Carburetor Adjustment Tool

[helojocky]

I recently purchased a 1978 CB750K. It has not run for some time, so I intend to take off the carbs, disassemble them and clean them in an ultrasonic cleaner.

My question is this. After rebuilding and reinstalling, do I need the long carburetor adjusting tool that has the coaxial long shank screwdriver to adjust them.

Thanks in advance for your response and any tricks you may have.

If your mixture screws are under the carbs in front of the float bowls you will need it to fine tune mixture

I am able to reach them , just . It isnt easy and you have to swap hands on different carbs due to the overflow hoses and even which side is which . I also had to make a small screw driver that I could hold under there and be able to turn , but it was doable . I even painted one side white so I could count the turns easier . When I rebuilt my 77 F2 the jetting didnt work and it took me quite a bit of time to get the mixture right . I have an 836 with the std airbox and an open delkevic 4 into 1 pipe and ended up using the std pilot air jet ( 35 ) and two and a quarter turns out on the fuel screw . Trouble is once it gets hot , you dont want to put your hand in there , so I was setting , testing and then waiting for it to cool . Just watch when you do your carb clean . Make sure you use air or carb cleaner to blow out the air/fuel passageways afterwards as ultrasound can leave residue in them . I always bench test the accel pump/squirters before fitting , just in case . Have fun
