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. |

Alright...got the P&C's off again. (IMG:style_emoticons/default/headbang.gif)
Good news is that I put the flywheel on and some paper towels under the ends of the rods and the crank ass'y spins nice and smooth. I took out the 3 spacers under the flywheel and I've got .040" or so play. I'll re measure with the 2 spacers to see what I got. Going to Rimco tomorrow to recheck and have them check the boring of the cylinders and the skirt clearance on the KB 96mm's. I'm not sure what it should be or where to check it but I"m sure they can figure it out. What should the gap be on the piston rings? |
