my 1920 holley has some issue with the carb, carbs are our weak spot, anyway, when its warmed up and i park it, if its still warm when i try to start it again then gas comes out of the carb, where its coming out is where the float is contained, the little cover that says "holley" above that, there is a rubber piece that is fastened to a little arm,it comes up and gas comes out, same time this happens then the car is flooded, thanks for the help!

Classic case of percolation, commen with Holley 1920's in hot weather. Try dropping the float some (not much). Also, you might want to reroute your fuel line over the valve cover so that it does not go over the water pump and manifolds, where heat will cause expansion of the gas in the line and vaper lock. Some slants don't seem to be affected by this, some are. Mine was, and moving the fuel line solved all my hot start problems (engine flooding), even after driving the crap out of it in 90+ degree heat.

how do i go about doing that? :lol: :oops: :lol: :oops:
i had the carb rebuilt last year, also, replaced all lines from the metal line tothe carb within the last year and they are already routed over the valve cover, but will doublecheck to make sure its not still on the exhaust manifold, thanks alot!

First thing I would adjust your float level, I happen to scan my 1920 sheet from my rebuild.

Oh, that terrible Washington 90 degree heat! :roll:

I'll trade you this 5 months of hot, boiling mud we call an atmosphere here in central GA any day of the week. Up to and sometimes over 100 degrees with accompanying 50 or 60% humidity!

But your points are all well taken, and I'm just jealous cause I love Washington state, and it looks like I'm stuck here in this hell-hole for the long-haul... :(

Bah! eric lives on the west side, i'm over here on the east side of washington, its a huge desert over here.. we have already had a high of 107... People wonder why seattle gets all that rain? because they get there's and our's too... 6inches of rain a year is not nearly enough... So I think eric needs to stop hogging all the rain :P

I'll take a lifetime's worth of hot, dry 107 degree desert days to one mind-numbingly miserable dishwasher 98 degree w/insane humidity day... Be glad that the moisture stays with Eric over on the other side of the Cascades. Perpetual dampness takes it's toll on a lot of things, but cook that wet air up to boiling, and you have the deep south, armpit of the US (that's the tame description! ;) )...

LOL me2...

I spent a few summers down in texas, so I know what you mean...
However... I said that it has already been 107, it get worse arround here... I think the hottest I remember was 117, or 118... at that temp you can't work outside or do anything contructive :P
So 115@10% is just as bad as 100@90% in my book :roll:

:D me too, but its not acting like that anymore, it still acts up some, so i need to work on it a little more, but its nowhere near what it was, thanks to all and the weather is okay here, kinda chilly this morning, but its supposed to warm up some, but not too much, just right for camping, see y'all monday or tuesday!

I beg to differ... I have experienced that kind of heat in Pheonix, and while it's as you say, a useless day, the misery factor just is not there. I compare desert heat to the heat that hits you in the face when you open the oven... wet heat is like the dishwasher. You might think you can do something out of doors, but once you move your muscles for about 1 minute, every pore in your body is pouring sweat and you just have this stuff stuck to you. It's all bad but dry heat just doesn't convey the misery that damp heat does - to each their own :roll: 8)

Now to steer the topic back on course - 1920 Holleys suck! Talk about warpage issues, I have yet to see one that was not a pristine NOS or original example that did not have the bowl so warped that it is practically impossible to seal (a homemade Buna-N rubber gasket (.060") helps)... Particularly prone to distortion is the cheesy zinc die-cast metering plate that screws down to the main body behind the float... Then there is the leak-prone accelerator pump diaphragm... ;)
