Hey guys, I am new to these forums and scooter repair, so please bear with me.

This whole thing began when my scooter was having issues trying to cold start. But when I start it again while the engine is warm then it starts right up. So I suspected that some possible solutions were: cleaning the carburetor, replacing the choke, and adjusting the valves.

I took off the underseat storage and did some visual inspections. One of the first things I saw was the air intake tube was cracking and breaking apart. Maybe that was causing the scooter not to start? So now I gotta replace that intake tube. And the carburetor is located right under it so I had to take it off regardless.

The first thing I decided to do was to do the valve adjustment. I watched many Youtube videos on how to do this and I thought I was well prepared. I took off the engine head as instructed, removed the 4 bolts. After that, things did not go as I planned, it actually has caused me more problems to deal with!

First of , after using the feeler gauge, I was tightening down the bolts on the valves , but the inner screw just would not stay put when I held them with the pliers. And then I found out that screw has been stripped , in other words it won't screw to the hexagon nut. The second problem was that I was being so clumsy (I was working outside in the summer heat) that I've accidentally dropped a screw into the camshaft hole. So I've had to try disassemble the rest of the engine head, ended up removing more screws and bolts , since there were so many tight spots my wrench wouldn't fit unless I removed part of the plastic frame.

This whole process took me a few days to get through. I've already removed the camshaft off of the chain , removed the muffler bolts that were attached at the bottom, removed the manifold, along with many other screws, then I was able to take off the head. But now I've reached to a point where I'm suck.

There was another hole I found what seems to be the inside of the oil compartment, the screw must have fell in there. Well f**k! I've done all that removing engine head for nothing.

So I drained the oil out from the engine , and now I just need to figure out how to get inside the oil compartment to get that screw out. This whole thing has become a hassle now, what I thought was going to be simple and easy turned out to be a nightmare. At least from all this I've gotten the opportunity to learn more about my scooter.

Hopefully somebody can help me with this what else I need to do. Preferably someone who's had a lot of experience and knowledge with Chinese scooters / GY6 engines. In the end I hope I can revive my old scooter, do a few modifications, and make it like new again, even better!

If anyone needs pictures or anything , please let me know.
