2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the choke.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.

Try eBay or a motorcycle part finder site
And on the problem of it reoccurring difficult to say as need to know what damage was caused to piston and valves
Was it just one rocker arm that broke or is the other damaged did the timing jump and piston hit open valves driving them up and breaking arm and damaging cam shaft lobes
You really need to find out why and how it happened
As it may require a complete timing system replacement on that cylinder cam shafts , rocker arms , valves ,drive sprockets top and bottom , drive chain and a piston

Find exactly where the fluid is leaking. It could be simply a fractured line. Is your oil okay? If not diluted with coolant then unlikely to be the head gasket. Not down on performance? Again unlikely it is the gasket.

There is one sparkplug at center front of engine and one at center rear. They are fairly easy to change. Just follow your spark plug wires.

Did the vehicle set up for a long period and did you use a fuel stabilizer in the fuel.

Hi, John for this scenario you will need your service manual that has all fastener torque specs -fluid capacities and a wiring diagram on the back pages, parts fiche, and owners manual if you can not find the best tool you ever bought for your Kymco, despair not, for a mere zero $0 you can download another one.
