The engine "unstucker"
Posted: Mon Sep 26, 2011 6:06 pm
Today with much fanfare I unstuck my stuck Duc. Yes indeed instead of lawn art it has officially become a money pit. I've lost my excuse of "I'll start working on it when the engine frees up". So I filled that hole with every slippery thing I had on hand and could not get it to free up. Then I was reading about people using grease guns to force pistons free. Me being me,

(Sorry about the crappy cell phone picture)
I produced the engine unstucker device. Most people were talking about beating up old spark plugs to make them, but I recalled a thing called a spark plug anti-fouler. I got one and a 1/4" brass pipe fit it dead nuts. It threaded in tight enough to make a seal but I backed it out, sanded everything, greased it up with some flux, tightened it back in and used a propane torch and a little solder to make it extra nice. A quick drill and tap for a 1/4"x28 grease zerk and it was all put together. Not bad for $6.
I filled the cylinder up through the plug hole with my grease gun and then threaded the "unstucker" into the plug hole. A few short strokes later I felt the piston free up. I removed the unstucker and gave it a kick, folks I'm so happy it was outside as a pint of grease shot across the yard about 35 feet.
Ah where to start on this project.






Oops, that's not a bevel.....
