I have done this procedure but my only concern was the advance. I do not have an option for ported vac on this carb and from my understanding it is better to run it like original with manifold vac. Tonight I'll check and see what my advance is at 3k and set her back to 5deg without vac hooked up first

This is exactly what I had thought and why I was having problems deciding what to do. I did not see any option for ported vac on this carb. At the same time it seems to idle good and rev through the rpm but idles a little high around 740 but I can lower it around 640.

Hi guys I know some of this info is in past topics but I have had trouble pin pointing an exact solution. What I have 1959 plymouth 230 flathead 6 *stock* Just upgraded to a Tom Langdon HEI My issue (which might not be an issue) - I set my distributor to 10 degrees advance without vac (tom reccomend 10-15) as soon as I include vac, advance will jump to 35 at idle and increase rpm from 800 to 950ish. This tells me I'm on a manifold vac since its pulling at idle? This was the original hook up for the distributor on the carb. Also if I try to idle down on the carb mix screw it will run rough at around 60rpm. I have ordered a carb rebuild kit also Before we did anything we set the motor to tdc with a micrometer, verified point on balancer, set the distributor in at 0 and adjusted from their. Motor was great compression and oil pressure. Only 24k original miles, verified all valves are free and motor idles at 800 and revs smooth. My questions - What is a good idle rpm -What should my advance be at idle with vac -should I trash the timing light and just drive it till she pings and back off the advance - is there a ported vac option on a carter bbs, or should I keep it full vac like original

I dont think so, it is cracked front to back on the key way

Its a single piece design not the bolt on pulley type. I'd love to post a picture but the file size is to large.

Thanks jerry. I sadly have already tried them. Mine is crack so its not able to be repaired. I sent them a picture of mine but no luck locating one so far

Need some help. I have a 1959 230 in my Plymouth and the harmonic balancer is cracked. I cant find a single picture or info on this balancer. It is a single integrated v belt. Not a bolted on pulley
