Random overflow from carbs.....

Hi,

I've noticed recently that sometimes when i stop some carbs start (really random... sometime it can be without leaking for weeks then one day one start to drip but will be ok at the next engine stop) to overflow into the intake but otherwise okay prior to riding.

The carb has been freshly rebuilded last week. Float level is okay also. (did the clear tube test)

Prior mounting the carb rack i did a 24 hour test with gas tank on Prime and let the carb with gas inside to see if one is gonna drip gas or not with time.... everything was perfect!

This is more prone to happen when the engine is very hot (hard ride, long stop ,etc)...

Did someone put a curse on my carbs ? If no :laugh:, what can be the cause of all this random mess?

thank you,
laurent

Did you over look to install a good in line fuel filter?
Did you just clean or put kits with new needle and seats?

Good idea, I will check for a fuel filter especially there are cheap.

Cleaned thoroughly and install 4 new rebuild kit with jets and needle valve / seats.

OK, so what I would do is to put in the fuel filter, then turn your petcock off. Loosen and drain all of the fuel out of the bowl drain screws. Then turn the petcock back on and let it run for a minute, while taking a screw driver handle and gently taping on the float bowls. This should rinse out any small debris that might be on a float needle.

Also, when you replace the needles and seats, if they are not exactly like the ones that came out, the fuel level may be set differently. It's always a good idea to check that the operating level is correct.

The manual will have those specs.
