What seems to be the prob?Bad hesistation on intial step down?Yes there are several differnt pump cams(diff colors) with more than 1 setting each..also differnt squirter sizes....30 cc or 50 ccc size accel pumps.......fining tuning is required.....

Also DP's have 2 accel pumps....

[shoman1997]

well i pump the gas twice fires right up runs bout ten seconds and dies like it runs out of gas i have fuel pressure gauge says 5 psi all the time

Does this DP have a choke ?And a fast idle circuit?

[shoman1997]

I'd bump the pressure to 6lbs and see what that does. Also is your float level set too low?

[shoman1997]

i had a guy adjust that to where it run out the side and set it there that should be good right ??? ill try to bump to 6 lbs i guess

Actually you want to get it to where it just barely trickles out of the site holes and then drop it just a hair to where it does not come out at all. You should also get you a holley carb tuning book, it will make life alot easier. I think Craig has them at the shop or you could even check one out from the library.
