Thread: Timing Questions

Tweet

Again, you guys make me proud to be a member of the Club Hot Rod. I'll try to address all of the questions.
DennyW, do not know how to answer your questions about tools/gauges. I am running a mallory pressure regulator set at 7psi. I agree that the idle screws should not be bottomed in.
Selmorides, I have a vaccum gauge and will check the power valve size soon. Good to know what my vaccuum should be, very helpful. I got away from vaccuum secondaries years ago when I had diaphram problems.
Big Truck Driver, I know the 280H has a lumpy idle. I am not trying to eleminate it. Just make it more streetable. Using Sun tach wired to the distributor for rpm readings.
DennyW, There is no doubt that I have limited knowledge, but don't we all?
Thanks for all of this very helpful info. I'll gather some information and get back to you guys. And Big Truck Driver don't worry I always seem to have questions.

Again, this site is great. I'll try to address all the questions.
DennyW, do not know how to answer your question about tools/gauges. I am running a Mallory fuel pressure regulator set to 7 psi. I agree that the idle screws should not be bottomed in. There is no doubt that I have limited knowledge, but then don't we all?
Selmorides, I have a vaccuum gauge and will check power valve size soon. Great information on the vaccuum at idle in gear and the power valve. All of the aftermarket carbs I bought over the years have been for my Vette which is a manual transmission. I got away from vac. sec. carbs years ago when I experienced diaphram problems.
Big Truck Driver, I know that the 280H produces a lumpy idle I am not trying to tune it out, just make it more streetable. I'm using an aftermarket Sunpro tach wired directly to the distributor for my rpm readings.
Thanks for all this very helpful information. This gives me a great starting point. I'll gather some info and get back with you guys.
And Big Truck Driver don't worry I always have questions to ask.

Hey guys, sorry about that. The web site was acting up. Thanks for the help.

Hey Denny, I didn't take it take way. I was just being a smarta--. What psi should I set it to? 6?

Got it. Before installing the regulator I blew straight through the valves flooding out the carb, fouling the plugs. Was told by many 7psi. Never realized it was fuel line size that determined the pressure.
