well I put in the vent tube into the fuse ,cleaned and gaped the plug, and changed the prop to a wood 18x6
had a MA 18x6 that was beat up. It's better but not what I think it should be. Next thing I'll change is the fuel,
I'm using what I stole out of my kids four wheeler and not 100% sure of the mix. What are you guys using for
props? and what rpm are you getting? Once this is runnig right the next project is SMOKE !!!
