Does it matter what the clearance is on reed cranks against the housing outside edge of crank ? ie thin edges.
If i had the housing enlarged to 100mm diameter and then used a standard reed crank would it work ?

anyone ?

"the housing outside edge of crank" More info would be helpful here.

What's a "standard reed crank"? Is that like a stock hot rod?

If I had to render a guess, is this for a vespa?

Not trying to be difficult here but the details are important if you want actual relevant help.
