RE: gear mesh question?
Hellya: I forgot about the Fg Pinion gear being 16 tooth,,,,To be used on the layshaft....
I know pinion and the spur gears are different... Between FG & Firehammer,,,Should stay with the firehammer gears....
I think if I remember Innovative Hobbys has a metal gear set for the firehammer..Both Pinion & Spur..
Or you can get just the 19 tooth steel pinion gear and leave the plastic spur gear...........
