i have no prob starting the truck afterwards, thing fires up right away. the only time i have problem starting it is when its cold, but that may be due to the glow plug needing replacing, Ive heard about the air leak problem, just wondering how does that affect the performance of the engine?? but ya ill pull the motor out and have a look, i sent the truck rolling few weeks back and broke the motor mount so maybe i cracked the carb housing
