of back firing when you have the throttle open

And check the spark arrester screen - can lead to spitting too.
