Thanks for the schematic! If by intact, you mean still in one piece then yes, but internally it *might* be a different story (I hope not!). From what I am experiencing, it's as if #61 isn't even there anymore or #'s 3 and/or 4 aren't engaging #61. When I was turning the screw to max LEAN there was no problem at all, even turning clockwise to rich was ok. As soon as I got to max RICH, it was like the screw just went awol, weird. Worst case scenario, how does one take the lambda tower off?

Question: When the round throttle plate is pushed down, does gas enter the a non-running engine? Well, the remaining gas in the fuel distributor since the pumps aren't on, I suppose...
