Started the 6-71 up today and it covered the wheel of my golf cart with soot. Flaky black stuff that you can blow away. I held a board over each exaust and it's only coming out of one exhaust, has to be #1,2, or 3.
Any idea what causes this??
Blowing soot is incomplete combustion, usually from a clogged air filter or driving in high altitudes. I would take the air cleaner off and retest, and it that isn't it I would pull the exhaust manifolds up and see which cyinder(s) it is. It could also be a bad injector (blown tip), but I would do a compression test before I bought any parts.
