I just received my 80cc motorized bike kit in the mail. I finished assembling it last week. There are two concerns I have. The first one, when I was mixing the fuel, I poured 4oz of oil into the gas tank on the bike, I didn't notice that the petcock (fuel valve) was open and continued to pour the gas. Some oil went down into the carburetor, is this OK? Concern number 2: I verified that I have done all of the wiring correctly, and there is no spark on the spark plug. I checked the magneto, all was well in there. Then I replaced the spark plug, no luck. At this point I have ordered a new CDI (capacitor discharged ignition) in hopes that the thing will get spark. Any help on this problem would be appreciated.
