Garrett County, MD | Does it start well? I have seen injection pump timing cause things like that but it would be obviously not running well. Easy to mistake that on first firing up, but after 1 hr on dyno at load it should run well. If it still sounds like it did at first startup it could be pump timing. That low hp it should be something pretty obvious.
I guess this is unlikely but is the dyno working properly? | |
