So who knows the 22 cubic inch engine well? It has a long great history. I recently picked up a 20BA75B which seems to be quite a rare bird. It's a Johnson 20hp from 1975 made in Canada. It appears to be the same as the 25hp engine from that same year other than the fact that the 25 revs at 1,000 rpm faster. The 20hp came missing most of the ignition parts up top including the flywheel and looking in pretty rough shape. It also has external coils. So my question is two fold, a) can an older 22 cube engine from the late 50's with magneto's bolt up if I wanted to change the power head outright, or can I move the entire ignition plate and flywheel over off a similar vintage engine and get it up and running? Any ideas or comments would be appreciated. Thanks, Steve.
