Hi did you get sorted in the end on the X12🤝
Turned that inercia switch off and on as well, No differences…, (as to the starting matter) unfortunately not yet, It cranks over and has spark, However the fuel pumps arent priming at all., They’re both working when directly powered but not when installed?
