My 78 B, acquired about 6 months ago, has a Zenith Stromberg carb which worked fine until the weather here in good old New Mexico started to change. Now, it is slow to start and hard to turn off: takes a lot of cranking in the AM, and diesels a bunch at the end of the ride. I have a Weber on my 74 Midget, so the Z-S looks like a foreign object to me. Any suggestions on what to do with this gadget, and is there a good Z-S Carb tuning guide I should get my mits on? /ubbthreads/images/graemlins/driving.gif
