Do we know that we have good, unobstructed, fuel flow to the carb?
yes, i put new lines and filter on, and new fuel pump... pushes fuel out the outlet in a good stream. i have not done a volume test...maybe i should. i will do that, after i put the engine back together. thanks

governor update!!! well, after 2 governor changes (both blew up) i believe i found the problem.if you notice the pic of the governor layin in the block, the shaft came out. i believe it was loose and moving the first time the governor blew up. and, leading to the "hunting rpm's" . after my repair, it is running fine , at low and high speed... rpms are within specs from manual now. i did some mowing with it last night... and it works fine! No surging, no varying rpms,it holds steady wherever throttle lever is.!!! hope i have solved this annoying problem for good! need to get this machine SOLD!!!! the grooves in the shaft, were put there by me, one to help hold the JB WEld to the shaft and block, the other was measured where the set screw is, to give it some holding power on the shaft. yes it was time consuming, but, i didnt have to replace the block... and it seems good now!

My Dixie Chopper has been surging for a while and I thought it was carb problem. Took it to shop for other problem and told repairman it was surging. When picked mower up he said I had a dirty air filter. He changed the filter and problem solved. Cheap repair.....
