Question about Honda CBX 750 F Motorcycles
I have a 1978 honda 750 four,it has been sitting a while put in new battery , took carbs off cleaned them, it will start and run on full choke, will not idle? , fresh fuel, fresh oil, mixture screw(s) all four, seated ;backed off two full turns. wont idle after its warm either.where can it **** air from-to need so much fuel?rubber tubes from air filter intacked and the ones to the heads are ok
The stock pilot screw setting is one and one half turns. The usual problem for not idling is that the slow speed circuits in the carbs are still plugged up. Secondary cause is usually that the carbs are not in sync > The carb slides don't all move upward at exactly the same moment. If you haven't installed new spark plugs, do it. Soak the carbs in denatured alcohol after removing the slides and float bowls. Finish with spray carb cleaner and compressed air. Spray into all the drill holes, ( circuits ), in each carb. Install an in-line fuel filter to prevent trash from the gas tank getting into the carbs.
