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.
I went back out there and checked for spark 1 more time. This time I saw a little spark if I looked VERY closely. A little tiny yellow spark. I tried starting it for like a minute or so, nothing. I looked at the resistance of the CDI and it reads 2 instead of 7. So, I really think its the CDI.
EDIT: I noticed that the little screw on the bottom of the carb was really loose, also, the carb should be fine, when I push the primer down gas goes to the engine, and it flows out too. I think the oil problem is no big deal but tell me if I am wrong. I did add some more gas to the mix to thin it out a little bit, so that should be fine now. The new CDI is supposed to come in tomorrow, so I will keep you updated.
 
probably only needs carb, fuel line, fuel filter and tank cleaned out to start it up

oil in carb is bad, gums up jets, .. your spark issue is either coil , wire, ground point. cdi, point , condensor . keep trouble shooting it. replace the parts, IT WILL RUN!
 
I used to have a honda pa 50, it always fouled plugs, my bike now is just used to go up and down a hill road very steep 2 miles...up 1000 ft so it gets a serious grueling stress work out daily.oil is changed monthly black .. tires on this gem .toasted every 6 month 2.50 x17. so i went up to 3.00 x 17 michlin from IRC , 1 year now. better that extra 30 is worth it! folks RIDE ON
 
the best bike i ever rode was a penton 360 ; 60 mph in first gear at the old dump riding grounds. trench digger bike. saw it beat a suzuki rm 250 with ease

I did the same thing at a Gas Station I took out care drain screw and let fuel run through a little put it back in and got it started after a couple of tries
