carb guysplease help

I took the carb off my super h and put it on my M.It acts the same way on the m as on the super h. load jet dosent work, no diffrence if open pr closed same as on the super h and M.Where is the load circut located in these carbs? i blew it out 3 times now im gonna let it sit in carb cleener for a few days. just wondering wjat aera to hone in on. thanks

The load (“main”) metering circuit is behind the main mixture screw, the adjusting screw at the bottom of the bowl that faces the front of the tractor.

After separating the float bowl from the throttle body casting, remove the main mixture screw and packing nut, then unscrew the main mixture seat from inside the bowl. Also remove the main discharge nozzle plug (flat-head brass plug with a screwdriver slot at the bottom of the bowl) and the main discharge jet (unscrew from the top of the carb through the air passage).

Soak everything overnight, then clean the parts of every trace of dirt, varnish etc. Pay close attention to the floor of the float bowl – often there’s a layer of “mud” that needs to dug/scraped out. If memory serves there's a small hole (or maybe 2?) in the area of the main needle seat in the floor of the bowl - make sure it is clear also. Then thoroughly blow out all the passages in the bowl casting.

Now put it all back together. Check check/reset the float level if required before putting attaching the float bowl to the throttle body. Finally open both idle and main needles 1 turn off their seats to get started.

Good luck!

If you didn't know where it was, how could you possibly blow it out?

tom. I took the carb apart and blew out all the ports and holes. I just wanted to know where i should put my effort to. Thanks for asking though.

I think you are out of your comfort zone here. Send the carb to Rustyfarmall for a rebuild. I've got one new SH carb but it;s got my great Grandson's name on it. (Whatever name he gets)

Checking and setting the float level and checking for leaks is easier if one uses set up as in the link provided.
