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...
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!..
