Marvel Schebler Float Bowl

The economizer jet is not used in all TSX Marvel Scheblers. Some installations require a leaner condition so the economizer jet is added. You can spot the 2 jets by taking the top and float bowl apart. On the top of the float bowl there will be 1 jet, which is the idle jet, or 2 jets, the 2nd jet being the economizer.

The main jet is at the bottom of the fuel bowl. In the illustration there is an adjusting needle which not all Marvel Scheblers have. This adjustment allows you to adjust to different applications.

Look for 2 holes at the bottom of the float bowl. Be sure these are clear. You can blow air through the holes to check. They may be covered with so much gunk that you can’t see the holes.
