 Topic: 712h only runs with full choke when PTO is on
Posted: 18 Jun 2016 at 3:24pm |

So our 712h when mowing (PTO engaged) will only run when the choke is left wide open. Other than that it's fine. Any ideas?

Yeah, I'm wit' Hud on dat one. You have dirt or varnish pluggin' up the enrichment nozzle making the engine run real lean. Pullin' the choke closed most of the way fattens the mix, and cut off the air charge. Time to "rooto rooter" the Carbatrator....

You might try running some Sea Foam through it. There are full load mixture adjustments on my gas garden tractors, also. Run it all the way in to get rid of anything that might be in the orifice and then back out to where it was. If still won't run well, back it out some more.
