I have a tecumseh power sport H35 engine on my manco thunderbird minibike that i was trying to drain the carb float bowl to get all the left over old gas out. I assemble it back and tighten the float bowl bolt back on to the carb, I filled up it up with new gas and i notice that it was leaking gas from the bottom of the float bowl. I took it apart again, examine it and I notice that it seem like when i took it out the float bowl the first time i might have lost some part. A ring or gasket is missing from inside the bottom of the bowl cause you can clearly see a impression of where it was place before. If anyone have the same engine and can take it apart and show me what part i might have lost so i can get a replacement for it or find a illustration parts list for the float bowl that would be helpful. Thanks.
