what would cause gas to come out of the carb choke hole thingy on a 750 holley. Like is comes out at a very high rate... I just put a new motor in and it was TPI before and now its carb, i haven't gotten it to idel yet....i put the mallory fuel reg on it and i haven't been able to mess with it b/c i'm running to shut off the b/c gas is coming out of the hole...also i rebuild the carb myself and i still need to adjust it.

Do i have too much fuel press, or is the carb not adjusted right?

 

the float is hung open. this could be caused by a couple of different things. either there is trash in the needle and seat causing it to hold it open, the needle and seat are messed up/worn out...or you sank the float..that would be caused by a pinhole in the float and it fills up with fuel and sinks.

it could also be caused by too much fuel pressure. do yo have a gauge on it? what is it showing? should be around 4-6psi.

 

Are you talking about the vent tube. If so you may have a piece of trash stuck under the needle seat, do you have and electric pump or manual pump, and are you running a filter?

 

just a filter before the regulator...i think is comeing out of the vent tube i'm no to sure i've never had a carb before...

as for the the needle seat and stuff... how do i adjust them, and where would trash get hung up...

I don't think there is hole in the float b/c it happen the sec fuel got thru the lines, i think i would have taken some time before it fill up the float.

I can't check the press. b/c before i can get over ther it comeing out of the hole already...i'm hopefully going to get someone to sit there a watch it when i get off work...

but untill them thanks again guys i'll check everything out.

 

If you don't have the inlet nut "screens" in place (Holley doesn't call them "filters"), Holley won't honor their warranty.

I have some pics I'll post sometime soon showing why. I had a filter in the line going to the carb, and the "screens" still had junk in them.

 

O.K Try this, take the plastic end of a larger screw driver and whack the adjustment nuts on the bowles, sometimes if a carb sits for a while without gas in it the seat needle will stick because the float is at the bottom putting pressure on the unit and the thing may become sticky, so when the bowl fills up the needle will stick keeping the bowl from rising and cutting the flow of fuel off, try this first I have seen it happen many times and usually will fix it right away, now if its a new carb it may just be you need to set the float level, have you pulled the sight plugs yet.? If not you may also stick a small screw driver in the hole and see if you can move the float if it is still stuck.

 

My carb did the same thing brand new out of the box. Tapped on the bowl and it fixed the problem.

 

Well MYFAST, whats the deal, did that do the trick?

 

THANK YOU !!!!
