I have a twin 305 228hp inboard quadrajet that ran beautifully until after almost running out of fuel...refueled...immediately my port engine started "hunting" and had erratic rpms...stalling...I restarted...it starts and runs for a few seconds hunting the whole time...sometimes backfiring through the carburetor and then dies...will not idle. I've done the following:
switched carburetor from good engine to bad...no fix
switched carburetor from bad to good... good engine worked fine with bad engine carb
replaced fuel pump
changed fuel filter
switched fuel line from good engine over to bad engine...no change in bad engine
I am looking for suggestions for what to check next.
Thanks
