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. |

Here's the pic I posted in post 9.
http://www.bob2000.com/acccheck.jpg Do you see the blind hole at 11 o'clock in the right hand bowl? That's where the pump chamber vent used to be, but obviously Holley isn't doing it anymore. The rubbish on the other forum would do nothing if the hole is there as he claims. Both of the holes under the umbrella are inlets to the pump chamber. Cutting a groove joining a .013 hole to a .100 hole just going to reduce pump shot further than what you already have since more will bleed back to bowl. The size of the bleed is a balancing act. No bleed gives full pump shot but no venting. I probably wouldn't exceed .020. |
For what ever reason he apparently decided to grind a groove back to the feed hole under the umbrella seal - instead of drilling out the auxiliary vent hole. Not sure I buy into that either. Prefer to get the temperature of the accelerator pump cover down a few degrees in hopes of keeping fuel in it below it's vapor level. It may only take lowering it a few degrees to make a difference.

eI bought a couple of Mr. Gasket carb insulator kits with the aluminum heat shield and worked today on trimming them to fit around all the stuff on this low riser dual 4bbl intake and the carb vacuum secondary linkage.

I plan to leave out one aluminum plate and corresponding gasket when I install it. Hopefully the rain will cooperate tomorrow and I can try it out. |
Looks great.
You should only need one gasket on either side of each heat shield. Don't know why Mr Gasket gives you all that extra stuff. |
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.
