MM, Good writeup, thanks,I enjoyed reading this, but could you please elaborate a bit more on point 8 that said "install the oil seal" ?

I have found that the space between the mag pinion and the crankcase housing is too narrow to fit an oilseal, and I fabricated an alternative solution that is not 100% oil tight.
Not sure if I use the correct seal, Do you have a part nr. or seal dimentions ?
