Mississippi Bullfrog Posted June 22, 2017 Share Posted June 22, 2017 Sounds like it's running rich to me. Popping is unburned fuel igniting in the exhaust, black smoke is classic sign of rich mix, poor idle is also a sign of rich mix.It will pull ok on full throttle once the rpm rises as the engine will sucking in enough air for the rich mix.

Westbeef Posted June 22, 2017 Share Posted June 22, 2017 Mine did this when running rich, wasn't even a nice pop on the overrun either. Just sounded like an old shitty car Mine was caused by me doing something dumb with the battery, so I probably can't help you. - Unless you've messed with the battery recently, then just check where the wires are Quote Link to comment Share on other sites More sharing options...
TimR Posted June 22, 2017 Share Posted June 22, 2017 Check the air filter is clean Check the choke is operating properlyCheck the idle speed compared to the owners manual and adjust accordingly . Quote Link to comment Share on other sites More sharing options...
