Hey guys, have been over in the I/O department as I'm working on my old ski boat & this outboard has been running great. My question is do the carbs have an adjustable idle mixture or is it controlled by fixed jets? It's a 1990 60hp Johnson w/ vro removed. Serial #TJ60TLESM. It appears to be running rich at idle. The plugs are soaking wet every time I've removed them. It will load up after idling for 10-15 minutes & it seems to be using an awful lot of fuel in general. It fires up easily enough when it's cold & when it's warm I can't turn loose of the key fast enough, it's running as soon as the starter engages. Any thoughts? Compression & spark are good & new non vro fuel pump & all new fuel lines. It runs great just using a lot of fuel & seems especially rich at idle. Thanks. Jim.
