 I have soaked the pistons with penetrating oil for months and was able to knock them out... Now looking for some rings... |  Pulled this out of a local salvage yard, I don't know what I was thinking... When I got it one spark plug was out.... Thankfully pistons were above the ports. |  Missing front headlight, front turn signals and a few other things, but most of it is there. All cables work. |  View of Kickstart and Shifter all in one |  Engine back together |  Under 700 miles, what a shame they left it outside uncovered...... |  Machined a new wrist pin bushing out of a tractor wrist pin |  Yes, heads on. |  Its running! Jumped electrical with 6volt tractor battery. |  Left Side |  Right Side after cleaning it a little. |
Work completed, time invested, expenses, and lessons learned.
Thankfully the pistons were up above the ports. Used penetrating oil for months and then knocked out the pistons... Was able to get some of the rings loose, then I busted one, so I decided to stop the project....
No description recorded.
Cleaned up pistons, removed rings. Going to get it running. Project back on.
Started putting needle bearings in top of connecting rod. Wire brushed a lot of the rusty chrome then spray painted it with chrome paint. Looks pretty good. Still need to machine a new connecting rod bearing retainer ring. Soaked bottom end with oil.
Took a long time to put the engine back together... Most difficult 2 stroke I have ever worked on... Needle bearings on wrist pin are free, had to make steel pin to hold in place, then pushed wrist pin through.. Also 3 rings per piston.... Got it together... Had to machine a new wrist pin bushing out of a tractor wrist pin. Used tool post grinder on lathe to do the job, then surface grinder for final width finishing.
Used a 6 volt battery to test electrical, most of it worked, ignition switch worked the lights but not the ignition system... Hot wired coils and it started! Runs ok considering con-rod is not great on right cylinder. Smoked, oil left over from soaking. A good day.
