Traxxas T-maxx 3.3 constantly revs up

[bjohnson80]

Ok so I have an old school T-maxx that I installed a 3.3 in ran an drove fine for a couple of tanks using 20% fuel. Then backflipped over a curb ended up on the top now revs to no end, all the carb adjustments barely do anything.
Need help thanks...

It sounds like you've got an air leak from the acrobatics. Here's an older article that has some info: https://www.rctalk.com/forum/threads/symptoms-of-an-air-leak.72359/

@hamz9561 beat me to it. Check your fuel lines. I little pin hole can mess things up.

If you installed a new engine to an old platform ,you also might want to make sure
that the fuel tank is cleaned ,any old residue can restrict fuel flow that will
cause lean condition an cause the engine to rev as well!..

No tank was cracked and leaking so I replaced
