ok I think iam ready to try my gas to glow ryobi today if it stops raining. This is what I have done so far. I have taken a spark plug adapter (adapter used to stop oil fouling on plugs) drilled and tapped for the glow plug then I took an old fly wheel and using A hole saw cut the center out and used it for a spacer ring behind the prop adapter. for fuel I am going to mix up only a little to see if it works ( 1pint of 10% nitro and 10% oil to 2 pints of gas )I know the form said 1qt glow fuel to 2qt gas but dont want to use all my glow fuel up. I am goine to use the stock carb ( my new carb is not here yet its a wt 499 ) I am using A os type f plug. Iam going to use a starter and mabey flip it over if I can get the carb adjusted out. so what do you all think michael
