Adamw Posted August 5, 2023 Report Share Posted August 5, 2023 Not much info given here, but if it is kicking back when cranking that would suggest the timing is wrong on at least 1 cylinder. It could be trigger offset or wiring or firing order etc. If you disable spark - either in the software or remove the coil fuse, does it then crank smoothly?
