I'm ready to assemble the cyl-piston assys into the crankcase. Is there a preferred order ? Like 1,2,3,4,5,6 or 2,4,6,1,2,3. Etc. This just has to do with ease of getting to the bolts to torque them. I have built several engines in the past 40 years and can't remember if one sequence had better access than an other. Thanks.
