76 cyclone 440

Update for all who care,lol. I did figure out what fuel pumps are on my 2 cyclones, they are some mikuni plastic ones made for briggs and straton motors part number 808656 type. I still havnt figured out how to post pics yet so I figured I would just let everyone know whats up so far. So I have put new square type mikuni fuel pump on and new fuel lines,plugs,ect. Checked all wires threw out ect. What I have found is that it is flooding really bad and when I turn the fuel shut off valve off and starts to use up the fuel in crank case and from carb it runs excellent for a few minutes then dies, of course. So I start it again with fuel on and try again, same thing then shut off fuel. Once it starts running great again I turn on fuel then starts flooding again. So it has to be the carb and I went threw it with several times, so my conclusion is its gota be a bad, really bad needle and seat, even though it looks fine. Now my only problem is finding the right one, which is jd part number am53358 for a mikuni vm34-84 carb. So I checked some mikuni numbers on vm carbs and found a vm34/39 needle and seat to be used on a lot of similar carbs but cant find that needle and seat either,just all I find at dennis kirk and so one are different numbers. Anyone know for sure what mikuni number needle and seat it is or where to get?
