What wattage bulbs are/were in it? That looks like something that would happen if running too strong of a bulb.

Well, I have no clue as to what's up with the electrical, but I can tell you that the first issue you mentioned about the starter not wanting to engage is most likely due to a worn out starter Bendix. It is a small gear located inside the cvt in the upper front end. Once the cvt cover is off it can be replaced by hand as it just slips out and in. www.partsforscooters.com/151-41-Starter_motor_clutch_qmb139 |

I have heard that .005 is a bit much for a valve lash (even though it's a minuscule difference). But I'm no pro at this.

Guess I'm one of the lucky few then. I have a Tao Tao cy50-a sport (VIP). I haven't had any issues with it that weren't caused by situations beyond my control (other drivers pulling out in front of me/getting over while I'm beside them).

Also, make sure the idle air/fuel screw is about 2 to 2 1/2 turns out (counter clockwise) from all the way in.

I would check for deposits in the jets. Also, the screws don't have to be in tight. Just snug. If the sputtering continues you could try adding some Seafoam to the gas tank and running it through. Use 1ounce per gallon. Other than that you should be good.

Pb blaster or Deep Creep could help make the job easier. Or if you can't get it out the other way you could always drill it out. Just be careful with the threads.

As for the jetting, I know that no2 scoots are created equal but my taotao VIP 50cc ran like a dream after I put a #82 main in.

You could try taking a hacksaw/dremmel and running a groove across the head of the screww and using a flat head to gently back it out. I had the same issue with 2 carbs and ended up taking it to a mechanic and giving him $10 to get it out rather than causing myself a headache. I would go ahead and buy some tougher screws though as the ones they ship those carbs with are made of soft crappy metal.

Is the carb they sent you sealed? And what sizes are your main and idle jet respectively if it is not? They say that the Chinese scoots are notoriously lean so you could possibly need to upjet.

I had a Tao Tao that did something similar. I found the cause for my issues to be a faulty fuel petcock. The diaphragm in it was sticking so I removed it, plugged the vacuum line that went to it and installed a manual fuel cut off valve from Briggs and straton. But you could just replace it as they bare cheap.

They must think these scoots are disposable then.

I believe the general rule of thumb is two sizes per mod.

Just bought a few different plugs yesterday and tried them all out on 5 mile runs each and I can attest that these plugs progreengrass.com/spark-plug-cross-reference-chart/ are the exact same with absolutely no change in performance (at least on the short term). Just a couple dollars difference for the brand names, that's it. I needed a few spares anyways... |
