I recently bought a 1950 sedan delivery that has been very worked on. Well after bring it home it started to stall on me ( never happened on my test drives of course ) after driving it around for a bit then stopping the car at a light it would stall on me and not start for a bit. The engine is an undetermined BBC with a undetermined Holley. It has a mechanical fuel pump and the lines seem good but the fuel filter is right next to the block don't know if that would cause a problem or not. I think it is a fuel problem or lack there of. Today when it stalled on me I sprayed in engine starter in a can and it started up. The carb's gaskets are leaking a bit so that needs to be rebuild some time. I don't know the carb, settings it has or what jets but I hope to find out soon.
Any info or suggestions would be greatly appreciated!

The stalling issue is likely fuel related.It is either getting too much fuel and flooding out or it starving for fuel and justs quits.The fact you have a hard time getting it started after it dies kinda sounds like flooding out.The fuel filter next to the engine block at the front shouldn't be a problem though.Run both idle mixture screws right in and then turn both back out about 1 1/4 to 1 1/2 turns.Flooding will result in strong exhast stink,black smoke and really crappy (rough)idle.Flooding usually caused by a stiking needle and seat.
It could be the timing is also a tad conservative(big blocks like fairly aggressive initial advance eg.minimum 10-12degrees).I wouldn't get too liberal with that "engine starter can" however or you may end up with a nice big bang and attendant flame.Hate the smell of burning hair.

Just looked at your pictures.Wow, that is one straight looking piece!!!
Based on the general look of your new toy I don't think your problem will be too serious.Was the car being driven regularily much before you bought it or was it just sitting in a garage? If it was just sitting, old gas may have made the needle and seat a bit sticky. The carb is a dual feed type Holley and it will have the side sight plugs for the float bowls.If the needle and seat are sticking when you take out the sight plug ,fuel will just pour out the hole.Usually these carbs do not have any external leaks and if you see gas leaking it makes me all the more suspicious that it's drowning itself.

Thank you BOARDERT, Yes the car wasent driven much before I bought it. I don't know anything about holleys and less about BBC's ( SBC guy ) so this will all be a learning experance for me. The car runs a little bit rugh so I think a tune up would be a good idea. I am trying to track down the block # first so I can correctly address timing.
On a side note the BBC with th700-R4 with 9" 4.11 rear end are sure fun with the sinny little 235 ties graemlins/hurray.gif
