[QUOTE="Tazza, post: 76447, member: 82"] On a Kubota, for it to slip a tooth on the timing, something major is wrong, it's all done with gears. The injector pump is timed with a cam shaft that goes to these gears. Do you get any smoke as it's cranking? I found that spraying in WD40 and winding it over should get it to jump too. I was cleaning an engine one day on a bench, it had carbon on the inlet manifold. I took the manifold off and sprayed WD40 in the inlet ports and brushed with a tooth brush, i wound it over to blow the crud out. guess what tried to jump off the bench?......... No fuel was hooked up, it had not been started in years, the WD sure woke it up from it's slumber. Checking the compression isn't a bad idea, but as it started and ran, i really can't see why it would suddenly drop compression on all 4 pots. [/QUOTE]
