When I let my car sit for a few days(2 days), it takes a while to start. I have to pump the pedal 15 times and choke it before it thinks about starting. Once it has started it turns over first time the rest of the day.
Any suggestions? Could it be the carb bowl leaking? How can I tell?

Thanks
Harry

Well, if your carb was leaking, it'd likely be all over the manifold. Choking a cold motor will help it start more quickly, but fifteen accelerator pumps? Yikes What carb do you have?

When it finally does light, does it billow smoke out the exhaust? If so, what color?

Changed your ingnition breaker points lately?
For that matter, how long has it been since a tune-up, INCLUDING: fuel & air filter, plugs, points, condenser, cap, rotor, wires, oil & filter...

All this on the assumption that the motor cranks at normal speed (good starter/battery voltage)

It is a Holley 4 barrel carb. The car runs perfect once it starts, no problems at all. I set the timing, dwell(adjusted points, didn't replace), but haven't done anything with the plugs in about year(4000 miles). The rotor is a year old.
When it does finally crank there is no smoke cloud. It seems to crank as soon as it gets enough gas, it isn't flooding. That is what confused me. If I use a squirt of starting fluid it turns right over and runs fine.
Once it has turned once, it starts great the rest of the day. I don't see gas on the intake, but then again I haven't checked after I stopped. I will check that today.
Thanks for the help.

Check those float levels and adjust as necessary. Is that a manual choke carb? Check to see if the choke butterfly valve is in fact closing to spec. You are using a mechanical fuel pump, correct? I'd also suggest a fuel filter. If an early OEM-style pump, you may need a (small) filter wrench to get the canister off, especially if it hasn't been off for a while. Those buggers can be a bear to get turning by hand

I was just out messing with it. I have a standard(original) fuel pump, and one of the clear fuel filters about halfway up the line before the carb that seems fine. I am not sure how to adjust the float, but I will try and find some info on it. The manual choke seems to be fine too.
I checked the timing, dwell and hooked up a tach while I was out there too. The timing was fine, and the dwell was at 24, but the points tested bad. So I am acutally headed out to get a new set along with some oil and a filter(might as well change oil while I am at it). I will let you know.
Thanks for the help.

I dropped new points and condesor in today, and it fired right up.
I will watch it this week after a few days of not driving her, and see how it is.
Thanks
