Cleaning up nicely. Got the carb looking good...lotsa, lotsa varnish. Gas tank cleaned up nice. Cleaned the petcocks...lotsa baked on grease/dirt. Degreased and power washed the engine/chassis. 30 years of backed on grease. Will take a lot of detail cleaning to complete the job. Engine is free. Can't say the same for the clutch. Reinstalled the carb and fed some gas/mix temp. Did fire a couple of times, but I need to get a manual before I start tinkering with ignition etc. 'Tis a beast to turn over, lots of compression. I also want to do a full leak test before I go too much further (seal exhaust, build a test gauge/pressure valve for the intake to test seals etc.)
11;00 UPDATE: We have sustained fire. Won't idle. Need the manual (Ebay - shipped today), but proves out the ignition/spark. Clutch plates freed up. Ran just enough to blow out the spark arrester and fiberglass. Needed cleaning anyway. And upset my wife & her favorite 10-11 show plus the horses across the way.
Lesson for the day. Put on your MX boots before kicking this beast over.
Update 4/9/12 Received a rebuild kit for the Amal 392 that I was waiting for. Pulled the carb back off and as I suspected, the Pilot jet was clogged which was why no idle. Notmuch to the rebuild kit, Just a bowl gasket, banjo bolt gasket and two orings for the idle and idle mix screws. BUT now it runs, starts easy, idles, and the idle mixture screw works as designed! Just the temp fuel feed so I did run it under power on the driveaway before the temp fuel source gave out. I will have to remount the tank, air cleaner, seat to give it a better go then set up to do a crankcase air leak-down test to see how the crankcase seals are and move this to its own thread under 2-smokes.
