@Stovebolt , I am helping out a friend with a Wade blower. If yours pictures is a 34 then would you know if this unit is a 20? We are trying to get as much info as we can for this install on a stock flatty. Hard to find any tech on these old blowers.
@vtwhead somewhere I have some files on rebuilding a RO34 blower 34 = 3400cc air per revolution. I would have thought a RO20 is a bit small for a flathead - unless it is a v860.
