hi this is dean with his "tired puppy". just got a muffler on the car and it is now quiet enough to talk around. after i got the muffler installed the car stalled at the shop. when the air filter was removed it was found that the carb was filled with gas. i had the shop open up the carb what they said was there was too much pressure comming from the fuel pump. is this possable? the car used to run smooth but now it bucks could this be because they may have adjusted the points also to get it to start? has any one had these problems or have i gotten everything messed up and need to start over again? thanks.

Re: now what!...
Hi Dean,
I think the carb problems are unrelated to the muffler work and the adjustment of the points. While the
fuel pump may have too much pressure, I doubt this if you are running a stock fuel pump. For the pressure
to increase on your stock fuel pump, the dimensions of the parts would need to grow and I don't think their is anything in the gasoline (not even the presence of the alcohol) which is going to make the fuel pump grow into a racing fuel system. I suspect what has happened is the needle and seat is not sealing properly because of wear or some debris has lodged into it.
You should take off your carb, lower the fuel bowl, and disassemble the float area. Clean it out, inspect it, and reassemble it (replace worn/damaged parts as necessary) and attach a hose to the carb inlet. Blow into it and see if you can shut off the air flow by raising and lowering the fuel float.
If this works, attach the fuel line to the carb and see if it fills up the carb bowl and then shuts off.
If you have a pressure gauge, you can measure the fuel pump pressure at the carb. It should be about 4 psi. I believe the flow rate is 1 liter per minute (it is mentioned in the shop manual). You can let it pump into a jar. If you let it run for for 15 seconds, you would have 250 ml or about a little more than a cup (8 oz approx). I think the 1 liter soda bottles say 1 liter is something like 39.8 oz..... so the metric volume is about 10 percent more than the english system.
From what you have described, the problem sounds minor. I have seen the same thing and most of the time a cleaning of the carb and float area has solved the problem most of the time. And the other times, I have needed to change the needle and seat.
good luck,
Dale
