Sputter/cut out at high RPM, is it the distributor? Options

[Groosh]

Happy Thanksgiving!

I'm getting a cut out at higher RPMs but it pulls well. I currently run Hot Spark on the original dizzy and the fuel pressure is solid.

I have oiled the distributor with some results but before I go buy a new one, I wondered if there is something else I might try.

Yes Tim_ND helped me. The timing light showed the cut out. I put it on each spark plug wire and all 4 cut out.

Go to the hot spark web site. They have documents and tests. It seems to be voltage that got me. Guess it is heat from voltage. I bought their coil and their ballast resistor. I still got over 14 volts. They want under 13.7. I got a 5 ohm br at napa. Slightly better voltage readings at high rpm, but not idle. Still 14. Put their br and the napa in series and still have too high voltage at 950 rpm.

I have just left it with the new coil, new hot spark and the napa BR. And a spare hot spark in my trunk. The 1st hs module made it 38000 miles. during that time i did replace the voltage regulator. Did not know i should check the HS voltage. The HS comes with a pack of the cool goo stuff. Did you install it under the HS?

Iam not much help. Good luck.
