So I am having continual difficulty with trying to get my project GW to run to a point where I can time the engine and tune the carb.
It has a 4 bbl Edlebrock carb (1405) on it that was a mod from the PO. This past weekend I installed a new carb adapter to be sure the seal between the Edlebrock AMC Performance manifold and the carburetor was tight; I inspected and ohm tested all spark plug wires and reconnected wires based on firing order, since I found some that were out of order. I tried starting again and still cannot get the engine to turn over reliably. The carb is getting fuel since I have a new filter and have confirmed the fuel pump operations.
When I use carb starting spray or pour some fuel directly into the carb thru the choke, the engine tries to fire, but just will not seem to run. When I pump gas peddle while engine is choked it almost turns over, but then will eventually blow fire out the carb (since I have the air filter off).
The PO removed much of the emission components, so I have confirmed that many of the ports on the carb are plugged, but not sure how much this would play into getting the engine to turn over. I bought a vacuum tester, but since I cannot get the engine running I cannot use if to test some systems.
Any thoughts on where to go with this, since I am clearly not a mechanic or that familiar with working on carbed engines.
My next step was going to be to pull all plugs (that I replaced with new) to see if there are fouled since I have been repeatedly trying to start engine, indicating an oil issue in the cylinders....
