Hi everyone, totally new to owning a vintage Vespa. Picked up a 1977 Rally 200 a couple months ago that had been sitting for a number of years (the sticker on the plate expired December 1981), it's a bit rusty but solid. I've been looking online (quite a bit in this forum, thanks!) for tips/instruction as well as talking to friends with Vespas (but don't live near me).
The body was stuffed with a mouse nest, and the air box was their privy, pretty crusty in there. Cleaned up the carb and box pretty well, but the arm on the auto lube cover was solid in place. Took it off, sprayed it with penetrating oil (didn't work), soaked it overnight in penetrating oil but still couldn't get it to budge. So I ended up using a bit more force, eventually got it free.
Reinstalled auto lube cover and carb. When tightened down (not over tightened though) the auto lube arm doesn't spring back. It moves fairly easily, but that is it. Should it spring forward on it's own when installed?
I connected the throttle cable and gave it a quick test to see if the throttle slide would be enough to bring it back. It opens ok, but doesn't return. Throttle slide on carb snaps back nicely on it's own, but when fully connected, no dice.
The throttle slide rod appears to not be pulling straight out and I suspect that is why it catches. I assume it should more or less pull out straight. I thought maybe I had bent the auto lube arm, so I ordered a new auto lube cover, but same problem. Could I have installed the auto lube cover incorrectly? I'm having trouble finding anything that shows me how that should be done. When I took it off there was just the cog and a spring under that. I'll post some photos below.
