I put a can of sea foam in a full tank. Discovering that is way to much for recommended amount. Would this cause running problems? My Sambar was running fine until this event. It has used just over half a tank just idle for a couple of days.
Shouldn't hurt it, but it may bust loose some crud that the filter might catch and cause it to clog up. You can pour undiluted seafoam into the carb and it will still run, just creates a smoke screen! I've sucked it thru a vaccum port to clean out engines on other vehicles before, won't hurt anything. Just refill that half tank with more gas if you are worried, that will dilute it down further.
