Hi guys luv my 310-8 did a total rebuild on the Magnum 10 Kohler last summer since she was blowing chunks of carbon, ring end gap was 40 plus, now with new rings, piston and hone job she is just about perfect. I want to now attack the drive speed she is too slow mowing in 2nd and too high in third. It has a 6 inch 5/ 8ths bore Drive pulley if I change to a 5 inch diameter pulley would this solve the problem (mowing in 2nd)? assume going to 4 inch would be to much? I also have a 4.5 inch.... any recommendations here would be appreciated. DO NOT want to do anything to hurt the transmission. Thanks
