Morris at "Morrisminimotors" had coverted a 7-77 to run on gas,using the carb from the Saito FG84,so I bought the carb adaptor from Morris and purchased a FG 84 Carb............... ( expensive !!! )..........
Ran the 7-77 today on gas,very pleased with the results,very even idle,fast and responsive throttle transition.........ran non-stop for 20 minutes,with varying throttle settings,cylinders appeared to be within approx 6 degrees of each other........I was using a mix of 16:1,bit on the oily side,but ran well ( this is the mix I am using on my FG 84 ).

I was running a Biela 22" x 10 x 3BL,...easily ran to 5700RPM,with more to go,but I think the main jet will need to be set a little richer for max throttle...Pretty sure that running on gas does produce more "torque" !!!

My 7-77 is around 2 years old and has approx 5hrs running time on it,during the carb conversion,decided to have a look in the back.........Having followed "Maxam's" after-run procedure ( but without the air pump ),I was pleased to see all was good in there !!!!

See the photos below for my conversion.
