Carb question

[loxley007]

Hi, chasing down a carb issue (ok a few carb issues). I’ve done the see through tube float test and no one carb has zero fuel coming out the tube.

I’ve pulled the carbs and no 1 does have fuel in the bowl. Float needle is free, jets are clean. Float height is as the other carbs.

Anyone got any ideas on why carb 1 isn’t getting sufficient fuel?

Would the float height need to be radically different from carbs 2-4? Is there any other reason why the carb might be getting less fuel?

Thanks in advance.

So when you pull the bowl is it full or empty? Also with the bowl off is there plenty of fuel flowing out the needle valve when released? If you have plenty of flow and not enough in the bowl then adjust the float to meet your needs and not worry to much about the measurements.

Cheers, the bowl was full when I pulled it but just checked the height and it was way too high compared to the others. I’m just working on it now and will update.
