Engine temp, fans, etc.

Installed the 6 blade HD steel fan with fixed blades. It made a difference right away! Car ran tonite at 175*, never went over 185* at idle or stop lites. Will have to test during the day to see how it is in the heat, but it is looking good. Planning on checking curve in distributor and carb jetting to get it really dailed in. May even get a thinner spacer to bring the fan back 1/2" more to increase air flow. Many thanks to all who took the time to share their thoughts. I'll keep you posted. Tom

Well, another day another problem. Broke my a** to get home for a local cruise nite hoping to drive my "cool" running sled to the gathering. Didn't get 5 miles and it went totally bonkers. Starting missing and bucking and acted like it was starved for gas. Then it started to diesel when I came to a stop and finally I pulled over and it quit. Plenty of spark but the gas wouldn't keep pumping. If you pumped the carb manually and just hit the key it would start and then die. Thought it was vapor locked and removed the tank cap. Finally it started again and I got it back home. Ran so-so at highway speeds and then would buck and diesel at the stops. Got it to the garage and parked it. Hard time getting it started again but finally it went. Checked timing and set idle mixture and idle speed. But something just isn't right, I feel like it is fuel but I can't be sure. Well I'm running on like the motor so I'll leave it here. Any input is welcome. TW

Sounds like a vent hole on the gas tank cap may be closed up. Try leaving it loose and put a shop rag between the deck lid and the actual gas cap to keep it from coming off completely. Then drive it easy for a while and see if that makes any difference.

Be sure to blow out the overflow drain line from the gas tank rubber boot that goes down to the ground just in cast any may slosh out. Unless your tank is totally full you will not even loose any as long as you don't do a hard launch.

This will point you in the right direction.

Also check out the fuel pump to see if the fuel lines or the pump it self, is too close to tube headers (if you have them).

It sounds like you are boiling your fuel. Now all you have to do is figgure out how?

Good luck.

I think I found a major part of the problem. It appears that the heat riser is not functioning properly. When the engine warms up it doesn't open (didn't check this until yesterday).The excessive heat from the exhaust really gets the intake manifold and pass side head very hot. I wired the flapper open and tried to get the car started again, but no luck. Guessing that the heat has cooked the intake manifold gaskets and this creates a huge vacuum leak. Checked all other components carb, fuel pump, coil, distributor. It just seems like the only place left to go.

Sure hope it didn't cook the "Head Gaskets"....! You might give a look at the gaskets under your Carb then if it has been that hot.

Sounds like you are on the right track.

Good Luck

Doing the basics before I start tearing things apart. Took a compression test tonite 175-180 in all cylinders, put in a fresh set of plugs. It fires and runs for a second while you crank it but then quits when you let off the key. Now I, m thinking that Crane electronic system might be acting up??? Next step will be to throw in a points distributor and see what happens. And the beat goes on.......TW

FIXED!!!!!! Coil resistor wire was N/G reapired and it runs. Will now reinstall original carb, check all fluids, clean her up and load in the box for Atlanta. Hopefully this is it.......
