Tmaxx 3.3 won't start
So I bought a tmaxx and have not been able to get it started with an ez start, it will just keep turning over. cleaned the carb, replaced the fuel and checked the exhaust for leaks, nothing has fixed it.
Change the glow plug and reset the needles. Get it fired up and retune. Also sealing the engine will greatly help.

ok already did that, no change..
Air, fuel, compression and glow. Four things for an engine to run.
Air: easy to determine. If the carb is opening, air is getting in.
Fuel: it is pushed by the exhaust pressure so make sure the entire system is air-tight and the carb is not blocking--either by way of debris or the HSN is set too far in. Properly tune it or start back at factory settings (which are rich on the HSN and a little lean on the LSN).
Compression: easy way to tell is spin the flywheel. If it takes a bit of effort to turn it over past TDC then it is good. The real way is to disassemble the engine and push the piston up through the sleeve. If it stops at or above the top of the sleeve it's time for replacement.
Glow: use a glow ignitor to make sure it glows -or- remove the plug, attach the blue wire and hold the base of the plug against a non-anodized part of the engine and push the button on the wand. The EZ-Start system requires the yellow ground wire be firmly attached to the base of the engine and the blue wire needs to be free of any bare spots so that it does not ground itself. Make sure you have 7.2v+ coming out of the starter wiring and 1.5v coming out of the respective glow plug wiring. Sometimes the contacts in the wand get pushed up so that it does not make connection with the harness on the truck. Verify the voltage is at the end of the wires too.
=4 components and you have a running engine. <4 and you have a nice bookend.
ok thanks for the help! found the problem cracked crank case :P have another one that im using. so another thing I want to know alittle bit of the fuel got left in the refueling bottle for a week since I was busy how can I tell if its still good?
if it is air tight your fine
