Default My 5HP Project, frame Donated from (Womens Schwinn)

i started this today, frame moded, and the motor mounted. If any one has any ideas i would love to hear them.

does any one know about relocating a gas tank on a briggs and stratton, will the gravity feed flood the engine if the tank is mounted above the carb?

This looks like an AWESOME project!

Disc brake is nice.

i can't imagine why a tank above the engine would cause problems.

A rack-mounted or one above the bar would be okay, I would presume.

What's your driveline gonna be like? No pedals?

If I were me, I'd do my darnedest to keep the pedals for two reasons:

If engine fails, I can pedal to my destination.

It helps to "ghost pedal" when "Johnny Law" is in the vicinity.

Hi kcbford1,
It looks like you have a diaphram carb on that engine, with the dip tube coming out the bottom. Meaning that, the tank bolted to the bottom of the carb. That tank and carb have to stay together.

You could however, change to a float bowl type carb and mount the tank above the level of the carb somewhere.
The float needle keeps the carb from being flooded. It's a good idea to have a separate shut-off valve on the tank, though.
