I'm not convinced that's a such good idea. These scooters are not unlike ultralight airplanes with 2-stroke engines. When running on gas/oil mix, they'll run out of oil while descending at part throttle, thereby scoring the heck out of their nice shiny expensive pistons. So ultralight 2-stroke engines use an oil pump to ensure a good oil supply during downhill part-throttle ops. It would seem to me that scooters can run out of oil the same way as ultralights can. On the other hand, running an oil pump PLUS mixed gas might cause an over-oiling situation, thereby explaining the oiled-up silencer and puddles of oil in the crankcase.Wheelman-111 wrote:I might recommend the economical way of eliminating the possibility of a faulty pump by tossing it in the bin and obtaining a plug. It can cost as little as $2.17 in US Currency , but VT Cycles sells sells a ready-made one. Then run 32:1 premix and that leaky pump issue goes away.
BTW: earlier in this thread, the OP asked what's in carb cleaner. Answer: toluene. It's cheap, $7/litre at paint shops, and it cleans all the crusty crud out of your carb if you soak it overnight. You'll be amazed how much crud comes off. Disassemble everything, and only soak the metal bits, though. Blow the jets out with a WD-40 spray bomb.
