float neeedles?

[oldyam80sg]

Went to get the bike today to ride. Carbs cleaned this past winter thoroughly,float height set, bread tie sync to get it to where I can ride it. Turned on fuel and bike runs really nice but as soon as fuel is turned on #3 carb leaks-Rapped on float bowl but fuel steadily drips out of bowl. Would the float needles be the cause? Fuel drips after a bit steadily. I have new float needles to put in if need be.

yep sounds like, could be a bit of dirt on the tip. mine did it a few weeks ago, so i drained the float bowl and then turned the fuel tap to prim, the bit of dirt was washed off the tip of the float valve and sealed its self.

Thanks for the reply Tony! I bought new float needles a while ago. Going to take the carbs off and replace it. I was amazed how well the bike sounded after going through the carbs-no carb popping at all. Was able to walk away and make a phone call while the bike was running. Fuel was shut off to carbs 3 and 4.

Tony-could it be the washer in the float seat? T I dont know why it would be a steady stream of fuel.

The '80 and later carbs have an o-ring on the float needle seat and screw and bracket to hold them in. They are sometimes hard to remove on account of corrosion. Once removed the bores can be polished so the new o-ring seals well. Also polish the needle seats.

What do I polish it with Schming? I have replacement O rings as well if I need to replace it.

I take a small brass brush that I have purchased from Harbor Freight. They sell a nice little kit with a variety of different brushes in it. There are steel, brass and plastic brushes in various sizes. Engine Brush Kit, 20 Piece (harborfreight.com). I only use the plastic and brass brushes on the carbs. That a some carb cleaner does the job.

I cut a Q-tip in half stick it in my dremel tool and use a bit of Simichrome polishing compound and clean after with Berrymans B-12 carb cleaner and a fresh Q-tip til you can see yourself looking back at you

So I took off the carbs today and took it so where I can work on them-Moms garage.I removed float bowl # 3 and took out the float needle. It didn't look too bad but replaced it with a new one. The float seat was VERY dirty. It took 3 q tips and was almost black upon initial cleaning. I doint know how I skipped this in my winter cleaning. I put everything back together and after dinner, put the carbs back on the bike. Will start it up tomorrow-weather permitting.

Most have been the dirty float seat. Started the bike today and no leaks. Ran for a while before I shut off the bike.

I always use Mothers Mag Polish and wooden swabs that are used in electronics. Like you said, they come out black and will take a few to polish out to clean shiny brass. That makes the best seal.

I start the bike daily-no issues. I will ride it to my Moms house this weekend. I can't believe how good this runs.
