Just recieved engine from China, quicker shipping than from in the states. I am planning on putting it on the M12 Python, with a 23x8 prop.
Questions, the prop washer is so tight I can't get it on the shaft, same with the prop. Is the shaft larger than 10mm?
Do I need to use 22x8 for break in like the DA?
What fuel grade and mix are you using? Do you have any suggestions???
Thanks
