thats not low enough. You can go a lot lower without ANY danger of draining the float bowls, especially if you install some main jet extensions with. the notched nytrofil floats. Even w'o that set up you can go lower on the fuel level.

Your engine will run better, and not run rich around a fast corner when you lower the fuel level some more.

I'll repeat what I said recently here, I'ver been working on Holley carbs attached to Ford engines for over 50 years. I haven't seen one yet that didn't run better with the floats lowered from the Holley specs. position. Don't take my word for it, try it and see,

Dan, Occam's razor being what it is I'd try what Tom was talking about. He's dealt with more heat/carb issues than most here because he's a little off center in his mountain motor builds. I'd try a tank of good marine gas (no alcohol) before I went to too much more trouble.

Hey Tom,

[DanEC]

Unfortunately I haven't found any non-ethanol gas around here except regular (no premium). My car would probably be OK on regular since it's an iron head 9.0 compression motor, but I might have to pull a degree or two out of the timing I have in it. I can get race gas about 10 miles from here but the cost seems wasted on a fairly mild motor.

Airport? Marina? Nothing?

Of course you'd have to tell them that it was for something other than a road car.

The reason mr gasket gives you all those layers is because when installed all together the layers of aluminum and gaskets act as a heat sink thus helping to dissipate the heat from the heat sorce.
Much like the aluminum fins on a motorcycle engine.

Finished installing but going to have to wait for the weather to dry up to test it out. I decided to use a regular gasket below the plate and my 3/16 inch composite insulator gasket above. The 3/16 inch gaskets have bolt reinforcements to help control compression and tightening the base plate bolts which I like. If I put another aluminum spacer and gasket in the stack I would be down to about 3/16 inch clearance from the hood to my air cleaner acorn nut so I'm going to try it this way first.







Not much to see from the passenger side.
