The little brass screw that connects the choke bracket to the nozzle was super tight - looks like I messed the screw head slightly. Might have to replace some dome and fuel bowl lid screws too. They're all brass screws I haven't seen before: for a flat screwdriver but what looks like slot for a phillips too. Are those available? British Classic Motors sells sets of SS bowl and top screws w/ socket head, don't know if they would fit the Hitachis but can ask them. Is SS OK or should they be brass? Seems like you could wreck the threads in the carbs with SS if you're not careful. Is there a carb screw size list anywhere?

The carbs are rebuilt I guess (shiny new brass stuff and no throttle shaft play) 72's installed by PO.

You can probably get the original screws from Z therapy, or use what ever you want with some slit lock washers and pay attention tightening them down. I would put a hex head on it to make it easy to RnR without damage. I would use antisieze on all threads that you put non original bolts into-though it wouldn't hurt them either. I can pick out the size, but don't remember what it actually is.

Thank you, Oreilly didn't have any but I'll get whatever the hardware store has tomorrow for those two M4/7 & 5/8; maybe do hex or black sockets for everything later.

If you can't find them, try McMaster-Carr. http://www.mcmaster.com
