In a traditional upright inline engine (i.e. 4 or 6 cylinder found in any watercooled car) can overfilling the oil reduce or limit engine RPM by touching the bottom of the bores of the cylinders?
I have a 1 liter 3 cylinder Kubota diesel. Book says 4 quarts and that's what I put in. After running for 15 minutes to warm up, it won't rev beyone 1/3 RPM potential. Dipstick shows almost 1" over "high" presumeably after the oil filter has done its thing and purged air. I'm just guessing, but the oil level may be as high as the bottom of the bores. Yes, I can drain oil to the mark and restart, but I want an arsenal of other possibilities so I bring the right tools out with me. |

It's still an air pump. Check intake and exhaust. Shop rag in intake?
