I have the 1.80 and it is mounted sideways on my plane so if your engine is mounted differently this method might not work for you. Also, I use a chicken stick with this method.

Here's my method:

1) Close the carb and plug your muffler with your fingers.
2) Turn the engine over until fuel comes out of the breather line. You want fuel to come out of the breather line. (It might be flooding, but I don't get any sort of hydraulic lock with this method)
3) Take away your finger(s) from the muffler and open up your carb. You should hear a wet suction sound. That is when you know you have primed the engine correctly. Again, you might be flooding, but you shouldn't get any sort of lock.
4) Turn the prop so it is on its compression and attach your glow starter.
5) Flip the prop against compression with a chicken stick and your engine should start on the first flip. If not, just flip a couple of more times and it will start.

I use this method everytime I start my engine and it starts on the very first flip of the prop.

Just my 2 cents!
