Release stuck float valve honda cbr 1988 carb

You may need to completely clean the carb with a carb cleaner. If bike was setting over winter and not started, the old gas breaks down leaving grime on internal carb parts. I understand the gas now-a-days with 10% ethinol breaks down after about 2 months.
A carb kit can be purchased with new parts that can
also help in most cases.

Maxim x turns over, but fuel coming from over flow tube onto floor? After turning over two times, charged battery, I cant even get it to turn over. Any Ideas?? (it just clicks now).

clean ya carb. if it's overflowing make sure you don't have your fuel valve on prime. clean the **** outta your carbs ( pull the jets and run a pice of small wire through each one then blow em out), then do the same for the float needle pieces. pull the float pull the needle and check it's seal then clean teh brass fitting it goes into if still having prob replace float needle. good luck man. ne more questions email me. customsouth676@

We put a new plug in it lasts a couple of days then fails. the plug is not discoloured it just looks wet. The bike is a carb version 08

The carb float level(s) may need to be adjusted. It should be a simple fix with a manual. Read the instructions, and the warnings, then take it apart and fix it. Get a gasket kit, or a rebuild kit for it too, and clean the old gasket material from the surfaces good. There may be instructions in the kit.

Getting gas in breather box/leaks out after shutdown.

I had the same issue, cleaned the gas tank, carbs removed, cleaned and tuned. It helped but still has a rough idle when cold, likely due to a tired float. Best to try cleaning everything first, I had to use a carb guy to get the carbs tuned right for $100 and he remarked on the float not fully functional but I got away with it for a couple seasons. Winterization is essential to keep gas from causing this problem again. Damn ethanol

Fuel leaking from carb vent tube on newly cleaned carburetor

that would be either the float set to high or the needle and seat is missing an o-ring while you had it apart. Should look at getting a carb kit there only approx. 23 bucks and it would save you a lot of grief in the long run.

1985 yamaha Maxim 700 carbs gummed up.

you can leave them together as long as the choke circuits are working. Leave the floats alone, as they are probably set correctly. The little aluminum plugs are for the A/F screws. If you haven't taken them out, then they are still in place. If you have, leave them out as you don't need them. They are for the EPA. If your tank is that bad, find one that is good, and trash the old one. It will save you from having to keep taking the carbs off over and over, then you will have wished you had gotten another tank. If your new float valves don't have a screen, get an inline fuel filter which would be recommended any way. One for a lawn mower should work great.

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 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,
