First lets define top as the 'top' as you hold the engine upright, it is mounted inverted, so it is reverse when upside down.
Air pressure Inlet on top of carb: Goes to pressure line in fuel tank similar to the line that goes to the muffler in glow?
Pressure Inlet bottom of carb next to choke lever: hooks up to the clear tube that goes to the crank case?
inlet on side of throttle arm: fuel intake.
Also, onto the muffler, I have the bisson muffler from Tom at wild hare. It looks I need to plug the pressure tap in the muffler correct? And there is also this bar with one screw screwed into the muffler, what is that for?
Thanks
One of the carb inlets goes to the pressure line from the crankcase, I don't remember which one but it's the one that's closest to that line. The line only needs to be about 2 inches long.
The other carb inlet goes nowhere. Do not connect it to the tank vent line. The tank vents to open air.
You do not need to plug the muffler smoke fitting. That bar is to be bent and attached to a convenient mounting screw to support the muffler against vibration.
