Re: Truck deing when choke is pushed all the way in
Lean condition. Like you said, vacuum hose broken or off or a gasket. It's either too much air or not enough gas.
1. Vac leak detection, broken hoses hard to see, also check for loose carb and manifold bolts and gaskets.
2. See if you have a squirt of gas in carb throat
3. Replace all fuel filters.
4. Do a fuel pump flow test.
5. Try with air cleaner OFF
6. Be sure gas tank/gas cap is venting
7. Crappy batch of gas?
8. May need to renew carb guts (esp needle valve) and reset float level and drop. Could be gummy inside carb.
9. Possible accelerator pump leak, not sure about that one yet.
report finding
