211C starts and dies with throttle
A neighbor asked for me to have a look at their neglected ms211c. Opened it up and immediately smelled bad gas, so dumped it out and put fresh in. Checked the spark plug and air filter, all is good. Starts up great now BUT it will only start if I push the carb shutter all the way closed…and as soon as I give it throttle, it dies. This thing was VERY dirty when I first got it on my bench, could it be that it’s gummed up? Where should I start? I notice that the top trigger, safety, doesn’t spring back up very smoothly. So I am thinking that there may be dirt in ALL the nooks on this.
Also, my saws are older and do not have the “H L LA” adjustments so I am very unfamiliar with how to manipulate those. I haven’t touched them yet, could that be the issue?

It’ll be gummed up in the carb, strip it and clean it, won’t hurt to replace the diaphragms and gaskets while you are in there.
The H L screws adjust fuel metering, a rough standard is 1 turn out on L and 1.5 turns on the H and fine tune from there.
The LA is the idle screw, shouldn’t really need to adjust this.
