Well tried the electric lift pump idea with no change in how it starts with cold engine.. so now really puzzled on what changed.
Received around 8” wet heavy snow Friday and ran fine while moving snow for over an hour. Did notice during this time that throttle would drift back to around 1700 RPM if set at any speed above 1700. Did not notice this when blowing snow earlier this winter. Will rev up to 2,600 at stay there as long as you hold the throttle. Suspect friction nut worked loose.
I did clean the injector pump before swapping feed pumps and saw no evidence of any fuel leaks.
