Tripower float adjustment help
Need to replace O-rings due to a leak and am not sure how to remove the screw and nut. Do I need to remove the end of the carb where the float is? Can someone tell me the order of how I need to replace the 2 O-rings please?
Thank you all

The only O-Ring is the O-Ring sealing the needle/seat assembly to the bowl. A faulty O-ring on the seat will cause internal leakage and flooding conditions - it will not cause an exterior leak condition. There is only 1 O-ring - not 2. What, exactly, are you trying to replace..?

Jim -
Are you talking about replacing the gaskets on the float adjustment hardware on the exterior of the float bowl...? There are no O-rings there - they are just flat gaskets. Hold the nut steady with a 5/8" wrench and use a wide-blade screwdriver to remove the slotted head lock screw. Once the slotted head screw is removed, you can lift the adjusting nut off the needle/seat assembly. Use a razor blade to remove the old gaskets, and install new gaskets after putting some wheel bearing grease between your fingers and rubbing the gaskets with the grease between your fingers. This grease will prevent the gaskets from tearing when you later adjust the float level. Place the new, greased gaskets onto the parts, drop the adjuster nut in place, and screw the slotted head lock screw back in place. Give it a mild "snug." Once done, start the engine and check/verify/adjust your float levels.

I was worried that the float would drop off the screw and then I'd have to open up the front of the carb. Glad it's not the case. Easy enough. Do you think the float level will change if I keep the position of the nut the same?

If the rotational position of the nut is not changed, the needle/seat installed position remains unchanged. The needle/seat assembly must be rotated on its threads in order to change height. If the float was right before, it will be right after the gasket change. If it was wrong before, it will be equally wrong after... Make sure you apply that lube to the gaskets - it's essential for gasket longevity and sealing.
