Thanks for the heads up George, but I think we may have caught that issue earlier..
I have the prototype or first engine built and in that first season I tore it down and measured and checked everything between each race...
About mid season I did notice some slop developing in the wrist pin bushings and had them redone to tighten them up....
I had it apart again last year and at the beginning of this season and did not notice any new play issues.. so we may have corrected the initial problem...
Again this was the prototype, out for experimentation, and Don was aware of the wrist pin issue... I don't know if he changed anything in later models or if you have run across some of the earlier models.
I do plan on racing it this weekend in IL and I'm heading out of town tomorrow after work so I guess I'll run 'er as best I can, hope it continues to stay together and check er' again next week..
