ms271 Sticks at full throttle during startup procedure
I replaced the carb on my MS 271 after 8 years of moderate use, maybe felled 200-ish eastern hardwoods and cut into firewood. During startup procedure, pulling the trigger to idle down from full throttle doesn't work and I then have to force the choke lever to 'off', which pops my throttle linkage out of its little plastic slot. I try it with the cover off not running and can see the choke lever/spring not moving off the white plastic hook. Any recommendations for fixing this? My throttle linkage pops out of plastic grove sometimes too if not very gentle with it during startup. I considered taking the fuel pump and metering diaphragms out of new carb and putting into old carb as I think that was its only issue. Saw has never seen ethanol. Spring on the new carb feel strong but blip the trigger doesn't trip it to idle during statup. Any help appreciated.
