OK, I picked up this not running 1966 Lightwin 'Folder' at a bargain, after some cleaning up, it looked in very good condition. The first thing I checked was the spark, it had none. So I ran a file through the points and viola, good snappy blue spark! So I flushed and dumped some gas through the tank, replaced the fuel line & spark plugs, put it in water and fired it up. It would not stay running with throttle in 'start position unless I kept pulling the choke on and off. Even after warm up. So I got a kit and went through the carb. Now it will start and run on low idle, but try to move throttle up and it dies about 1/2 throttle...??? I kept pulling the fuel line off the carb to see that gas was still running out. I noticed that there is no Hi-speed needle valve like my older engines...??? I believe I adjusted the float to spec...??? I did replace the needle & seat. I did not replace the coils even though they look original because I didn't see any cracks and it has good spark in both cylinders cold and warmed up...??? There of course are a lot of extra parts in the kit, did I miss anything...??? Any help would be greatly appreciated. '66  3hp Evinrude-3.jpg

So it actually dies out completely or does it just sound like it's not achieving full rpm's? And gas is flowing freely through the line? Tank vent is open? Kit will have extra parts as they are designed to service more than one engine.

thanks for the reply...it would die completely...I found some info on a similar post and I went back and removed the fixed hi-speed jet and cleaned it out with a tip cleaner...works just fine now, thanks again

What is a tip cleaner and where'd you find it?
