Carbs and tuning

["Gary H." <62to65mopar@xxxxxxxxxxx>]

I'm posting this mail for Earl H. who is having difficulty with posting 
to Topica (more on this soon). -- Thanks, Gary H.
==================================================

I hope everyone is getting the importance of Don's carb instructions.
I would like to review and perhaps put in order some of his lessons.

Carb's are about venture signal. First, get the timing curve right, our 
motors like a different timing curve than a chevy. Next get the fuel 
pressure right. Then start with the carb. Floats First. Start with the 
factory recommendations. If your messed up, and get it out of whack 
tuning, go back to the factory settings. ALL the settings, primaries, 
secondary, and accelerator pump cam's (Holly), and air/fuel bleed 
settings, needles if Eddy.

Almost all Street Avengers and Eddy's work well out of the box. If you
bolt it on and it is a dog, go back to the first step, first, then the 
carb.

Most Eddy's have the floats set wrong....

Start tuning the primaries, primary accelerator pump, get it driving 
good on the primaries, then start on the secondary side. Most carbs have 
a tuning chart based on your altitude, use it, it will start you in the 
correct direction.

I have recommended this in other post, and members have started with
the factory chart and ended up with good results, and a good 
understanding of how a carb responds to changes.

If you skip timing curve, fuel pressure, and go straight to the carb, 
you get statements like, "It does not work like I expected". Like Don 
said, carbs are not that complicated...
