I am having problems getting the engine to prime by hand. When I flip the prop over the engine sucks the fuel just alittle bit but it never makes it more than 2 inchs up the line from the tank. I think on the up stroke of the engine is when the suction occurs but after that the fuel just goes back to the tank. I have it set at full throttle and I have my thumb over the carb. It will prime with the electric starteronly when i have my my finger over the carb.
The manual says the engine will feel like it doesnt have compression due to the dykes ring. It says this only works when its running.

I had the tank slightly over the engine and about level with it and it still didnt draw.
Is there somthing wrong with the engine?

The engine runs really well though, it idles real good and transotions good, considering I have only run about 10 ounces of fuel through it.

could you give me some tips on breaking it in? I have been just varying the throttle with it fairly rich. The manual didnt tell me really how to run it in.
Thanks,
Grant
