Currently experiencing an odd issue where, under full throttle, up until I get into 4th gear, everything is fine. A couple of seconds into 4th and it pops with a loss of power. I've only had the balls to keep the throttle open once and it continues to miss badly.
I've changed the fuel pump - about to change the fuel filter. It's had new spark plugs/dizzy cap & rotator arm/HT leads so will check the plug gap tomorrow.
Anything I'm missing? Has anyone else experienced anything similar?
Cheers.
