Well pretty much I bought a g3 that was a complete basket case, seized, no throttle, etc. Anyway, I had to free the piston, and since the sachs doesn't have a head I just used a breaker bar on the flywheel and a ton of pb blaster. pretty much it ran for a while, but the clutch was stuck so it couldn't idle, until I freed that too, then the clutch was real slippy, but it ran until there was a trouble in the case and when I took the cylinder off the rings were totally trashed so I had almost no compression and I think that made me four stroke hard. Loose the air box for sure, you loose your choke, but its worth it. Get like a uni pod or something, and I am with the other guys when they say get a bing or a dellorto or an amal for it, it will make your life a lot easier and ones can be had for cheap. Sachs jets are just too hard to get and if you buy like 5 of them you could have just bought a different carb for the same price.
