Mvvs 1.60
MVVS 1.6 gas ( new version with Vlach ignition and walbro carb with choke ) .
Got a chance to see a friend tach the engine ...
Apc prop 18*10 @ 7400 rpm with stock muffler.
After changing to the Bisson muffler pitts style the rpm shot up to 8050.
The engine is well run in and has a lot of fuel through it already.
