Hey Mike & Luis;

Maybe your knowledge will help with this one?

Drove the Beast for about 250 miles over the weekend, you know you break it in kind of thing.

Had to stop about every 30-40 miles and make some tweaking to the Holley thingie.

The problem is that when I come to a stop the engine quits unless I hit the gas pedal quickly and then it idles back to 1000rpm. I can live with the high idle i.e. 950-1000rpm. But what the hell is going on with this dead spot?

All rats nest removed.

Timing-Right on.

New everything Brand New- (Of Course)

Kinda of lost on this one.

Any ideas???

P.S. I'm out of town a lot so take your time to answer ???????

if its a bridge port it should be idling higher like 1300-1500rpms.

either that or maybe the idle mixture is a little too rich/lean

Hi Mike;

Now thats what I call fast thinkin!

Bin there and done that about 10 times.

What about the float levels?

That is the only thing that I have yet to check.

Do I not only check the Prime or do I check the Seconds also?

Thanks again.

i guess it could be the float levels too, well efi engines will do this same thing and it seems that when you are decelerating and ou put the clutch in the engine will die unless it gets a little extra squirt of gas. it sounds like your problem is similar?



mike

Make sure your high idles is around 1300 and low idle is around 1000 then go from there.I say those idle levels seeing that your engine is bridgeported and getting ready to kick some serious ass.Have you checked your timing with a Timing light????It should be advanced just a couple of degress to compensate for the port job.Does it idle smooth???

Good Morning Mike & Luis;

2 ???'s

Not sure what you means by the High and Low idle Levels. Are you talking about Float levels or what?

As per the Timing issue. Yes I set the Machine up with a Light 2% advanced from stock.

I ordered a Liquid Filled Fuel Pressure Gauge on Tuesday and should be rec'd today. I have a mech one on there now and it could be off. Never have trusted them before and hopefully it's that simple.

When you state running Idle RPM's at 1300 aren't you getting false timing readings???

Thanks

the bp motors need to idle a little higher, like 1300



mike

No,Some carbs have two settings for when the engine is warming up and when the engine is warmed up.My 83's dellorto has to settings on it like that too.My high idle is 1300 and when it warms up I kick it down to 800.Runs beautifully.I'd still sell the carb if I got the right offer on it tho.Then buy a holley setup.

I have to agree with mike about 1300 rpm idle on yours too.Mike is the man. :bigthumg:
