WD45 throttle adj.

Hossman · Jul 2, 2009

Fella"s, On my wd45 when I purchased it the tractor had no gov. response and it would run at what seemed a high rpm. After some research on this sight an lookin over an A.C. book I found that someone had messed with the cross-shaft and had bent it for more rpm"s. Well I re-adjusted the cross-shaft to the recommended specs and the gov. started workin great. Now the problem is that after runnin it in the higher gears I now do not have enough rpm"s at the higher end....My question is do I need to readjust the cross-shaft arm again or as I suspect do I need to look at the linkage?? I know there a couple diff. places to adjust this linkage, is one for idle an one for more throttle?? Thanks for any help. Hoss

Tractor should have a Marvel-Schebler carb- there is an idle adjusting screw on the linkage on the engine side of the carb. That screw is turned to maintain smooth running speed at idle. The idle adjusting needle on top of the carb sets the air-fuel ratio, and the adjusting needle on the lower front of the carb is the load adjusting needle. The bellcrank under the gas tank is where you set throttle to governor linkage.
