OK! No numbers.
The piston, I was told, is 235+.030
I measured the piston right below the bottom rings and parallel to the piston pin and the dimension is 3.566.
The popup is .266
Is Jahns still in business?
If so does anyone know an E-Mail?, A phone number? or any other means of contact?
Where is the right place to measure a piston to get the diameter?
Doesn"t a stock 235 = 3.5625? = 3-9/16"
