ok i fess up. i busted off the bottom casting of carb that is threaded to accept the jet. When i put the new parts in i barely tightened it and it broke off . . . so i jbwelded it together. hasnt run right since.
yes, d'oh, the slides are right, and the needle seats are ok. this is more of a not run in almost any position. It's been fun, as ive learned all there is to know about how these things work.
interesting, though, i can get it running (one side) and the other (with the bad carb) gets going intermittently at high rpm. so the other day I put in the new needles that came with the rebuild kit , and bam, the thing won't run. at all. Also, of interest, it'll run great with the 120 jets (again, same symptoms as above) WITHOUT air filters, but with the 102 s i have to have the filters on.
blah blah balah. It'll work with a new used carb. I am, however, trying one last thing. As I really think it had something to do with the connection between the needle tube and where it meets the insert, i popped the insert down a little into the bore, and I am going to see how it goes with seating the needle tube up into the bore forcing the insert into a place that is comfortable. (in other woyds, when I insert the tube as far as it can go, it is not making contact with the insert. there is an "air tube" in the cast carb from the front of the carb that goes directly to the top of this just below the insert. If there isn't a seal there, all kinds of air will be sucked in. I think. ).> but its POURING RAIN ALL WEEKEND AGAIN so I won't find out for a while. Regardless, Tanks for the carbs.
