How did you make the carburetor?

[nmsteam]

@SthealthRaider The carburetor is a simple fuel mixer with a needle valve similar to what is on many model airplane engines.

make a boat!

[nmsteam]

@KingSlimjeezy I live in a dry area. Not enough water to float a boat any where near me. Less than 4 inches of precipitation in 2011.

how is it timed

[nmsteam]

@15jwilli Timing is by a magnet in the flywheel actuating a Hall effect sensor to trigger the capacitor discharge ignition built into the base.

Excellent! That should get great gas milage in my '78 Ford Econoline E250 van.

0:30 and on its running as it should. but given there is no throttle, i can see why youd use a rich running condition as "idle". do you know where i can get plans for this engine?

@nmsteam I really want to build one of these. However, I lack the know how and the materials to do so. Perhaps you could sell duplicates of all of the components and create an instructional video?

[freakshow3850]

i want to buy it

@nmsteam cry me a river ;)
