My 58cc Evolution engine seems to have developed a little free play in the crank. I can move the crank in and out with a slight click. Not more than a thousandth or two. My thought is a front bearing.

It has about 6 hours on it.

Out of warranty. Have had it on another plane and not flying it caused the warranty to expire.

Using evolution synthetic oil mixed 30:1 with Hi octane gas as recommended.

Is this something I can fix? If so, how?

Is it something I should worry about?

Thanks in advance for any help.

Bill
