Title: Knocked out the pistonsHours: 4 Cost: $0.00

Title: More Engine WorkHours: 2 Cost: $0.00
Work Descrption: 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.

Title: Put engine back togetherHours: 3 Cost: $0.00
Work Descrption: 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.

Title: Got it runningHours: 2 Cost: $0.00
Work Descrption: 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.
