Not sure how long it’s been happening for… but we noticed today @ full throttle, when downstreaming the motor was stressed & emitted exhaust smoke. Takes about (10-20) seconds in downstream mode before the exhaust smokes.
We went down on the throttle a bit & it cleared up. We were working on a (3) story complex when the issue was noticed.
The injector (2.1), on the whip line, with remote ball valve. Igx800, 8.5 pump, gear reduction, direct drive.
Anyone experience this?
