I now use the thermal pellet If you did it the way I showed in the book, you will not have the problem. I showed a tubular spacer that allowed the thermal pellet piston to remain in place. The piston would put the bypass valve in the correct spot when the oil warmed up even if the spacer was a bit short. I also think I sized the spacer for use with the Racing Beat pulley to begin with. I think the same is true of the Atkins part. When using the method developed by Bruce (removing the piston and using a solid spacer) spacer length becomes critical. In Jerry Bass' engine, it resulted in the bypass valve leaving about a 3/32 x 3/16" hole exposed in the eshaft bypass opening. That's a lot of oil at 30 - 70 psi!
