So I’m new here and there seems to be a lot of vintage Honda 100cc fans out there with a lot of knowledge so I was hoping you all could help. To make a long story short, yesterday I bought a cl100 for very cheap from a friends who didn’t know how to work on it. It had no spark so I just cleaned the points and the coil grounds, and I got the spark back. The tank is pretty nasty so I just hooked up a bottle with some gas and got it fired up. The bike seems to have pretty good compression and ran well at first. It was a little smokey but that was to be expected as I had put some oil in the cylinder and I don’t think it’s ram in at least ten years. It idled really well and seemed to rev out fine. Later I came back and started it again and now it wouldn’t rev out very well. Then next time it wouldn’t idle. Now it’s difficult to even get to run off of choke and it won’t idle at all. I pulled the carb apart (again) and cleaned the jets and all the passages and that didn’t seem to help at all. I’m totally stumped here. I’ve had some experience with almost identical carbs to this one before (1984 TRX200) and never had problems like this. I know the valve lash needs to be adjusted a little but it’s nothing too out of spec. There is a hole in the exhaust pipe and I know these engines run like crap with out a proper muffler. But I covered that up temporarily and anyways the first run, and best run with it was with the hole open. The floats sound like they have something in them and I know that fluid in the floats would make it run poorly, but it’s always had that in them so I don’t think it’s that. I’ve never heard of something like this happening. Maybe a carb rebuild? Just new floats? Whole new carb? Not even a carb issue? Any suggestions are appreciated.
