Hey Dave, Sounds like one of the floats stuck open... do you have a mechanical or electrical fuel pump..(electrical pump must shut off)..anyway the pressure in the lines will cause the leaking if the floats are stuck, .. even after its turned off...its probably flooded too.

Hi Holly:
- Remove air filter from top of carb.
- Look down at top of carb
- 2 holes (2 barrel)
- 4 holes (4 barrel)

It sounds like choke heater is not working, if electric test for power if heated by exhaust make sure tubes are clear and hot air is flowing in choke housing. Is the choke butterfly too tight?. May need to adjust tension

I'm not sure, it's been a while but I think it's a 2 barrel. Take the breather off and look down inside the carb. There will be 1 or 2 "holes" going down, these are the barrels.
Putting a larger carb on it will require an adapter plate. I do recall back in the 80's seeing an adapter plate for a 4 barrel for a slant 6. Probably your best bet would be to get in touch with a company like "Summit Racing" and see what they have available.

Sounds like the accelerator pump circuit in the carb is not squirting fuel in when you depress the accelerator. That is why you get the lag in acceleration before it decides to launch. When you open the carb you should get a steady stream of fuel from the accelerator pump. With the engine not running look down the carb throat and open the throttle blades and visually check to see that there is a stream of fuel when doing so. If not time to rebuild the carb, or just get another accelerator pump for
the carb.

Your adjustment is really , really out or your choke is stuck or hooked up wrong. I personally dont suggest that you do the adjusting yourself if your not familiar with carbs due to the fact that it is what feeds your engine the explosive juice it needs to run AND you dont want to have a fire in your engine compartment. But I do suggest that you take it to a person qualified and have it checked out before it dedoes start a fire or other internal damage to your engine. But if you are familiar, reply and I'll walk you thru it.

I suggest carrying around a small screwdriver for this reason... at all times. My 67 stang had this problem in the Straight 6. There are going to be two adjusters, I honestly say just mess with it until you get an adequate response from the motor that you like. (This is for rough, quick, on the fly moments, like being late for work.) Both will need to be messed with in order for you to get the best burn you can.

Sounds like the engine can't breath,
make sure pcv valve is good,or oil cap is vented.
your engine is building up pressure and has no where to vent,so it blows the easiest thing,the dip stick
