HMM...
Couple of things, the indicated mileage is estimated with exception of the 198 miles last time and the mileages on this run and are since the engine build. I had misplaced the records but have since found them.
I strongly suspect the fuel pump is leaking internally as well as externally and that there is more than a trace of fuel in this sample, going to fix that.
The advice to listen for a ticking sound it a little amusing since it is a solid roller... It doesn’t make any abnormal noise and runs strong.
All 338 miles of this run was back and forth to the landfill with yard debris and several loads (like 2 tons worth) of egg rock...
