  • Carb leaks
  • Just rebuilt my carb and it now drips fuel from the small hole just in front of the drain plug at the bottom of the carb. How do I correct this? Can't see how to even access this hole. Also what purpose does this hole serve?

  • The rebuild kits have a replacement float valve and seat. The seats are hard to remove and even harder to get all the way in. Are you sure you put the new gasket under the collar of the float seat, and got it screwed down tight?

    Once that is in right, the float should require very little adjustment to be at the correct level.

    If either of those is done wrong, will cause fuel to overflow into the normally dry area where that drain is located.

    The drain is there so we see that there is a problem, and fix it, before all the fuel in the tank ends up in the engine.

  • The carb will leak if it floods. If it didn't leak it would flood into the air intake. The hole is so overflow can leak out. It should have a horse hair strainer in the hole.

  • The venturi will only fit one way if it is supposed to fit in the recess. The flange on the other end is too big to fit in the recess. I do have the 1/4 inch float setting. I did put in the new fuel inlet gizzmo with the rubber tip. Should I try using the old one, as new one has the rubber tip and may not be sealing properly.

  • Look at the part the rubber tip part fits into. It should have a gasket and be screwed down tight. You can try the rubber tip or the steel tip valve. It will not hurt to try.

  • I think you are looking at the other drain orifice, not on early TSX models. Leaking issue maybe a stuck float. Did you insert the Venturi the correct way? Did you set the float to 1/4" from gasket surface with the gasket on? SEE LINK...
