I was having a problem with a warrior 350 getting started. I had an old dirty carb that I rebuild for it. When it would start it would rev up to full throttle and I would have to shut it off with the key. I replaced the entire Carb and now she starts right up but still has an uncontrollable rev up at the start. The new carb has a built in mechanical slide and I know it is going up and down. I was thinking air leak? but would it cause it to rev that high?

Thanks in advance.
