Re: RE: Hot Carb
Hi guys--I just went through the whole gambit of carb heat problems too,
seems to go with the car.
Several things I found---
hole in manifold feeding J tube plugged,
ignition timing off, leading to excessive heat,
small ball under the little j tube in crab not there,
and that is where the fuel comes out at, you can see it, if you get it hot
then take top of carb off and wait a few minutes.
Along with all this I made a phenolic spacer 1/2 inch thick rather than the
standard 1/4 spacer. Also had the manifold coated with Jet Hot finish that
seems to keep it slightly cooler, sure looks nice.
Then built a stainless heat shield that has two layers with the stuff you
would wrap exhaust pipes with between the sheetmetal.
Now all is well and I can stop for gas and not have to spend two hours to get
the car started!!
Also put in a four in one engine gauge where the clock was and now know what
the engine temps are:
running hard at 65 mph the oil temp is 200 f and water temp is 160.
Normal town driving or at 55 mph the oil temp is 180 and water temp is 140,
oil pressure is 45 to 50 at high speed and about 30 at idle,
all this is with no water thermostat, no heater and no oil cooler, I took
that out after finding it completely plugged up.
Anyone wanting to see pictures, email me off list--Adios Ken
