Mike, after looking at the photo again maybe its 06606? I could of looked at upside down.

Yes that is a stainless steal wielding wire for a tig wielder and it releases to make it work. Well that's the way I got it to work. Don't know it its right but hey it looks right.

Ok the frames I have is #1 is 01277 is in good shape I may restore it someday #2 is just like #1 but where the number should be there's no plate there and never was. #3 is 90990 a good frame has attachments for the foot control and that is how I'm thinking of going with it. #4 the number is covered by the powdercoated but looks like #3 frame style but has no pedal attachment and break switch just behind engine. Here's a photo hope it helps.

Mike, yes I do like the old lamps I have a few. Well more than a few more like 37+

   Hi I'm new here but I've been around simplex bikes my whole life. I built a 58 model or at least I call it a 58 custom.  My engine was one that was giving to my father some 20+ years ago. When I got it with a bolt or two to hold it down and a shot of fuel after carb was brush out it ran fine on the ground. But after 18 months of mail ordering and driving many miles to get parts, its finished . It even ran several test starts once assembled . Then when I'm going to show it off to my brother and ride with him on his, its starts flooding the engine block with fuel. I've cleaned the carb several times reset the points polished the coil facing  but nothing helps . It won't run very well and the engine will almost fill up with gas. I even reset the carb adjustments to what the the manual said several times but no luck. Anybody have a clue what could be wrong. And as soon as I can get the picture thing figured out I will post a photo soon.
