Hot engine hard to re-start Vapor Lock???

[charles roybal]

"Heat Soak" issues....carb is getting hot from transfer of heat from motor boiling gas and dumping into motor. I had this issue...wooden carb spacer solved this problem.

Hi Charles:
This is what everyone is telling me I will order the spacer. Any difference between phenolic and wood? I had phenolic before and it is great. Tks for your insight.
Cheers

I was told wood is best insulator...I am very pleased..best $27.00 I have ever spent...found mine on Jegg. shttp://www.jegs.com/p/Edelbrock/Edelbrock-Carburetor-Spacers-Wood-Design/743637/10002/-1

Lou, what I meant was, when a problem exists..do the basics first before going off on perhaps the wrong course. Gas supply, Ignition timing, Starter, voltage drop etc. Just make sure everything is where it should be. Sometimes a simple adjustment is all you need.
On my car I solved a ton of heat issues when I installed the ford Taurus 2-speed fan, now it runs cooler all the time and I can control heat spikes using the hi-speed portion of the fan.
Good luck, Bill

All good recomendations and 1 other to consider is what kind of gas are you putting in it. Try to stay away from gas with methanol blend in it. Methanol is alcohol and boils at a much lower temperature then gas without it. I'm running a 496 all aluminum FE with Quick Fuel 850 and can not run a spacer. When I was at Texas Cobra meet this spring temps were low 90s and my car was fine until I put some gas in it up in Austin at a Shell station. Methanol blend and a bunch of us got it and had your concern until we put some high octane fuel in. I bought two 5 gallon jugs of 107 octane fuel and put 5 gallons in it and no more concern. Had the car out a few time since in 90 plus and again no issues....so check that fuel station you are filling up at.

Hi Gary:
Well I use Gulf 93 and I put some octane booster, about the methanol, there is not much choice up here in the NE just about every gas available has 10% methanol.
I thought about possible water in the gas but that would have affected my other three cars and nothing they are fine.
I will keep a more aware eye on this tks man.

Hi Bill:
Oh I know, I removed the faulty gas pressure regulator which had no business being there to begin with; I have a mecahnical gas pump. The venting of the tank was verified, the in line filter was changed, the timng was verified, the starter is high torque brand new and heat shileded, the battery is fine no voltage drop. Now that removed the gas preas. regulator the car runs much better, however, you can feel the heat from the engine which could cause the vapor lock. After a while it starts fine though. I appreciate your input though. tks man

I'm fighting the same issue on my 428 FE.

Going to install a 1/2" wood spacer as mentioned before as well as swap out my mechanical pump for an electric pump.

As far as spacers go wood is best, phenolic resin in next, with the aluminum ones being a distant last.

Perhaps it is the starter. I was having trouble restarting the car after it was hot and turnd out the starter was going out. Probably does not help having that hot exhaust next to it. The replacement has a thermal blanket form DEI on it so hopefully this one wil llast more than 3 years.
Good luck,
Richard

Do you have your battery mounted in trunk? You may need larger battery cable..common problem.
