    I've done some searches here and read through the 2nd Gen carb rebuild thread but can't find information on the Starter Jet (Page 4-8 in the Service Manual). This jet, like the rest of them, was severely plugged. I got it unplugged down to the weep hole at the base. The question I have is: Does this jet feed into the carb body, or for some reason does it just end at the weep hole? If it does go into the body, where is the outlet port? I need to be able to push carb cleaner/air back down that tube to clear it. With the weep hole being opened, everything takes the path of least resistance.

    Thanks in advance,

    Couldn't figure out how to delete this thread. I finally found a thread where someone was having the exact same issues. Here is my response.

    Hope this helps. I found out where the jet goes. It took a while with a single strand of wire, an air compressor, and a lot of thought. Below are two pictures, the one showing the Starter Jet is pointing to the weep hole at the bottom of the jet housing. Plug this with your finger to push air/carb cleaner through to the the outlet (the other pictures). I blew air both ways and finally figured out the reason I wasn't seeing a lot of results is that the choke rod was out. I replaced it, pressed to seat, then put my air nozzle against the right hand hole (see picture) and finally felt a good flow of air out of the Starter Jet and the weep hole. Hope this helps.

    Dam, nice pictures! Nice little pointer hands too! Helped me! I am having trouble getting the actual carb. off. Can't see why, though? They had been off no more than 25 years ago?

    The pics were done using PhotoBucket editor. I was surprised at how well it worked.

    Using a steel wire (diameter .010") to probe that hole, you'll almost always find the first blockage at about 15mm depth........just exactly where the normal fuel level sits, drys up multiple times and leaves a small deposit every time. Starter jet hole leads to a hole inside the choke plunger area, clearly visible after removing the brass plunger.

    If passage is clear the wire will go in to a depth of about 33mm.
