I am trying to diagnose a problem on a rv3 where a Rotec tbi was installed recently.
The engine stumbles and hesitates when it is cold around 1600 rpm; crossing 1600 rpm pretty mugh stalls the engine.
Once the engine heats up and oil temp is up after few minutes; the engine starts running better and the hesitation reduces and we are able to cross 1600 rpm and we are able to make full power.
The issue does not seem to happen in the air.
The rotec tbi was verified working by the rotec guys. This engine sat for few years and being flown much more regularly recently. It used to have PS5 carb before.
Any pointers on what to adjust or look for would be great.
