Re: Hard to start when hot
You could try an elec fuel pump just to "prime" it before trying to start..............

Re: Hard to start when hot
Took off my new bob drake distributor cap to find the NOS Champion rotor had collided with one of the contacts because the BOB drake cap is not the same size, also the brand new bob drake distributor rotor will not turn inside any crab distributor I have because its 2mm to long on the brass end, the bob drake cap and rotor together and you cannot even get the cap on.
Also the new bob drake distributor cap has 2 holes burnt in the side next to the contacts on opposite sides, button in the top has no burning |

Re: Hard to start when hot
I had the same problem with a 38 24 stud with dual 97s. I run only in the warm weather. I blocked the heat riser with core plugs and installed about 5 gaskets under each carb, Problem solved.

Re: Hard to start when hot
I had similar problem on two different engines.........turned out to be the coil on both even though one coil was brand new. Good luck!

and ones sold new work great when cold. The problem is they ALL leak voltage in the windings. The varnish on the wire and the paper between layers of wire did not take the heat that the modern poly type coatings and the treated paper made today by DuPont. Skip uses these modern methods and materials and his coils don't fail and start under high heat conditions. He has rebuilt over 25,000 old Ford coils over the past 25 years with very few failures and he replaced those few at no charge. Along with the coil you need a good ignition switch and a good condenser. We found an IH-200 condenser to work real good. The contacts on the ignition switch are 3 little round balls that wipe on the brass pads in the switch. Clean these pads with 600 sand paper on flat surface so they are smooth. Stand the balls of the switch on 600 paper and put little flats on the bottoms of the balls so they make better contact. Spring the balls down a little to get better contact with the brass pads. A good original type resistor is best. G.M.

Re: Hard to start when hot
With modern fuel you won't get a ping, octane is to high (my opinion). Octane in the 40's is about 40-60. Gas is cheap, go do some burn outs, just don't hangout with people quite yet. Wear gloves at the pumps and take some precaution. Time will tell, but always good to be prepared.

Re: Hard to start when hot
With some electronic module's if the coil doesn't have enough resistance it will blow the coil and burn any plastic components

I work from home for the last 18yrs. I'm used to be being "isolated". Started the 38 up today. Started up after a little bottle prime after a 4 month sleep. Sounded great. If it ever warms up here I'll take it for a cruise. Won't stop to hangout. Some people can't help themselves. Went out on a drive in the f150 last week and saw a friend and stopped to say hello. 10 ft apart. He started creeping from 10ft to 5ft. Had to go. Hope you get it figured out. Have a little recore radiator issue showing up again. Might have a new issue to deal with. Might have to learn and prefect my brazing skills. . Last edited by Tinker; 04-19-2020 at 11:30 PM. |

Re: Hard to start when hot
Yes I could do it if you road test it and it doesn't perform as you wish I could look at it Ted

Re: Hard to start when hot
I found the problem, was a worn out ignition switch, the weight of the keys swing on it caused it to misfire and when I was trying to start it it sometimes if I held the Jew to the left wile cranking it wouldn’t go, put a new ignition switch in and it starts easy, I don’t have to grind on the starter at all anymore when it’s hot.

Re: Hard to start when hot
I had one like that. Turned out to be gas dripping into the manifold.
Took a few seconds of cranking over when it was hot with pedal floored. When it started I didn’t see a cloud. Did find ver short crack in the carb float bowl. A different carb cured it. |

Make sure your gas tank cap is venting

Re: Hard to start when hot
I had the same issue with my 33 tried everything no luck.
If I opened the throttle a bit it would fire up a bit rich though. I lowered the float (single Carby) below what was recommended by 1mm. End of issue it now starts up hot or cold on the first revolution. Kpar |
