Anyone on here ever fit one of the Hyperpak units from NZ on a 4a with carbs? It says in the instructions to set "Static Timing" to 15degrees? I've tried puttin the crank to 15 and dizzy at No1 and it will start put pops and farts. I've tried setting the bottom pulley to 0 and putting the dizzy in a tooth or 2 advanced and will start and idle, revs a bit better but still sounds like timings off. Any ideas?
