If you have set the float properly and the carb is clean, other than changing the air filter and cleaning the intake tract I would pull the gas tank, dump the fuel and remove the petc0ck - there is a small filter on it that should be cleaned or at least checked. Fill it with fresh fuel.

Other than that - you should be good to go! Good luck!!

hi,sounds like the float in the carb is stuck in the fully open position,you will have to take the carb out,take the bowl off the bottom of the carb and inspect the float needle assembly,the little clip that holds the float to the needle valve may have come off,allowing fuel to run unchecked into the carb and ultimately out through the overflow..hope this helps..cheers

I need to reset the float levels in my carbys to stop the overflow on my 1974 Z1A Kawasaki


You describe a problem with either the float or the float-needle and seat. If the needle is not seating then the gas flows past it. If the float has a pin-hole leak, then it will fill with gas and sink.
On some bikes you can remove the carb bowl without removing the carbs. If so, slide the hinge pin holding the float to one side and remove. The float will drop straight down. Catch the needle since it is now loose. Unscrew the needle seat with a socket.
Clean all metal parts in carburator cleaner...do not get carb cleaner on any rubber part. Shake the float and listen for gas inside or see if it floats in water.
Test the needle seal in the seat by blowing gently thru seat. Needle must seat completly with very little pressure holding the needle in the seat.
Re-assemble with new bowl gasket if damaged. A carb rebuild kit ($35) might be available for 1973 carb and contains all new parts instead of cleaning. Kit might even contain new float and float adjust guide.
Avoid adjusting float level if re-using the old float. If using new float, temporarily install old and measure distance to carb body. Install new and match this measuremnt. Bend tang to adjust.

Good luck,
Techjoel

Leaky carb


Here's the deal. The only way gas can be leaking out the carb is because of a float problem. Only six things can create the problem.
  • Gas is getting into the float and is stopping it from actually floating.
  • The rebuiler forgot to put the float needle back into the carb.
  • the rebuilder bent the float level adjustment tang far enough out of range that the needle valve can't close.
  • Many floats have a needle retainer clip that actually holds the needle loosely to the adjusting tang. If the clip was lost the needle can jam at an angle and not be able to close.
  • The rebuilder left out the float mounting pin or the pin is bent or not installed correctly. The float must be loose on the pin once the assembly is in place.
  • The rebuilder left out the float mechanism entirely. This is not very likely.
It might be possible that the mainjet or mainjet 'O' ring was left out and that might cause the problem. I have never seen this before but I just want to cover all, ( even remote ), possibilities.

You paid for the rebuild so I would take the carb back to the rebuilder. You might want to call a Honda dealer's parts department and ask if the parts diagram for the carb shows a float needle retainer clip. Also ask the cost of a " carb kit " Now. if the rebuilder says there is no clip on that carb, you can argue the point.

I wish I could be there with you. Get your money back for the "rebuild" ( less the cost of the carb kit ), and have the dealership fix it. I really want to know what you find out on this problem. Please post a comment on the results.

Please rate this answer after the problem is found. Thanks Chris.

Gas leaking out of a 1983 cordoba top of carburetor


Did the carb kit come with a new float? It sounds like the float level is not set right, it has a hole in it or the needle is not seating right. If the float is not set correctly it will hit on the carb body before it shuts off the fuel flow with the needle and seat. If the float has a hole in it it will fill with fuel and not float at the proper angle to shut the fuel off when the desired level is reached. Remove the top of the carb and inspect the float when closed it should be just about level with the top plate from the carb. Shake the float and see if you hear any liquid in the float. Also are you running a mechanical or electric pump? Mike
P.S. I myself have forgotten to install the needle in a carb rebuild.

Let me know how you make out.
