The only draw back to that design is, what if you are sitting in the truck listening to the radio on a cold day with the engine off? You will be heating the choke coil and it will be difficult to crank. I used an oil pressure switch in series with the ignition to eliminate that problem.
If your radio is wired to the ACC circuit and your choke is wired to the IGN circuit (as they should be) then if you want to listen to the radio the ignition switch should be in the ACC position which takes the IGN circuit off-line. The easiest and best method is to take the choke lead off the coil voltage before any voltage dropping resistors that may be in the circuit.
Second note, I would rather have a holley than any other carb for off road. Not to mention that they are very adaptable to nearly any application (if you know how to tune it properly)
Me too, but most marine units are even better for off-road use - vented into the carb throat and some are designed to reduce the chance of leakage. I certainly agree that a Holley is nearly infinitely tunable - with many parts available.
If you dont know how to tune a holley (and I dont mean just tweaking the screw adjustments) you will not enjoy that carb.
True, but the 2bbl units are much simpler to adjust and tune than the 4bbl models. I've always maintained that the bad thing about a Holley carb is that you have to set it up correctly but the good thing is that you can - provided you take the time to understand it.
