D2 pony compression

[Todd]

I picked up an old D2 last summer. It's about a 1950 model. The seller was able to get the pony going, but it was "finicky". There was rust in the gas tank, and the carb controls had to be "just right" to get it started and keep running. When I got it home, I got the gas tank cleaned and lined, and rebuilt the carb (new float, needle and seat, gaskets, etc.). The weather then turned sour. With the weather warming, I'd like to get back at it. The pony compression is between 60 and 65 pounds (both sides). Is that sufficient, or should I be thinking about trying to "refresh" it (and is that very difficult?). I understand parts can be hard to come by.

Also, the track adjustment nuts are pretty rusty - how difficult might it be to free them up?

I don't know about the compression, but on the track adjusters, I soaked mine with penetrating oil, resoaking them several times over the last 6 months, then loosened everything up, and used an air chisel to slightly spread the slits in the adjuster nuts. then hit on the edge of the nut with the air chisel til they turned a little, went to a big crescent wrench to finish adjusting. About 15 minutes per side. Mine is a 1944 d25j

I have several and all are in the 55-75 range. All start and run fine ,so I do not believe it should cause you any trouble. I have never seen the new or newly rebuilt figures.

There's nothing to worry about but if you did put new rings you'd have to pull the pony completely off so you can pull the top part of the pony which is were the carb and mag and manifolds go then pull the valve springs and lifters then pull the cam then you can get at the connecting rods so in other words complete tear down!
