.15 cox engine différence Need of information
For the engine of fred I have a sportsman piston I wondered that the crankchaft pin is of the same dimension to the médalion model I believe that this model comes with a different piston, if my memory is good Is that the model with a pin is different?

David,
Do you have a dial caliper or micrometer? I could pop one of my Medallion .15s apart and measure the crankpin.

Re: .15 cox engine différence Need of information
Yes i have a numérique caliper I think it will be the same as the sportsman But it is almost sure that the cylinder will fit unless it different threads Me the only .15 cox that I have is som sportsman no tee dee or olympique It's a lack on my part I used to know a bit of everything on cox engine And it's the only model that I don't own yet as the .15 médalion or tee dee sale à bit expensive 10 years ago I saw several for sale Prices around $ 80,120 for new engines I always prefer the smallest that's why I don't have .15 I preferred to buy .9 I will one day own them all the difrent size and models
