My 2001 Jackal now runs really well when warm. No hesitation pulls, strongly in all gears, and really flies. But from cold it feels particularly rough, not how I remember my old one (or indeed how my next door neighbour who also had a Jackal remembers).
Is there anything in particular they suffer from that may affect initial running after start up?
I have a similar cold bug on a 1996 Cali, same block different Euro compliance as yours. Starts up on one cyl unless ambient Temp is greater than 10C. Runs regularly after standing for a minute.
In my book that’s not quite broken, so seeing as it’s got no mods or improvements to the wiring, filtering or fuelling i’m leaving well alone until the inevitable catastrophe.
I looked over a Jackal with the hydraulics before settling on mine, lovely engine on it
