Ok, I've finally cut the p-rods and am loading them in and adjusting the valves. Right now it's on TDC for #1. I notice that when I turn the flywheel, at some point in the rotation there is a little tightness for a few degrees, maybe a 1/4 turn or so. My jugs were opened to 96mm with new KB's and hastings rings. Could this be just the rings on one of the pistons when down low in the cylinder? I don't know how free a new motor is to turn. The crank turned smooth as silk before connecting the rods, p&c's etc.
My hands hurt from the teeth on the flywheel so any thoughts would be great. |

If the engine doesn't spin freely- It will die a painful, short lived death!
When did you note the engine starting to get difficult to turn?? What is the end play set to?? Let me help you through this because otherwise you can become a statistic very quickly.. did you set the skirt clearance on those cylinders and pistons? Where did they come from? All are NOT created equal and some are screwed up right out of the box! |
