Hi All,
I picked up an very used (but mostly running) '87 this past July, and have been gradually restoring it. When I got the bike, it didn't have the airbox or connector tubes, so I bought one of the metal-mesh cone filters and hooked it straight to the carb. Following Balderdash's suggestions found here
http://suzukisavage.com/cgi-bin/YaBB.pl?board=RubberSideDown;action=display;n...,
I stepped the pilot up to a .055 jet.
When I put the carb back on the bike, I got no idle unless I had the choke pulled out to the first notch - pushing the choke all the way in would idle so low that the engine would nearly die. I drilled out the cap over the idle-mixture screw, but the screw was varnished in place, so had to drill it and use extractors, then replaced the screw, spring, washer and o-ring. (Does the O-ring go ON the screw, or just in-front of the screw in the hole? I put mine ON the screw.) With the new screw, I fired the engine back up, and tried adjusting it, but it seemed to make no difference at all when I'd tweak the mixture screw - from all the way in to 3 full turns out, the non-choked idle was still near stall.
SO I removed the carb again, disassembled it (except for a few of the air jets), and blew an entire 12 ounce can of carb-cleaner through every orifice and hole I could find (including the airjets I'd left in). I put the carb back on yesterday, but the idle is still so low the engine dies, unless I use the choke. It runs pretty well on 1/2 choke...
Can anybody offer any suggestions? The Clymer says not to use wire to clean out the orifices, but I'm starting to wonder if maybe I've got a piece of brass or something (from all the drilling) stuck somewhere in the idle circuit that blowing-out won't remove.
Thanks for any advice,
Dave
