I checked out that site ( www.racetep.com ) looking for jets... what is the kit called? Also I'm at a mile above sea level!! Denver, COLORADO what jets should I use for this? I have noticed on some posts that the gasket/s that connects the carb to the manifold should have two holes not just one? what is the difference in performance?
one more thing - my car smells of gas bad. when I get out it makes ME smell like gas.
I'm going to try to upgrade my gas lines to 3/8" that looks like something I need to do.

You will need much smaller jets than Racetep's kit, at least for that altitude. Probably on the order of 125-130 mains, that's my guess. I know from this past weekend (at Pikes Peak), that horsepower is reduced roughly 3% per 1000 ft above sea level, but I'm not sure if there is an equal reduction of fuel required.

I have a 32/36 Weber, just installed and FINALLY got it tuned so it runs pretty good. Now I need to get the most out of it, since it really dogs going up steep hills. I live at 6000ft altitude, what jetting should I look at. Some threads talk about a smaller Main Jet. OGTS told me that the Weber runs with the idle jet about 80 percent of the time..should I look at changing this??

smelling like gas

I have been there...my problem was boiling gas in the bowl.

My clothes smelled like gas,my garage would smell like gas.It was not the
vent lines.Is your car hard to start after sitting from a long drive? could be your gas evaporated.

Even in winter you will boil gas
I used :
1- thick phenolic gasket
2-home made heat shield between the sprint exhaust and intake.
it is fixed!

PS:I have an extra stock heat shield for a stock exhaust ..you can have it for shipping costs..i believe it can be cut to fit the degas 38..but I am not certain.

Thanks on the heat sheild offer! I might hit you up on that... but I think I have the stock one on right now... what's a phenolic gasket?
and yes my car is hard to start after sitting from a long drive. I'm going to take the thing apart this week... check out the heat sheild again.. maybe post a pict...
I get to work and stink like gas... its quite funny I think... but I haffa drive it so the guys at work actually see my project, instead of just hearing about it. and it keeps people out of my cube.

gasket

Chuck;
The phenolic gasket, is more a spacer than a gasket. It's made of a composite material that insulates the carb from the mainfold.

Phenolic Gasket

It seems as though I have the phenolic gasket? I do have a heat sheild as well... I guess I need to check the gas lines - upgrade to 3/8ths?

Really no need to change fuel line size, but would suggest wrapping metal fuel line in 1/4" plastic split wire loom to reduce radiant heat absorbtion.
