Default RE: Zama needle settings

Just reset the needles and fired up the engine with the Zama carb. After a little tweaking of the low needle (open) it has excellent transition and nice steady idle with no more flooding. High end is better than I expected at 7400 on this 20cc engine with a MA classic 16-10 prop. Tried a new timing curve written by Nyemi for my timer and now also get one finger flip starts when warmed up. No tendency for kickback at all. What a wonderful day it turned out to be!

I have alot of ignition boards and new advance boards made up if anyone is interested. All they require is an ignition coil which should be available from Adrian at CH Ignitions with your choice of shielded plug cap. Pm me if interested in a setup for your conversion engines.
