911 issues Options

[ripper911]

OK, my 911 is cranking about once a day.

Yesterday it cranked with my brother messing with the wire that runs from the coil to the distributor. Today I made sure it had a good connection before trying it, and it cranked and idled well. I moved everything out of the way to test drive it and it wouldn't crank. It may have flooded, there was a strong gas smell. After trying to crank bit for a minute it started sounding bad, it was popping or knocking maybe backfiring while trying to crank, but after that it would only squeal when engaging the starter so I stopped.

There's something going on...

Your "new" starter could have a bad bearing.

If the float level in your carbs is to high ... you can flood the engine and it won't clear the fuel that is being constantly delivered to the cylinders while cranking.

The ignition distributor should be at it's midpoint in the arc it will swing. Perhaps it was installed a tooth off. All the way clockwise would be advanced (hope that's right). Hook up a timing light and see where it is firing.

Wiring of the CDI unit:

A terminal wire goes to the #15 of the transformer.

B terminal wire is the switched 12 volt input for the CDI.

C terminal wire is connected to the distributor points.

D terminal is ground.

Looking at the CDI connector on the unit, "A" is far left, "B" is center, "C" is far right, "D" is the spade terminal on the housing. Playing with the wire from the distributor to the coil transformer doesn't do any good as there is no direct connection from the distributor to the transformer.
