My 340 build

you're probably ok , new engine's before break'n are a tad tight. mostly from the new rings and cylinder finish.
Really? That stiff is normal? As soon as i remove rods and pistons the crankshaft spins nice. My rod bearings measured .001 chamfer correctly orientated to crank,ring end gap spot on everything is squeaky clean...i did have a lot of assemly lube on bearings and 30 weight oil on cylinders and pistons to ease install. Has anyone ever had such a stiff rotation? Looked up countless times, cant find nothing read every book and shop manual i have but still nothing that helps with info, could possibly a rod on the wrist pin being getting hung up, im just tring to brainstorm:BangHead:
