Re: Mark 28 issues

I agree that the grooves should be clean. When I do this, I concentrate on one ring at a time. I get them aligned with the locating pins as close as I can. I then insert the first ring. You may have to rotate the crankshaft slightly one way or the other so the rings can find their place on the locating pins. The STP really helps. After the first ring slides in, concentrate on the next while being careful to not over stress them and break them. These are much easier than the 11 cid. 9.8 hp. motors as you have a bit more room for your fingers. I often mark the rings with a marker so I know where they need to be to fit into the locating pin. After the first cylinder is in, rest your hands a moment or two and then move on to the other one. Like I posted, I find that putting the bottom cylinder in first makes it easier. You most likely will have the top cylinder rings all moved while working on the other piston, so it is much easier to see them plus you have more room to work. Also, as was mentioned, Oak is a better wood than popsicle sticks, even a brass or metal rod etc. that can slide on the STP. I used to use them on Hurricane blocks, but now I just use a hose clamp on them. Take your time.

My confidence is high!
