I guess I am need of advice again. I was removing one of my carburetors and out fell a little broken piece of a metal pin.....:huh. Now I'm thinkin' I had better rebuild the carbs. I'll add a picture, but it's about 1-1.5 mm dia x 1/4" length. I am mechanically inclined by trade, but I am wondering for a first time rebuild if I should risk doing it myself or ship them to someone like Bing. Did anyone try this for a first time and have a lot of issues or is this a straight forward process? Also, any reviews on Bing's updated float and bowl...Is it really a 4-7 mpg improvement + improved torque? Responses will be considered data on this one. Thanks a bunch!
