    1972 cl 350

    Have a 72 cl 350 with 82000 miles, timing chain broke so I put a another motor in it that had lower miles, 140 lbs compression both sides. Engine turns over but will not try to start. Spark is good on both plugs, I turned engine over by hand and everything is happening in proper order. Valves have proper clearance, I am going to take the carbs off and spray starter fluid in the manifolds to see if it will run at all. I would appreciate any suggestions.

    Make sure your rotor is not 180 degrees out. No reason to take the carbs off, to try the starter fluid.

    1972 cl 350 rotor is correct, left points fire when left cylinder is on power stroke, engine just poops out exhaust and carb, it acts like timing is off but it seems to be dead on. any suggestions welcome

    Your spark advance is off or you're plug wires are swapped.

    In what position is the spark advance unit supposed to be? It appears there are 3 ways it can go.

    There really is only one position - there should be a pin in the camshaft, 90° to the shaft where the advancer goes on, and a notch in the back of the advancer to fit over the pin to properly align it. The other potential problem is the breaker cam itself on the advancer, the lobe that opens the points - it can slip off the advancer during removal and can be put back on 180° out. the pin is #12

    Try swapping the coil wires. Your left points going to the rt coil?

    the left point wire is going to the left coil wire. Everything looks right doesnt make sense that it just poops and pops.

    I'm pretty sure your timing is 180 degrees out.
