The power valve/power piston/whatever-da-hale-you-wanna-call-it was worn out in my 318's 2 bbl holley carb.

No hesitation/bog/stumble now!

yayyyyy.

Those darm whatchamacallits will get you every time..

did you replace the carb or the power piston doohicky?

what did you do to fix it in other words?

nice to get updates for ?s. did you go 4-v?

spill the beans..

Glad you found the problem, I`ve been having problems with my D 150 for awhile now it would just stop running and when I race it it would start missing at high rpms, I changed plugs, plug wires , cap and rotor, gas filter, I even put the stock computer back in and still had the same problem. Well today I went to take it out of the trailer ( its winter resting spot) to take it to a body shop to get an estimate on some touch up work and it wouldn`t stay running, it would start run awhile then shut off again, then be hard starting. Years ago I put in an Accel coil I decided to put the stock coil back in to see what would happen, Well it started right up and the miss went away, anybody else have a problem with these coils?

I fixed my buddys truck that had problem with an accel coil one time. he had a points style coil on the stock elect.dist/ecu system. gave it a very weak spark and ran ruff all the time.

I fixed it with his stock coil he removed from the truck.

I now have that free accel coil on my points dist in the 88-440 truck.

Hummmmm, Iv been running my stock coil with my NSD 6. I wonder if I should upgrade to a Blaster coil..

Years ago I lost 2 Accel coils within a couple of months of each other. I put back on a regular coil and have never felt the need for another Accel coil since. Gene

I would like more information on just what you did to fix the problem with your truck. I have had a similar problem with my 86 318 since I got it in 2005. I just figured it was part of the Carter BBD/Holley 2BBL curse. I've owned several 318's during the past 30 years and they have all had that stumble/hesitation. I hate those $*#@&! carbs! Eliminating the computer on my truck helped a little, but it still bogs down. If I had the money, I would throw a 4bbl on it in a heartbeat.
