I think I have this SA200 figured out finally. I went to a big tractor wrecking yard and got a sediment bowl off a MF 760 diesel combine of all things. It has a deeper bowl and also a screen about 2 inches long that goes into the tank. I also bought a new screen and gasket for the bowl. I put a new fuel line on and went as straight down as possible to the carb. When I first turned the gas on, I thought I'd have to crank it a while to get any air out but it started in about 3 revolutions of the engine. I was amazed! Later on it took longer to start but was still about twice as fast as before. I did notice fuel dripping from the carb when turning it over. The carb has a special feature to drain excess gas so it doesn't get pulled into the cylinders. After a few trial and error attempts, I think I have it figured out. When the engine is shut off, there is still some gas sucked into the carb but not enough to get to the cylinders, so it stays in the carb throat. If there's too much, some will drain out the bottom vent but not all of it. When I go to start it the next day, it takes longer to crank because the little bit of fuel in the throat is slightly flooding the engine with full choke. I found it starts better if I turn the engine over without the choke for a few seconds before pulling the choke. I think this allows the fuel in the throat to be sucked up without flooding the engine. I will test this theory again and see if I get the same result. The mechanic that installed the carb said as long as there isn't a pool of gas sitting under the carb, it is normal for the vent to be wet from gas. It is dry when the engine is running. Does my theory make sense? Dave

Today's Featured Article - Fire in the Field A hay fire is no laughing matter-well, maybe one was! And a good life-lesson, too. Following World War II many farm boys returned home both older and wiser. One such man was my employer the summer I was sixteen. He was a farmer by birth and a farmer by choice, and like many returning soldiers, he was our silent hero: without medals or decorations, but with a certain ability to survive. It was on his farm that I learned to use the combination hand clutch and brake on a John D
