I took my carb apart cause it has 3-year old gas in it, and the engine would not start. I found the float stuck, and decided to clean-out all passages. The idle ciruit jet (38 stamped on it) with a diffuser tube on the other end was plugged when trying to blow cleaner through it. My question is: Should this jet be plugged? I've never seen one like it befiore, so I drilled/reamed it out to .038 inches. The drill removed something white, but no brass so I thought things were cool. Upon reinstalling to the bike and filling with fresh gas, bike fired right up. Now it runs way to rich at all engine speeds, and has an unsteady idle. It never did that before.
Any thoughts from other carb magicians?
Thx

Brian S, I think you are on the right track, The diffuser should be clear so you need to work on it some more. Put away the drill bits and use a good cleaner you can soak it in. And use air pressure if iys available. For that matter you probably need to strip down the whole carb and soak it. Make sure the low speed/idle circut is clear. Better look at the float,make sure is not leaking. Check the float setting very carefully when you reassemble and make sure its not hanging up in the bowl or on the bowl gasket. And make sure the float valve is working. Good Luck, Steve Greer
