4KCSQ starting/running/power/etc problems

[Jukka Majanen]

Hi Patrick

Late firing and no work down 1-3k usually mean lean mixture.
I think You have air leak between flow sensor and engine.
Means unmeasured air in the engine > not enough fuel.
Can be intake line, or some aux hose in the manifold.

Of course Your pump and filter are ok?

luck
