If it's a 79 it has auto adjusing camchain tensioner, 78 and earlier are manual. you can tell by looking at your camchain tensioner assm on the back of the block. If it has just a single 10mm head bolt tightened up flush with the body of the tensioner, it's the auto adjusting type. If it has a 10mm head bolt with several threads showing and an additional 10mm head jam nut it's an earlier manual adjust type. If it's manual, you take off your points cover, turn the engine over clockwise with a 17mm socket until you see the cyl 2-3 timing marks then turn the engine clockwise just a little more until the plate has a flat cutout. Right at the point the timing plate turns to this flat area you stop the engine there. Now simply loosen the 10mm jamnut, then the 10mm bolt with threads showing on your tensioner a couple turns, then retignten them. That's it. Whole thing takes about 5 minutes.

at least i think its my cam chain!! it only rattles at low idle and stops at/or around 1700 rpm, then once i hit around 4000, 4500 rpm or so it starts to sound like a plug wire cam off, and it snaps like a electrical spark arching!! ( best way i can describe it sorry!)
when i look down, i see no sings of any spark arching from any plug wires.
also i read a little on adjusting the cam chain, but didnt find any (exact) directions, can some one tell mne haw to do this? what nut tightens , what nut locks the adjustmenst? i have two and dont want to turn them the wrong way and lossen it more!!
