Hello need some help my brother done a engine swap from his smokey engine to another 413 engine we no it worked from one of our old Sj we are having probs getting it started all trimmed up checked and checked and checked it's got fuel thought it may have been carb so whipped one of another sj that runs spot on but still no joy any one have any ideas would be grateful cheers

Its either fuel or spark.

Have you checked if its sparking and how strong it is?

Does the engine splutter or back fire?

I think he's bought a Vitara lump for it now....
