I use regular (87 octane) in all of my Chinese engines and I have had no issues doing it. Unless your compression is above 10:1 or so there is no need for the higher octane. Rule of thumb, if you hear pinging under normal driving conditions then use the higher octane stuff. the comp ratio on a gy6 is 10.5:1. I didn't notice any difference. I've seen specs for GY6's that go from 8.8:1 for the 150cc to 10.5:1 for the 50cc. Regardless, I haven't had any issues with running the lower octane gas in mine. |

Move the wire with the fuse holder on it to the positive connection on the battery. That's where it is supposed to be. Be prepared to replace the fuse. It may be OK but sometimes they blow and can still look good.

Simple to test the diaphragm of your petcock. Like I stated above, pull the vacuum line off of the intake manifold. If gas dribbles out it is bad. Apply suction to the vacuum line. if you taste gas the diaphragm in the petcock is bad.

Running a little rich. Check for fuel coming down the vacuum line. If not, make sure you have a clean air filter and fine tune the carb.

Look at your spark plug to see if it is running excessively rich. If it is fine tune the carburetor. if it is running too rich it could also be that the petcock is failing and allowing some fuel to run down the vacuum line into the intake manifold. You can check that by pulling the vacuum line off of the nipple on the intake manifold and looking to see if any fuel dribbles out when suction is applied.

Stethoscope maybe? Hey when I was little both my dentist and doctor gave us suckers when we were good at our visits. Or how about an old style oil can with the metal spigot standing up?

In Washington State driving a 50cc or less scooter or moped requires a drivers license but not a motorcycle endorsement. The license plate is the same as any other motorcycle or larger scooter. There is also no requirement for insurance on a two or three wheeled vehicle.
Here you can also get a DUI for driving any kind of vehicle, licensed or not, powered or not. Bicyclists have gotten DUI's as well as riding lawn mowers. If you're on the street you're fair game.

Rule of thumb; make sure the valves are adjusted properly first then adjust the carburetor.

Sameo sameo. Just find out if your valve length is 64mm or 69mm long. Rocker arm must match.

I think he means that his brake light only comes on when he squeezes the rear brake handle but it does not come on when he squeezes the front brake handle.

Does it have spark? pull the spark plug, snap the boot back on the end and hold the gapped end on the valve cover while someone holds a brake handle and cranks the engine over.
Does it have compression? While the spark plug is out hold your finger or thumb over the spark plug hole while cranking the engine. If you finger/thumb is blown off the hole you should have sufficient compression.
Are you getting fuel to the carb? Pull the fuel line off of the carb and let it dangle in a cup. Pull the vacuum line off of the intake manifold and suck gently on the line. Fuel should then run into the cup while you are sucking on the vacuum line.
Put the spark plug back in (just snug it down good. Too much force and you might strip the threads) Either spray some carb cleaner in the nipple on the intake manifold, or dribble a little gas in there and try to start the scooter. If it pops/trys to run then stops you aren't getting fuel from the carb to the cylinder.
Let us know what happens.

My money is on the fused line somewhere, or the fuse itself. If it is the original style and original holder I would replace that setup with a blade type holder and fuse. Could be intermittently losing contact at the fuse holder connections.
