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. |

It was a good trip.... Relaxing and now I'm ready to kick some serious ass and get moved into the new shop!
You will encounter some resistance, but it will not be drastic. It is imperative when assembling an engine that between assemblies being installed to rotate the engine and get a good "feel" for what the assembly did to the way the engine turns. Doing things this way ensures that drastic differences are caught and the finger can be pointed to the problematic area easily. Yet again I ask about piston/skirt clearance and what pistons and cylinders you used.... If you have to be scared- do it, you only have one chance! |
