I have an old Polaris Big Boss 6x6 that keeps dying on me. It started happening slowly over time, weeks, now every time. I have to keep revving it to prevent it from dying at idle. . . So, it seems the natural / obvious cause is the idle jet in the carb. However, wondering if I should also be looking at the ignition / spark system(capacitive discharge system, components) too? OR, something I have yet to consider. . . before I start tearing into things. Thanks up front folks!
