choking dual carbs? Options

[last337]

I had a lot of trouble the other day getting my engine to start. I eventually had to enrich each barrel to get it to fire up then lean it out a bit to smooth my idle a bit after it warmed up. Is there a way to choke these carbs initially to prevent this? Is there an easier way to start the engine when cold?

what is your warm engine idle speed? unless your webers have the cold start devices (cable operated), there's no provision for "choking" the webers. the butterfies are pretty much in the closed position at idle. by "enrich each barrel" did you turn the idle speed adjustment screws or the idle air/fuel mixture needle screws? which ever, you shouldn't have to do that.

for a cold engine, dual carbs:
1. turn key to first position so you can hear the pump running.
2. give the gas pedal a few stabs. the pump jets will shoot fine streams of fuel down the throats. priming them.
3. while cranking, just give it a touch of pedal so it catches and manually keep the idle @ 1.5ishk (or less. whatever it takes so the engine doesn't die) rpm and hold it there for a minute or so. release pedal. the idle might be a bit low but should rise in a short period of time.
