I just finished my Farmertec MS660. Runs fine but during the first long cut it seemed to not have much power. Is that mainly a carburetor adjustment?
Thanks I do have it a little bit rich and will readjust.Could be carb adjustment or timing. I’ve found that the Farmertec flywheels have a lot of play in the key way. It’s important to hold the flywheel counterclockwise against the key when torquing the flywheel. The power difference is noticeable. I also run my new builds a little rich for the first few tanks to facilitate good break in. They wake up a bit when you lean them back out. Also check your squish or test the compression to make sure it’s good.
