Hello, I have a 1978 Luv, rebuilt 2.0 block, 1.8 head, delta cam, dual valve springs with titanium retainers, a 5 speed Trans and dellorto 45 side draft carb. To run the carb properly, I bought an electric fuel pump that is rated for 3 to 5 psi.
I turned on the truck for the first time but have a problem I haven't figured out. The truck turns on for 10 seconds then dies. It turns back on every time, for about 10 seconds and dies. While it's on I'm able to rev it and it feels good, no hesitations. I bought a banjo for the carb that has a return line and no change. I checked the floats and they are where they are suppose to be. It just seems to run out of gas. I cleaned out the gas tank before turning it on, the carb is rebuilt, gas cap and filter are new. I used a spark plug tester to make sure I wasn't running out of power to the spark plugs some how. That all checked out good.
I've tried getting a hold of ctmandu because he is the only one I've seen here try this combination with no luck. Any suggestions on trouble shooting would be appreciated.
Thank you for your help.
