    timing question

    I was working on my 2.25 SIII timing today. I first static timed it w/ my ohmmeter. set distributor to fire on #1 cyl, set mark on pulley at 6deg BTDC (run mid range fuel about 90 oct), turned ign switch on and rotated distributor until multimeter sounded (can also see points spark w/ lights off).
    I then fired up the truck and checked the timing w/ induction timing light.
    It was at about 2deg BTDC. I reved it up and let it settle down a few times and it does not always level out at the same timing and it takes a while to settle out. It can change by about 6deg.
    Is this normal or is there something else possibly going on, seems to run better except for a very lttle run on when I shut if off.

    Hi,
    It is possible you have worn parts, play in the timing chain, worn cam, and so on. I have always set the timing by ear till I find the smoothest point and best response with throttle. This is because as the engine parts wear the 6 deg. is a reference point to start at.

      I worked on the rover again. This time I static timed the enginge and then timed it by ear until it ran the best. It now idles better, runs smoother.

        Let's go Rovering!!! I just replaced my distributor with an electronic unit, and solved a long time hesitation that I' ve been dealing with. I've just bought a timing light to finish the job. Let me know if you want to get together and get real technical on the timing issue - or we could just drive to Geoffery's Pub.

              Yeah, cheap canned peas are way better. Plenty of gravy too.
