so i was looking around on craigslist when i came across a newer revo 3.3 talked to the guy and he said he would take 120 so i want and got it had some problems with the ez start so i went to the pull start

the truck was running but would stall i then replaced the header and put the old exhaust on it and go it running then it died so i cant get it back started and i dont no how tight to put the glow plug and to properly star it

should i re tune it?
