Went to unload the car today and the drivers side slick was flat. I knew I was on borrowed time with these but they still showed decent tread. I have been eyeballing radials so maybe it is time to try a thinner slightly taller Hoosier or Goodyear radial.
This will probably keep us from running Brainerd again in two weeks but we still should be able to make Commerce on 7/24.
Next time out we will go back to experimenting with fuel, try new tires and probably change the MSD distributor spring to a stronger one to prevent the idle creeping. also going to replace that 6400 rpm chip in rev limiter.

Lots to do between now and then.
