Yesterday I received a set of Gen 3 carburetors for rebuild, purchased on eBay. The single issue I found in the listing photos is this bent "choke" rod seen in this photo (red arrow). I have encountered this before and my fix is to straighten it using a 2-pound brass mallet on a flat surface; an old-school anvil would be ideal but my smooth concrete floor will work just fine. I gently tap my way around the circumference and length of the mild steel rod till straight. Remount and check the choke operation — took me about five minutes.
But the interesting thing about this carb set are the intact factory markings all over the exterior shown by the smaller arrows. You'll see remnants of these markings on most carb sets, but I noticed that these are all still in alignment, indicating original factory assembly. The clarity of the marks are also evidence that these carbs have never been cleaned. So, I believe these are untouched, factory-assembled carburetors from 30+ years ago, something I've never personally encountered.
The exterior looks relatively clean, so I was anxious to see what lies inside. Not good; heavily varnished fuel coats the bowl interiors — those jets are thoroughly clogged. The good news is that the throttle, choke and diaphragm slides are all free. These carbs have waited long enough for a thorough cleaning and rebuild, and I'm happy to oblige.
