Been resurrecting my 83 2.4. Sorted out wiring, spark issues and trim. Tried to start today. When I prime the fuel bulb I hear fuel going to carbs with cowling off. Motor wants to run when cranked but can’t. If I pump bulb continuously fuel runs out of top left carb opening. Pull plugs. Bone dry. New plugs. No oil , fuel etc...I am thinking on this motor only thing left could be fuel diaphragm. Have spark on all six. Any other issues cause no fuel to got to cylinders on these motors?
Thanks in advance
Tom
