1971 85HP OB chrysler, will not start on its own, unless i spray gas into the carbs then it runs great, i can turn it off & it will start, but when i let it sit for awhile it will not start on its own again, cleaned carbs, need help thanks, jack
I would advise that you refrain from running the engine until you have fixed the problem. Or, you may run the engine lean and ruin the motor.
The problem may be a fuel pump that is going bad, a vacuum leak somewhere in the fuel line or one or more carbs that need to be cleaning or adjusting. I would start by going thru the entire fuel system from fuel tanks, fuel lines, all fuel line connections, fuel pump diaphram and it's check valves and the vacuum line that primes the fuel pump [if it applies]. Sticky float/s in the carb/s and/or incorrect float adjustment.
hey matthew, thanks for yor fast reply, i`ll try that, im also thinking of the fuel going bad, it just runs to good after it starts, so might not picking up enough fuel to start, thanks again, jack
