It could be a sheared flywheel key. anyways, verify timing at TDC and if it's off as you mentioned pull flywheel and inspect.

No way it's gonna run at 180 out??
Basics, compression,spark.
Manual? Find TDC and see where the marks align.pics?
The 50 will run and run fair on 1 cylinder.

Ok for all the looks i got when reading this post im sure i would have deen one and the (basics) comment heres what i found new cd box was bad when running with plug wires switched it was only on 1the cylinder with it back to correct it was on both (found this out at local marina he had seen this once before with a brand new force back in the day and said change it) it worked now as for timming it wasnt 180 out he couldnt figure out why mark was on wrong side except part #for was wrong so he just re marked and adjusted timing witch was pretty good now all is well and also standeredmagnito was great they had my replacement here in 24the hrs after marina contacted the for me at just shipping charge i thought for electrical part that was great

Sentences would be nice to help us follow what you are trying to say.
