T250/GT250 Ignition Timing

Post by Tripleking »

OK, just got the engine back from the machine shop. I don't have a good TDC gauge so I want to set the basic timing using a test light, but I cannot remember how. I think I need to adjust the points so the light goes out just as the timing marks line up. Am I correct?

that's right, set the points gap first to 0.35mm / 14 thousandths, then adjust the timing by rotating the points backplate until the timing light goes off when the timing marks line up.

You may need to recheck the timing when the engine is running, with a strobe light.
