Chainsaw Repair

Wonder where the butterfly and screw went to.

Don't know but she took it to a shop and they told her $130.
She didn't want to pay that much as, that's what the saw cost her.
Maybe they took it off out of spite.
The 2-hole link where the blue plastic choke lever attaches was loose and turned backwards so I'm assuming they messed with it to some degree. Don't think she would have attempted to do anything with it herself. Who knows. Hubby maybe?

There's probably not much vacuum (or positive pressure) at the air valve is there? I thought about plugging the air valve throat with a vinyl pipe cap temporarily just to see if I can get it to run. Don't know the condition of the carb diaphragms.

If I can determine that the carb will work, she would probably not mind payin $30 for a new air valve. Bar some other problem showing up, such as the oil pump.
