ok thanks. Ill look at that as an option. In the meantime, thinking I would have to take the whole engine apart, I fired it up after getting the valves adjusted according to Haynes manual (.006 intake, .008 exhaust) Seems to work fine for now. Im still worried about that nut going someplace it shouldnt though. Maybe a project for next weekend.
Thanks for all the help.

I left both valves too loose and there was a bunch of clacking and 10mph max speed. I went 20 yards then turned around and went back to the garage.

Thanks for that Aoop. It looks like from some videos that the nut can only be with the timing chain. Since there is a plastic shield below the timing chain- and since I inspected the chain and it looks perfect- it seems like the only place it could end up is below the plastic guide for the timing chain within the metal box that is the camshaft/crankcase? Is this correct? Is there nowhere else it could fall into? So, Ill keep digging around with the magnet and maybe shaking things around to try to get the nut to fall into a place where I can grab it? Apart from that, do I start removing the crankcase? yikes!
This is a cool look inside:

Thanks for the tip Allyoop. I went and found a telescoping magnet and stuck it all the way in (9 inches or so) and didn't feel the screw. I also drained the oil thinking it may be in there. No luck. What next? open the stator? Any other idea?

I did my first valve adjustment and must not have tightened the locking nut on the exhaust enough so now its missing! The adjustment screw is still there. I have no problem running out to get another nut but I think it could be dangerous having that moving chain and various other moving parts and a nut dancing around in there.
I don't see it on the floor or anywhere it could have fallen to OUTSIDE the engine. Sooooo, how do I get in there and get it out? Maybe I should get a strong guy to come over and we can shake it on its head and hope it falls out? Do I need to take the whole engine apart to find it??? Help!
Thanks

Alleyoop that's an apt handle. You threw it up and I knocked it down. Turns out the clamp was bent allowing some air in through the auto-choke. Bending that back into place worked like a charm. So, I took the scooter to the auto parts store and picked up some grease to seal the deal. Thanks! J

I have been trouble getting my 50cc GY6 scooter to start cold. A bit of carb cleaner in the intake does the trick. Runs great and between 30-38 mph top speed depending on its mood. Starts again after a short break consistently but, once it cools down it won't start again.
When it won't start it doesn't matter whether its kick started or electric started.
Ive been all over getting this (new to me, very few miles, but 7 years old) scooter to start for me. I got a new battery, got a battery tender cause all the attempts to start drained the battery, cleaned the carb, put in and verified a new spark plug, changed oil and tranny oil.
When it won't start I can take off the automatic choke and stick my finger over the hole and it starts no prob. I verified that the choke works and it does. The pin on the choke starts at 3/4 inch or so and extends up to an inch. Resistance across the leads is 24 ohms. Seems really high! Maybe the choke is the wrong kind for the carb? Though I have no idea how to check.
So what the heck!?
Im thinking MAYBE I failed to get something out of the carb? But its really clean inside. I think the guy that sold it to me put a new one on.
I don't have a gauge to check compression. I would have to take it to a shop or buy one.
I don't have vacuum hoses to check. I see a bunch of posts about that. Some people enjoy sucking on them. The petcock sits at the tank and runs directly to the carb through an inline filter. I suppose I could try changing out that filter? Though gas pours out when I detached it from the carb so gas is getting to the carb.
Doh. Owning a scooter is pretty fun...
