I have a quick kinda dumb I guess question to ask.I have a 1984 Johnson 90hp with the VRO disconnected mixing 50:1. I went to start the motor tonight on the muffs and it idled around 1000rpms to 1500rpms is this to high or is this a normal idle on the muffs.I didnt know if the motor kinda depended on back pressure from the water to kinda idle it down a little bit.<br /> Also the boat hasnt been started for probably 3 weeks to a month due to being in the shop for a foot related issue. It also smoked pretty good while it was running and left a nice rainbow on the concrete while it was running.<br /> Any answers or advice is greatly appriciated.
