For what it's worth. I have found the best way to start the Taurus is to leave the ignition off, choke on, and almost full throttle. Flip the prop over until the engine sounds "wet." Then open the choke, reduce the throttle to idle, turn on the ignition and flip the prop. It usually only takes a couple of flips to get it running.
I'd recommend
against using this starting procedure. Simply because if you forget to close the throttle you're in a world of hurt. This is very dangerous IMO...
In any event opening the carb up to full throttle should make little to no difference. Think about this, the choke is closed. This is a diaphragm pump vacuum actuated carb. Opening the throttle butterfly does nothing... Unless the engine is running.
I have six Taurus Engines, they like nearly all the rest use a Walboro carb. The procedure for starting is generally the same across the board. I use the same method of starting these little gasser's as I do on my engines including the 100 and 150cc engine's.
Try this method:
Activate choke, switch on the ignition, flip the prop until the engine pop's sputter's and dies, [if you have the servo activated choke you can turn it off if your quick enough and the engine is running] Turn off the ignition, deactivate the choke, turn the ignition on and flip the prop until the engine fires. Generally if all things are right the engine will require about 3-6 attempts to sputter with choke on and about the same to fire the engine with the choke off.
