I installed the 7-speed chain to the 24t chainring sprocket.....
and it rubs on the edge of the 83-tooth timing pulley.
Normal chainring sprockets are less than 1/8" wide.
The 83t pulley is an inch wide.
I'm using the 83t cog as a chainring sprocket, which belts onto a 17t jackshaft sprocket.
Solutions could be to move the 24t further inward.....
or space the 83t pulley further outward.....
or both.
I may have to reverse the sprockets and have the 83t pulley on the inside,
and the 24t outside of the bottom bracket.
Last resort is to replace the 83t/17t pulleys with 36t/10t chain sprockets and a 16t clutch.
