I have the Wilson spacer that is worth a few horses. I ordered a new power valve. I had to lower the floats after a run in the mountians. The high alltitude and lower air pressure must have distorted a float. I replaced them with the phenolic solid floats. I'm betting it is the power valve too. The new one will be here in a day or 2 and I'll report back. Thanks Yall' Bill 1362
Don't forget to use a power valve "check valve". They do help. The failure rate on the PV's is alarming.
Good move on the solid floats and what JFFR says is very accurate.
The higher altitude will boil the fuel at a lower pressure and temperature.
Phenolitic insulator is all you can do and not to overly alarm you but the Holley needle and seats are crap too?
Make sure that you use a pressure regulator and set it under 7psi. What happens when the fuel "boils" is that pressure in the float bowl increases past the limit of the inlet valves.
At least with the regulator, that won't be true of the inlet pressure available.
...and stop doing those Pike's Peak hill climbs.
The angle is exceeding the limits of the bowl vents and spilling into the engine.
Gee-ze. Kids. Gotta' tell 'em everything?
