RE: Official HPI MT2 Thread
Straight after the engine stalls check the fuel line, see if you can spot small air bubbles in the fuel line, if there is that means it is the primer on your tank leaking. Allow air in to the fuel line will cause the engine to lean out which, in theory will cause it to over-heat and stall. I would not dismantle the engine unless you are 100% sure you know what your doing. I would start with the basics first like fitting a primerless 100cc tank first, this could sort your problems out. If this fails then i would seal the engine head gasket with gasket sealent. If your looking to upgrade parts on your car firstly i would suggest you get a FAILSAFE i would also get the gpm/edit steering knuckles as the plastic ones are very weak and cause you to loose screws. Another good investment would be a fuel filter & a high performance air filter.
EDIT:- Also check your MANIFOLD screws, The smallest ammount of play can cause problems.
