smells like gas after acceleration

I noticed it a little last year, but seams to have gotten worse maybe?

My '64 has the original 330 bored 40 over with stock grind cam, rpm intake and 600 edel carb.
I have a pertronics setup under the dizzy cap and an aftermarket coil for it.

I have a fuel regulator and gauge and fuel is pumping to the carb at 4 1/2 to 5 on the gauge.

plugs aren't fowled they have a slight tint to them.

It just smells after I get off the gas after accelerating.
I am going to get a new timing light tomorrow to see where it is sitting.

I do use the stock dual snorkel( it is a 442 after all)with a modifies extra bottom plate. I think that may hurt my performance and thinking about going with a k&n with the cleaner top that is an open element.

I do have the purple edel springs in the rods and my vacuum at 650-700 idle is 17-18.

Any ideas would be great to get me started in the right direction. I don't want to take my kids on a ride and smell gas and or possibly get sick or get a headache..

Thanks

are you still running the carbon canister? the thought of the vapor line/hose that runs vack to the tank could be cracked.
another thought is, does the origional fuel pump come with a return line? and are you running a mechanical or electric fuel pump? what im getting at is if the origional fuel pump had a return line and youve altered that, then maybe the smell is coming from an open return line. other than that, maybe a bad fuel cap? gl finding it

Yeah, this car doesn't have a canister or a return line. The smell does come from the carb after hard acceleration. I am thinking of going through the carb and putting needle and jets back to stock with the yellow step up springs.
Its an edel 1406.

If I try to tune it by a vaccum gauge it states I have late timing.. So when I bring up the timing and adjust the carb i get erratic idle and wore at higher RPMS.

would step up springs let to much fuel in? I do have the stronger springs in. Maybe I'll swap those first..

maybe float set a little too high and it's dumping a small amount of gas somewhere when filling float bowl?? a bad gasket around carb top??
just saying if it is something new,, might be something basic..and you may not have to dig too deep....

I agree, check the float levels.
Raw gas smell indicates a leakage/overflow problem. Id check all your connections, rubber hoses, steel lines, for any loosness or rotting.

I think I got it.. I swapped out the rod and valve and springs. Re-tuned her and took a test drive.. no more surging at cruise and no more smell of gas after hard acceleration...

No idea why I changed springs or rods and valves in the first place..
