I was thinking backwards o no your right thanks. question would the cam and wheel marks not change from stock? Update wow it worked big time . i reset computer by disconnecting the battery and set stock first advance mark on the dizzy. and started it idles so smooth at first i thought it was going to stall, NOT its just smooth idle took a spin around the block and knew it was good,just what i was looking for > just a MM or two on the gas pedal is all thats needed.thanks for your help sir. so whats next maybe an XFI cam if anyone wants to sell one pm me i can offer cash and a very good condition stock cam from a 1997 1.0 and two cam wheels one from a 1995 and one from a 1997 or a complete head with cam and wheel will also consider 3tech xfi or delta xfi cam.

tried that and the belt does not line up.then what turn the lower crank gear? if i turn it then what way? Maybe just best to slot the wheel and turn the cam clockwise ? Edited by socal geo garage, Aug 4 2012, 02:54 PM.

Leave the crank and cam tied together with the belt. The relationship of the crank and cam sprockets does not need to be changed. You are correct in suggesting to rotate the cam only in the clockwise direction. Don't forget that for each degree you rotate the cam it is a two degree change in the timing. The crank rotates two degrees for each degree of cam rotation and the cam timing number is based on crank degrees. |

clark thanks for taking the time here > my motor on my 94 xfi is completly apart and crank has spun a few times am i correct in assuming the cam has to do with compression stroke and not the crank, because ive noticed before the crank mark comes around to line up on compression and exhaust strokes. TDC. thanks again ... what i am asking is when i put the crank gear back to the the mark on the oil pump it does not matter its the head/cam and piston positition that make compression stroke . number one exhaust and intake valves closed? and number one on the cap and rotor?

As long as #1 piston is at tdc ie: crank timing mark lined up then whether the cylinder is on compression or exhaust is then determined by where you set the cam. Line up the marks on the two sprockets and you will be fine. |
