i've done everything i can think of.

Timing is 100% spot on, got spark, got fuel cos it stinks she just won't start. Checked all the earths and even used a jump lead to improvise an earth in random places across the engine.
The only thing i can't check is the compression, although the head has only been bolted down 48 hours so it should be alright. Changed the dizzy today thinking it might have been the condenser unit but still nowt. Confused and gettin quite annoyed with it to be honest.

Wanted to take the heap to pf night tonight, but i guess i'll be hovering over the engine bay till it gets dark again tonight looking for whatever is causing the problem !

Also.. is the Mfi cam different to a Carb cam ? i ask because the replacement cam i got is from an MFI head and wondered if that'd make any difference.

Engine is a 1.6 Carb cvh.
