MTD yardman push mower surging

AroniaFarmer · May 22, 2012

I have just recently got a free yardman push mower. It looks like it has a Honda clone engine on it. When I got it home one governor linkage was off, but nothing else looked bad on it. I put new gas in it and started it. It was surging and running rough unless the choke was on or it was under a heavy load cutting some tall grass. Is this a governor issue or a carb issue?

Carb needs cleaned. But check the price of new carb, because kit plus time may cost more than the carb itself.

I cleaned the carb with carb cleaner and blew it out with compressed air over 2 times now and it still runs like crap. I think I am going to buy a new carb for it

Make sure you have good gas flow into the carb. Things like junk clogging or partially clogging the fuel line, or stick float needle valve can cause your symptoms.
