frightening day

[Gaz64]

Hi Jon,

A few things to check are:

Are all the floats levels correct as per IDA procedures?

Were the fuel lines flushed are assembly PRIOR to fitting to the carbs?

Fuel line debris could be preventing a needle and seat from closing correctly.

What fuel pump are you using?

Do you have a fuel pressure regulator?

What pressure do you have it set at?

In answer to questions-
1-yes, did set the floats twice and I think they are o.k.
2-Didn't flush lines but did check and blow out jet openings to check for a prior problem. I did do some clean up to the ends of my lines .I'm using cloth bound lines for the period look but with the teflon liners. Debris from that might be the culprit.
3-120 gal mechanical pump with a Holly pressure reg. right behind it set to just under 3#.

I'm over the total frustration at this point and will open up all the carbs today. I can only assume that this has to do with the main circuit but , as you said, Gaz64, something is keeping the needle valve open-debris or just sticking. I'll report back about what I find. Thanks, Jon

btw- have many of you had success with the spacers under the carbs to cool them a bit? I seem to read spotty reports here on the forum.

webers do take sometime to get sorted out, but totally worth it.
2.5 lbs of fuel pressure
make sure voltage regulator is working right (electric fuel pump)
clean out jets
38 degs full advance on timing

trash in the line is common with a new build. Phenolic adapters didn't do much
on mine. Getting the timing right cooled things down.
