    Carb Cleaning

    I am cleaning these carbs from a 951 and its been a while since working on a set of carbs and am rather puzzled with this. I am able to blow air and carb cleaner thru everything but on the last carb the" fuel in" plate with the nipple on it seems to be restricted. It will flow carb cleaner thru it but not as quick as I would have thought for the size of the hole. Same with air- it flows but definitely as a slower rate. I have tried to put a fine wire thru but it only goes so far from either side. Is there some sort of a built in restrictor on this side of the carb?

    Are you sure that's the fuel IN? There shouldn't be a restrictor on the IN. However, there is often a restrictor on the return fitting... I can't tell which carb, mag or PTO that came off of (haven't looked at the manual), but if indeed it's the inlet, and you are sure you should make sure you clean it out good. My bet is that the line you are working with is the return or the pulse and it's supposed to be restricted.

    that is the return fitting from the pto carb-- it does have a restrictor in it.
