altezzaclub Posted July 3, 2011 Report Share Posted July 3, 2011 hmm.. if the cam is in correctly, how about distributor timing. That will cause backfires. However, seeng it was running until you moved the belt, you'll have to go back over it carefully and make sure it is cam timed correctly. Was it firing number one or number 4 when the piston/crank pulley was at TDC? Does it have unequivocal marks on the cam gears so you cannot get it wrong? Do the gears move when you tension the idler pulley? Quote Link to comment Share on other sites More sharing options...
