Hello all honda lover's
I recently acquired a honda b75 ser # b75-1003075 and it had some top end carb issues. The main jet needs an 0 ring and fuel shut off needs a new rubber stopper.
So I decided to remove the dirty gas carb (gasoline is a dirty fuel with all the carbon, and gas souring in 60 days due to ethanol, carb is very clean), and build a very simple propane carb for the motor. Just some copper tube and a good regulator.
So if have carb trouble with a 4 stroke honda this maybe an option for you
Have the idle now down from spec 1200 to 575 and purrs like a kitten, a top end is same at 5000 rpm
Use a $13.00 20 lb bottle of propane in 50 hours at trolling speed
And more worries about storing the fuel, and my brother can not steel the gas for his car
just a thought for anyone with an old 4 stroke that the parts are obsolete
