can someone tell me? or is there something online? I want to completely tear down and clean then rebuild the carb on my sons Eton viper 90r. I have rebuilt carbs in the past for riding tracktors, so it wont be a problem. do they sell rebuild kits for these like a tracktor carb?

pick your model and you have it all. Click on the part # and it tells you the price in a banner at the bottom ...Just bought from them ..pretty happy had parts in 3 days.

As for a step by step for that model ... all carbs are the same principal so if you did them before it's going to be the same , just different shape or size . Take your time and lay it all out ..take pics for reference if you need to.
