My information on the other PSRUs (Ross and Tracy's) is that you must use an
automatic tranny flywheel, probably for the starter position relative to the
flywheel. However, Tracy had indicated to me you just change out the
flywheel, no counterweight problem. Sooo, just guessing here, if the Marcotte
used the std tranny flywheel, just change it out. This make sense?
