Hi mower nerds, I repaired my 2 stroke mower, I think its a v40 or Vortex.

I replaced almost everything, all 'O' ring seals, carby intake manifold inner and outer seals. Crank-puller seal, bottom & top crankshaft bearing.

Now the problem I am having is that its running too rich, too much fuel is going through the carby, drowning the motor. I positioned the white poppet valve on C pointing to the spray hole. Problem remains, tried it on A position, same problem. I compared two plastic carbs, one is off a mustang and the other is the standard that came with the mower. I put the mustang one with the black poppet that has no A,B,C postion marks on and it then made it worst pouring too much fuel into the motor. So I took it off and put the standard one on after cleaning it. I didn't mix up the carb body with the mustang one. The diaphragm seems working well... I put in new primer, floater and valve in the carby too. I can't think of anything else to replace.

Why it is still pouring too much fuel through. I removed the air filter. It runs well at start up for 5 secs & then runs rough low idle at full throttle, when I turn off the fuel tap it runs smooth then revs high and stops which is normal. If I control the fuel flow with the fuel tap ,it runs smooth.

What did I miss. I even have the Gregory's manual book with me.
Hope you can help as will appreciate it really.

I am a hearing impaired car mechanic and auto electrican and I do very well with team work. Am surprised with my self that I & workmates know nothing about victa plastic carbs. Here is a pic of the mower very similar to mine. Thanks
