I had this excellent experience today. I took the carbs to a guy in Mentor that replied to my Craigslist posting for some help. When he’s done with them, and with his approval, I will do a nice posting about him, his shop, and of course his meticulously restored CL350 that’s also his daily rider.
Anyway, this guy is living the dream. He just finished grad school and has a really good day job but he also has a little garage in Mentor where he mostly keeps his excellent collection of motor toys and does little side jobs in order to pay for the place.
So anyway he starts taking the carbs apart on the spot and immediately shows me where I went wrong, explains what he’s doing, and mostly got them fixed…I think. I ran out of time so I’ll pick them up later in the week.
The really exceptional thing was that rather than just tell me to go buy a bunch of parts (that we both know are extremely hard to find for this bike), he actually put the effort in to work with what I have.
Here’s what he found (and is almost done fixing):
- Left carb (the one where gas was not making it past the float) – the jets were both still extremely clogged as well as a bunch of other parts that I didn’t even see because they were so covered with debris and gunk. As far as I know, this one is good to go.
- Right carb (the one that was getting fuel into the engine but spewing just as much fuel out the overflow tube) – same story as with the left carb, but he also found that one of the floats has a hole in it.
Now it makes perfect sense. The float valve is working (as I thought it was) but the float is filling with gas and is too heavy to go up far enough to stop the flow of fuel. Therefore, fuel keeps coming in and right back out the overflow hose. He got all of the really rotten old gas out of the float and is working on plugging it with a really delicate soldering procedure.
Also, since both idle jets were completely clogged, it makes sense now why it won’t idle..duh!
I am not only totally psyched up about the good change that this bike will finally be running by the weekend, but I also learned so much about carburetors today. The mystery boxes now make sense to me. Well, the learning is very much one of the most exciting reasons to get into a bike restore.
