"My 90 hp motor was bought new
"My 90 hp motor was bought new and worked great up until now.
It starts fine, but at low rpms, idles terribly. Once higher rpms are reached, it runs great but have to "feather" the throttle to get it past the low idle problems.
The filters, plugs,and fuel have all been replaced. A mechanic has cleaned and sync'd the carbs but it still isn't idling.
any suggestions?"
