Have you primed the engine with gas yet?
The best thing to do is engage the torque start on the flywheel as you would to start it, Then cover the exhaust with your thumb. Watch the fuel line, the fuel should start to travel up and reach the engine once the fuel has reached engine keep holding the exhaust going for about 2-3 seconds you may have to go for a little longer as I'd imagine it'd be pretty dry. Don't leave it for too long or you'll flood it tho.
