Woe is Me: my carbs hate me!

Get the brp kits w bowls.
Mine were 360 list but a friend got them at cost 1/2 price
V6.


Either u tube or the manual.
Scuff the area around the bb and cover w 2 part epoxy.
Not sure why they did that.

Start low speed at 5 turns out.

Lube the timing advance arm w graphite.
It should start to move when the carb pickup cam touches the roller.
The roller is 3/8 wide and has an o ring on top to secure it.
The roller is often missing.

You must have the boat in the water to set initial and final timing and idle speed rpm
or w a test prop in a tub.

Water is best.

Buy a factory manual.
Use the brp zip ties. Not clamps or other zip ties. You will see why.

Do not be ham handed with screws in plastic. Seat gently and 1/8th turn more.

Don't forget the plastic washer under the floats.
Many times these are missing.

Floats level and free.

Run rec 90 if at all possible.

The entire fuel system is rubber/plastic.

Some bump the #1 high speed jet up a step.

Use brp gasket sealer.

Thanks, one and all, for the tips. I ordered the kits and supplies, and will post results in a couple of weeks.

A while back I bought an ultrasonic cleaner from harbor freight. It was pretty cheap and works really well. I’m always surprised how much gunk it’ll shake out of a carb. I bought it because the dunk style carb cleaners are so hard on any plastic. With the ultrasonic it’s just distilled water and a little dish soap.

Good luck

Well, yesterday at 9am I took the first two carbs off the Johnson, and it went pretty well. I replaced them and the motor started right up - so I did the other two as well. By 4:30pm the carbs were back in place, and the motor was running once more. Idled on the muffs at about 800 rpms, which should settle down once I get it in the water for final adjustment.

Interestingly, the idle mixtures screws were all set at 6 3/4 turns - except the top starboard carb, which was set at 8 3/4 turns out. Yikes! Reset them all to 6 1/2 turns for now, then will do the final adjustment once we splash again. Best part - no more fuel leaks! Yay!

Thanks for the support and encouragement from all!

Awesome! I'm so glad it worked out well. Time to get back on the water!
