Fair enough. Ted nailed the issue anyhow, as usual!!

Frank, I checked the float height but didn't bother with pressure as pump and carb will both be replaced in a couple weeks. Just figured this thread might help others with similar problems. Thanks, Mike

Mike,

      Check your float height, and maybe fuel pressure also. Either issue will contribute to the high throttle setting miss.

Reinstalled the carb today, big improvement! Engine much smoother and no more smell of gas. Still cuts out at higher throttle settings but better. Seems more like an ignition problem. I can live with it till I pull the engine in a couple weeks to perform the upgrades. thanks for the help guys Mike

Those type of non-threaded seats are now not included in the new carb kits. It says re-use your old ones with the new needle valve. That is fine if the seat is in good condition.



I have changed up many of those spring loaded type of seats to the threaded type by threading the float bowl to accept the threaded seat. The threaded seat is 24 TPI however is much larger than the 3/8" diameter fine thread bolt.



I found the tap for installing 24 TPI (3/8 SAE bolt) heli-coil coils is same OD as the seat threads are. I just start the tap nice and straight so have a clean thread than replace the old spring loaded seat with the newer threaded seat.



On a disclaimer: Before using a heli-coil tap I would try it in a piece of metal to do a test thread as maybe some heli-coil taps are different sizes than the one I have. I would not want someone to ruin their float bowl by a mistake.

Daniel, seat drops into the carb body, a spring rests on top of it then you screw a threaded cover on that presses on the spring holding the seat in place. I installed a o ring today and the seat no longer leaks. Just need to install the carb and see how it works. Mike

Be sure to use some white grease or Vasoline on the rubber O ring during the installation process.

Ted, it has a spring loaded seat but a fiber gasket. I was already thinking of installing an o ring, now I know that is what it was supposed to have. Thanks for the help. I will post the results of the surging problem.
