The chain you used from walmart, is it a 415 chain? Also is the chain adequate length from engine to sprocket?iv put over 500 miles on walmarts Bell single speed chain. no complaints here.
Did you bother to read the thread?Walmart does not sell #415 chain. The chain they sell is the standard bike chain. It`s the same size as the small chain that Gasbike puts on their small engine kits. They are.....seems like #395 size or something like that.
