    MS461 carb adjustment: RPM too high on full throtle

    I’m trying to adjust the carburetor on my MS461 and I have 2 problems: 1- I cannot lower the RPM on full throttle below 13800. 2- when the saw is idling (2800-2900rpm), the chain run a little bit (it moves a inch every 1-2 seconds). Is that normal? Thanks

    Stihl MS211 Bog

    Hi, as you may have seen on other threads I've posted today, I've bought a MS211 as a non starter for next to nothing. Managed to win the first battle and got life into it after some tinkering. Next issue is the ungodly bogging I'm getting. Anything over 10% throttle and it sounds horrible...

    MS211 Fuel Issue

    Hi, I've got a stihl MS21, hasn't started from the day I've owned it. Tried pulling it and an ungodly amount of fuel has pi***d everywhere, the exhaust is full, it's coming out of the carb and dripping down the handle. Something catastrophic is wrong, but what?

    Poulan 2000 won't start

    I was recently given a poulan 2000. It will not start. It seems to have good enough compression, it has spark. I'm thinking maybe the carb? I just don't have much experience with them so any help on how to troubleshoot would be great.
