In an effort to get my carb (stock carb on a '85 Toyota) to run better at angles I set my float level on the low side. I also attached a rubber hose to the vent in the venturi and routed it up and inside the air cleaner. Today I bought a fuel pressure regulator. I've been told a bunch of different setting so try. Some have said 1.5-2.0 psi, while others have said that 2-3 psi works well. I want to run the lowest psi possible without starving the engine. How do I know what the minimum psi is that is safe? I don't want to wreck my engine <IMG SRC="smilies/maggie.gif" border="0"> <IMG SRC="smilies/crybaby2.gif" border="0">.

I have a weber so it's not exactly the same, but I used to run mine at 1.5 and I still had problems on the steep stuff. This last weekend I went to moab and turned it to the minimum 1 psi and this time I had no problem running up the steep slickrock. Best time I've had down there in a long time. I'm not sure if that was the ticket but it sure is a coinkydink. <IMG SRC="smilies/biggrin.gif" border="0">

I just did some testin and I was able to cruise in third gear at 4500 rpm's with the fuel pressure regulator set at 1 psi.

Thanks for the help <IMG SRC="smilies/grinpimp.gif" border="0">.
