Re: Vortec Test
when you pull the dist out to indicate worn or not worn, flip it 180 and put the wires on so that thier right. see if you can make the problem jump to a different cylinder. make sure you keep everything in good time. if the bushings are in fact worn that would cause a flutter at full throttle to. due to the pickup missfireing. what do the plugs look like. is one different? the same. if the problem jumps from cylinder to cylinder, its fuel most likley. if the problem jumps to another cylinder when turning the dist 180 but stays in a specific cylinder, its the ignition pick up and bushings, or plugs or wires. if the problem satys the same... its something with that cylinder, valve flutter, bad lap job. its time to narrow out each possibility with several tests each. one specific test ist a 100% guarentee that thats not the problem. start with one subsystem and start from the top. do the easiest first. rule out all possibilities. im with don. quit jumping around and do complete tests, on ALL subsystems. make a list, and check things off. be sure to do at least 2 different tests for each thing. then check them off as you go. do a complete subsystem check then move on to the next one.....obviously theres something wrong. your just bouncing from thing to thing to much. each i mean subsystem as electrical, ignition, fuel,cylinders and heads. id buy a complete drop in motor if i was in your shoes instead of a long block. oh rapido marine is 150 to ship. unless your here in southwest florida, then its 75. i just pick them up from there.<br /><br /><br />hey! move down here its usually always sunny. except now when the hurricanes move through!! haha i think we have had 6 inches of rain this year.... that sucks really. fish moved out and my canal has dropped two feet?!?
