When you decarb, you find out how things are. I called the F.D. with a heads up the first time, and that was at the ski boat ramp. Big cloud. Wind blowin` a lee and 10 ft. vis.

I run Penzoil semi synthetic. Hardly any smoke on the de-carb this spring. I`m thinking of pulling the heads just to replace the old gaskets and check the cooling passages.

There is a reason why they invented synthetic oil. We went to the moon.

Heavy carbon can lead to pre-ignition and cooling is paramount as well.

Harbor Freight makes an inexpensive infrared gun. I run about 147 idle and cruise. Lil` more when she gets hungry.
