1976 Honda MR250 elsinore project, with .004 vertical clearance at the flywheel. Disaster?
my 76 mr250 project is very nice in all respects and has 3930 miles with 150psi compression and nice spark. off the road since 2012, previous owner said it was hard starting and sold it to me. found the timing nearly at "T" due to worn points follower. set the new points at "F" and started with much white smoke. carb inlet/outlet, top of piston and plug wet with gas. noted maybe 1/2inch fuel in the crankcase. thought i'd deal with that and carb tuning in the spring so i'm in the middle of a complete mechanical refresh at the moment.
just noted vertical clearance of 0.004 at the flywheel, with zero side-to-side and zero endplay. my service manual gives no spec, but this seems excessive. am ok with top-end work, but have no tools for splitting the cases. am wondering if i should continue on my current path, or part it out because the engine is toast. many thx,
