Have a nearly new ms170 and yes I know you pull it until it pops then slide to half choke.

Problem is that at full choke it sometimes wont pop, no matter how many pulls. And you have to assume that continued pulling likely creates flooding.

Yes I have a new plug, good blue spark, clean filter, new gas, a clean carb and plenty of compression..

I mounted up a new carb and see that if used, it also doesn't fully close at full choke.

Anyone studied this enough to find a way to fully close the choke, and see if that helps starting?

If you are the same guy as on the other site, put up some pics of the linkages and carb area.

Crystal Ball is showing a blank right now. Sounds like a linkage issue.

I would demand a refund or new unit exchange. If the linkage is a foul, what else is?????
