    Rpm started going up and down. Seem to only do when blade are not engaged. Smooths out while cutting. I dont know the actual rpm's but as an example its like 500rpm for a few seconds then 1000rpm then 500 then 1000 back and fourth. Hope its an easy fix.

    One thing to check is, make sure the welch plugs are in the top of the carb body. If one is missing, it'll give a surge. Under load, it's pulling more off the main.

    You can seal 'em up with a bit of epoxy. (Sparingly )
