I have a 1964 Chev truck w/250 6 cyl that I can not keep

Customer Question

I have a 1964 Chev truck w/250 6 cyl that I can not keep running, I started it last week & took it out on the road & in 1 mile it died & I can re start it but it only reeves up an very quickly dies. I have pulled the top off of the CARB & the fuel is real low & a little bit of dirt in the bottom & when I turn it on to see if I have fuel it seems ok with good spurts of fuel. What can I do?

If the fuel in the Fuel Bowl is low, then the Needle Valve is likely stuck or the Fuel Pump has a Internal leak
1) pull Oil dip Stick & smell the oil to be sure there is NO Fuel smell to the Oil
If there is, replace the Fuel Pump
2) pull Carb top & check the Float Bowl & Needle Valve
Be sure there is NO Fuel in the Float
Check Float Level & be sure the Needle Valve closes only when the Float is a little above level
3) be sure there is NO Vacuum Leaks
Check Vacuum Advance Plate & see if the Vacuum Diagphram is holding the Vacuum Advance Plate when full Vacuum is applied

Please continue here, as "Duplicate Questions" are not allowed
The Vacuum Plate of the Distributor holds the Points
This Vacuum Plate "moves" when Vacuum increases with engine RPM
Remove the Distributor Cap
There should be a Arm that goes from the Vacuum Plate to the Vacuum Diagphram on the outside of the Distributor
Disconnect the Vacuum Line & "physically suck" on the line to create Vacuum to the Plate Arm
The Plate should move & hold with Vacuum
NOT ALL Distributors had the Vacuum Plate, so have a look to be sure
