since the subject of swapping sides on the exhaust came up. I have the older irvine 40s, a Q40 (the Q40 SAME AS THE DIESEL)
except for the head, and the crankcase appears symmetrical would it work on these? just a rhetorical question since I do no have the need to do so
I think I just answered my own question the intake passage slot is lower in the crankcase than the exhaust just noticed this,not aware till I saw Bills answer
