Les asks->I assume that this flat spot and slight black smoke as you speed it up>is a indication of incorrect float level. I have installed the new delrin >needle>with the recommended float weight change.Not sure if it's a float level issue because you didn't say which carburetor you're using, but if it's a Stromberg NA-S3 series, it could possibly be. There is a bit of fussiness about setting the float level but it's been perfect on mine since Corky set it up and since I changed the carb to one overhauled by Deanie Montgomery. Deanie puts them on a flow bench to set them up, but if you want to fool with it there is detailed information in some articles authored by Neal Wright athttp://www.bowersflybaby.com/tech/engines.htm (under "Technical Help- Neal Wright on the Stromberg Carburetor"). It has to do with fiddling with the combination of various thicknesses of float bowl gaskets that come with an overhaul kit.You can email Neal at COUGARNFW(at)aol.com if you want to discuss this specific problem to see if it's related to the float level.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Tue, 01 Feb 2005 12:42:22 -0900
