Well done Ade,most of the videos I've seen on youtube when they move from continuous to

hit and miss need to adjust the carb, what did you do to not need any adjustment ?

If you do send in a photo for engine of the month you've got my vote.

Regards Trevor.

Hi Trevor,

The adjusting the mixture thing is because the carb venturi size is too large, there is not enough suction in hit and miss mode therefore they have to richen the mixture.  To fix this and the 'off governor' speed i remade the carb with and adjustable throttle slide so i could find the sweet spot, was easier than making lots of carbs with different size throats  :D

Thanks for your support
Ade

What a fantastic job you have done on this engine.
I started watching a while back but must have missed the finals.
the switch in running speed is brilliant.
