Aero Nut I have a ? My roybi runs on gas /glow w/out heat ,But is real rough I'm using Byrons 10% nitro with 10% oil mixed with 93 octane gas' I raised the tang on the regulator in the carb the mixture is 2 part gas and 1 part glow also using a Zama 13.5mm carb I got Scott Ellingson[Brillelli Engines]. My glow adaptor is from Horizon and I'm using a 4 stroke Plug.
Do you think I need to increase the glow fuel in my mix to keep the plug hotter? I'm at a loss here and could use some help.
Whenever I put the battery heat to the plug the engine smooths right out goog wot and good idle.Thanks for any help you can give.
