Holley 1904 problems

Having a weird problem.

1904 holley, 200 I6, 2-speed fordo

This is a great little carb; easy to tune, adequate funtionalbility.
Runs great except after a few minutes, when car is at normal operating
temperature, on most left-hand turns carb tries to flood out. I can pat the
gas and once it goes straight it runs very well.

This does not occur on right turns.
What would be the likely culprit:
1. Engine heat causing fuel boiling which lowers fuel supply
(gas inlet is on the right, so fuel in bowl is leaning away from supply)
2. Could actually be starving for fuel (not flooding) float too low.

solutions? Make some sort of heat shield. Adjust float.

Thanks All
 
Unfortunately, my solution was to get the original Autolite 1100 rebuilt and replaced it. I too had issues making hard lefties (or U-turns) and the car basically dying. Thankfully i was pretty profiient at shifting into N real quick and turning the ignition. I will agree with you- its a great little carb, but that issue always annoyed me.
 
Add a inline Fuel Pressue Regulator , they are about 28 bucks at any Autozone , fixed my Falcon when it was all stock with Holley 1brl , it als increased gas mileage, I never got less than 25 ans frequently got 33 ( 62 Sedan Delivery , Recurved Points Dizzy , larger Exhaust aka Maveick 250 Manifold , and 3speed with 320 gears )
 
I would rather make due with the Holley for a while. My 1100 is beyond
repair and/or rebuild. I plan on getting another in the future.

Is the inline fuel regulator a universal item or do I ask for one for
a specific car? If the pressure is adjustable or fixed, what would
it need to be? 2 or 3 psi?
 
Transdapt , Mr Gasket , Dupree all make them , best out there was a brand called Cagel or Cagle , it was Vacuum compensating , Clifford handled them but stopped about 10 years ago , shame it was a good product
 
Thanks alot FalconSedanDelivery, you've been a great help.

Back to my original question.
Is this left turn stalling a result of excessive fuel or fuel starvation?

Thanks
 
The needle and seat are marginal , especially if pressure is a bit high , along with float too high , , with the top part inverted the float seam should be parallel to 1/16 up
 
I have a 1940 that does the same on really hard turns. It doesn't occur often enough for me to worry about, in fact hardly ever. As soon as the car straightens, it kicks back in anyway. If yours is excessive, try raising the float level.

This regulator idea were talking about, I'm familuar with it, but not with how it would help mpg. I'm always trying to gain mpg. Please explain.
 
If the Needle allowing fuel into the bowl only lets it in when its supposed to, the mixture stays where ITS supposed to , and not go rich , it will add up,
 
I just set up 3 Holleys on an Offy 3x1 manifold and setting the float level would have been nearly impossible without glass bowls. None of the carbs I set by factory specs were even close; they all flooded and one carb was a serious pain, but I finally got them all set and it runs good - maybe a little lean, but I'll work on that next. I use a Holley 1-4 lb regulator set at 3 lbs.

"The needle and seat are marginal". A forum member on the Vintage page, noticed that the orifice replacement seats were larger than the original stock one and I think he also mentioned that it was offset. That problem along with those dinky brass floats, different fuel gravity, etc. makes the 40 year old factory setting outdated.

I'd have to lean on float level as the cause of your problem especially if it's running good when you straighten out.
