Why is it that the kohler m18 in my 1992 magnum needs a lot of time to warm up?

Kohler m18
yes, that's a good question Curtis. I remember that we used to cover the grill area in old cars to help them warm up. Your air cooled kohler engine fan blows when the engine starts cold or not. it has to idle for a long time with the fan blowing and no load on the engine to even start to heat up. My Avenger is liquid cooled and has a thermostat in the cooling system that stays closed till the coolant warms up. Still it needs to idle a bit before I can back it out of a covered trailer on minus double digit celsius days. I have a shut off on my brake cooling fan to stop the fan from making the cab even colder. I wonder if throwing a coat over the intake air screen would help?Originally posted by curtisbyrne View Post

Good morning Curtis, your machine will take a long time warm up at idle speed which is around 650-700 rpm. Try a higher idle speed, around 1200-1300 rpm with the choke pulled out a little to richen her up.
How do you get it to stay on high idle you ask, well buddy that's a good question and there are a couple solutions. One is to push the twist grip throttle against the handle bar inside the grip, another is rig a cable with a sink chain to pull on your linkage while idling( also works like a cruise control. There are a few hazards so remember to always(!!!) start it in neutral.
There is an outfit that sells a throttle lock for twist grips but I do not know where to get them, my rig has this option and it works awesome. // RRComment

So maybe hook my brake blower fan to a toggle switch to keep cold air coming in when warming up?Comment
