Still not getting the floats set right!!!

Postby Cappy » Mon Jul 27, 2015 4:12 pm



Hello, once again. After severe flooding from the #1 carb, I removed the rack,yet again. (I'm getting pretty fast with that now) I removed the seat, filter screen and needle - all are clean and OK. When I blow into the fuel hose, the needle seems to hold just fine with my finger on it. I have set my caliper to 0.827 (21mm) measuring from the lip at the bowl gasket. Where is the needle supposed to be at 21mm and at what point does it fully close? It is my understanding that the needle should just start to move at 21mm. Ive tried putting the carb rack on end, upside down and right side up without any success. When I adjust the float then allow it to move down (as in a run dry condition) the pin falls out or gets stuck in the open position. With your help, I intend to get this right, as there is no one else in my community here in Georgia who know much more about it than I. So again, I thank you in advance.

When you say "the pin falls out or gets stuck in the open position" do you mean the spring loaded plunger on the float valve? If that plunger is falling out, you need a new valve.
Everything else you need to know is here

Thanks, Sprialout. The float valve is falling out of the seat, or moving out so far that it gets misaligned and won't go back in on it's own. I believe the clip is not doing right, as the float valve doesn't have any free play regardless of where the floats are. I'll keep trying. Sometimes it helps just to get an educated opinion like yours. I appreciate it.

Have you set the float stop tab? This is the other little tab on the brass part of the float assembly that is designed to only let the float drop so far to prevent the needle dropping out or the float getting stuck at the bottom if the float bowl is empty. It should stop against the longer metal post that the float pivot pin goes through.

Thanks again. I think, with help from this forum, I've got this float thing figured out. I have cleaned the seat filter, cleaned and polished the inside of the seat, buffed the ribs on the needle with some 2,000 grit paper. It seems to move freely and the tip looks good. I can suck on the fuel line and the needle is seating. When I get home tonight, I intend to put the carb rack on end so the floats are free, then set the tab so that it just touches the plunger tip "WHEN THE NEEDLE IS SEATED BUT THE PLUNGER NOT COMPRESSED". I will also adjust the "stop" tab so the needle can't get too far out to get in a bind. And finally, I dropped the little clip that attaches to the needle, but I read somewhere that it is not particularly needed. So thanks for the advise - I'll get this job done!

Honda would not have made that clip were it not important. Post #36 here has some nice photos and info. http://www.ngwclub.com/forum/viewtopic. ... 2&start=30

Thanks for the link. It has some great pics. You are correct about honda's requirement for the needle clip. I'll try to find it, but I finally have the float set just right. (I hope!)

Nope. Post in the wanted forum, someone's bound to have one.

I've got some somewhere. I'll look when I get back home, and if they don't turn up, I've got a set of junk carbs I can pull one out of if needed.

It doesn't take any visible gum to really make the needle valve stick. I've had good results soaking with lacquer thinner and a q-tip. Just don't let any rubber or plastic get anywhere near the lacquer thinner.

Cappy, I found some clips if you still need one.
