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?
