I`m looking at any and every possibility to explain the 99 jets in this thing. I did have rubber extensions and now I tied the two together with a long slit 1/8th wide in the BOTTOM of the bend so it clears the air filter top/scoop.
with the air cleaner on it normally wouldn't be an issue. and you don't want the slit on the bottom since the incoming air (to the carb) could potentially create a siphon effect on it. without the air cleaner on is when you would normally see a problem, mostly at high speed from the air rushing into the scoop and over the vent tubes. that's when a tube connecting the vents and a narrow slit on the top or side side might help.

Same here, and if the float sticks is less likely to burn your car up, and it dumps into the carb. Not good for the cylinders, but it's the lesser of evils I think.

I'm sure that looks better but if you needed more vertical column you would have to loop it up, the loop has about 4" more vertical column

Dom, is your scoop sealed, if so you wont see a vacumn in the scoop area, specially on top end, that area will be under a slight pressure, about 5"-8" of water at your speed. The loop tube is for a hard leaving car, when you launch the fuel sloshes up and out of the vent falling into the carb causing the carb to go dog rich EDIT also a set up that didnt have a air cleaner and usually no hood, the air passing over the carb would suck fuel out of the vents and spray on the windshield

Lots of ideas here.........I don`t know all of the specs on these metering blocks as far as the holes you mention but I`m taking the carb apart to fully clean and re jet so I`ll check. My carb is sealed to the scoop and actually picks up 1 mph and a bit of et w/out the air filter so that`s how I race it. Thankxx guys.
