1939 ford skipping
Guys, my 1939 ford with 59AB engine skips from idle up to about 1200-1400 RPM where it smooths out and runs great. I've gone through the distributor, set points, and changed cap and rotor. What next?
TIA Richard |

Re: 1939 ford skipping
At idle, do the idle adjust screws affect rpm as you close them, and if so, are they set about a quarter to half turn open from where closing them causes rpm to fall off? If no effect, check float level and integrity of the power valve.

Re: 1939 ford skipping
Check the accelerator pump and make sure it shoots a good stream of gas when activated.

Re: 1939 ford skipping
Richard. If it skips, it's happy, just like playing hopscotch. LOL Like all us old folks it just takes a little to get us going. How are you doing old friend? Still fooling with Jeeps? Lawson.

Re: 1939 ford skipping
just a thought get some auto start [ether] and spray lightly around throttle shafts sounds like they could be leaking[ the ether will cause a change in idle]
