I have an Enya 25 BB TV that i just finished cleaning and was not paying very close attention to what I was doing when I tok the liner and piston out.

In reinstalling the liner into the head, I see that there are 2 openings - 1 of which should line up with the exhaust port to the muffler. Of these 2 opening, one is slightly higher than the other.

My questions is, how do I know which opening go toward the muffler?

Thanks,
