Back again with a resurrection of an older post. Same mower that I worked on before.....Here's a little summary......Mower would run for a while then start surging and backfiring under a load. Cleaned and rebuilt the carb and had a problem with the motor not returning to idle. After fixing a probable air leak it seemed to run fine for a couple of months.

Now it is surging and popping only under no load. Once the PTO is engaged it supposedly runs alright. ( I personally have not gotten this machine back yet).

With my limited knowledge I am suspecting a carb issue. Any suggestions about anything else to look for would be appreciated.

model 446677
type 0463-E1

Thanks Jack
