800 carb

[cdv]

trying to start my newly rebuilt engine on my 800 gas the carbs usually will suck your hand in when you cover it this pushes air out of the carb don't know whats wrong with it thanks cdv

Cam timing is likely to be 180 out so instead of it being on exhaust it is on intake as in pushes out instead of sucking in

another possibility is stuck intakes..
