Author Topic: piston stops and life lessons... (Read 728 times)

I've used nylon cord as a piston stop for years and always found it humorous reading about people getting the cord stuck. Seems like that would require carelessness or ineptitude I reasoned.

Sure enough I joined the ranks of the inept a couple days ago after locking a piston solid with a piece of the first nylon rope I grabbed, a piece of starter rope. Went right into the exhaust port. The muffler was removed to see the end of the rope but the piston was still above the port, stuck way past moving with the starter. I finally got it moved down with a soft punch striking on the clutch, rope came right out and now all's well.

A good dope slap from reality seems to be an excellent arrogance reducer at times. It's a plus when the arrogance reduction is cheap too, makes it much easier to laugh at ones self, haha...

Ah yes, a good serving of humble pie has done me lots of good over the years.

I always use a cut V-belt and never had an issue. Pretty hard to get that down a transfer port, but I guess anything is possible.

I haven't had a chance to use it yet, but I remember you mentioning Vbelt before Kevin. That sounds like a great idea to me.

Yeah Real1shepard, that v-belt idea is on my list to try next time. Sometimes the simplest things are the hardest to improve on, I think that one is a score.

Can you explain what you mean by this ? Trying to understand the reason.

I think they’re using this to put down in spark plug hole to lock engine to be able to remove clutch or flywheel.Someone correct me if I’m wrong.I know a screwdriver in the flywheel fins will break them.Don’t ask how I know

I have a dedicated rope for doing this. Its a bit thicker than the pull cord. I made a knot on the end to keep it from going through the cylinder ports. I try to remember to bring the piston close to TDC before putting the cord in.

Ahh, makes sense

Of course if you us a impact gun it's way less abusing in the parts than doing it with a big wrench trying to brake free the nut.
Maybe it even brakes free without jamming the piston
