The more gas worked. It is running. Now for the new problem.......
Now that she is running better, I have found that she still has trouble starting, but not as bad. When I first took her apart, I didn't open the air box, I just took it off. After some time and realizing I missed checking to see if the filter was clogged, I opened the air box and oil poured out of it. Now that the box was off I noticed smoke coming from the carb, but a very slight smoke from the exhaust. I was thinking the smoke was from old bad gas. With the compression at 120 and the oil in the carb and air box, I am thinking the rings are going or have gone bad. This would be the reason for the hard starts. When she is running she runs fine but has a bad idle, so I am thinking the more she runs, the more oil I believe gets into the carb and compression chamber. Thus making it harder to start. Just confirming before tearing the engine down and replacing the piston, rings and cylinder?

Timing is TDC and valves are adjusted. When I put the fuel down the line as suggested, she wants to start, but once the fuel runs out she doesn't. She almost wants to turn over but just doesn't get to that point. Any other suggestions?

Put the fuel down the suction line into the intake and she did almost start. She seemed to speed up like she was going to start and then just wouldn't turn over. I am going with adjusting the valves next. Had to stop and take a break. Thanks again.

So here is what I got as to how it stopped running. My friend was riding along and it sputtered to a stop. He looked inside and saw that the fuel suction hose had broken off. He put the copper tube back into the hole and reattached the hose. It did the same thing. He then parked it for a month or so. I replaced the intake with another one and the carb. I tried putting fuel directly down the hose and that did not work. When the battery is recharged I will try the timing and see if that is off. Will also look at the valves and see if they are out of Adj. Thanks for the quick response and if you have any other ideas. Two strokes are easier I think??!!

I am working on a Q139 50cc Chinese scooter. I have spark, fuel, 120 on the compression and exhaust is clear. She still won't star. New intake installed after the fuel suction pin broke off. Tried all the tricks, carb cleaner into the spark plug, into the intake directly, NOTHING.
ANY ideas?

Thanks for the replies. As for more pictures, more are on the way. I had to stop working on it for a bit, but ordered some new parts. Once I get some tires under her, I will post more. Right now I am looking for a speedometer. Any hints as to where I can look for and get that would be great. I hope to get these things noticed. Down Here in Fort Lauderdale, I would love to see more on the road.

Got the first of the two scooters running. Thanks to Alleyoop for the lean rich page. It was right on the money and she is running like a champ.
Second scooter had a slightly different problem. He was riding it and he slowly started losing power until it stopped running all together. After some tinkering, it had spark, it was getting fuel and this morning she actually coughed some. I was hoping I was on the right track. She suddenly got harder and harder to crank. Now using the foot crank, she doesn't move. I was at first thinking when I adjusted the valves they were too loose and not venting properly. But I took out the spark plug and she still isn't moving. Frozen motor? Blown motor? Compression tester comes in on Thursday, but I am thinking the worst. Worth rebuilding? Some more help here is very much appreciated.

Ok, got it to start and rode it for about 15 minutes. ran ok, knowing it needs an oil change and some carb tuning. After riding it it now idles and runs ok, but give it some throttle and she shuts down. I am sure it is all about what you last posted about turning the screws. New plug in it. I will play with adjustments until she runs ok. Just wondering why she was cutting off when giving her some throttle.
Thanks.

Ok cleaned the carb and poured some gas down the intake and she almost started. Coughed a couple of times then died. Sprayed some carb cleaner into the carb and again she coughed. So now what? I am getting drops of fuel down the line when craking but it seems nothing worth starting and keeping her running. ANything to do about making sure fuel is steady enough to run? AGain, thanks for all of the input, it all seems to be helping.

Ok cleaned carb completely. There is spark. Not sure how strong it is. I can see good spark in the light while plug is out. Tried taking carb of and dropping some fuel down the intake and it still didn't start. Next is compression. Can the compression be the problem and what does it have to be at. This actually the second of two scooters with the same problem. One he was riding and it quit. The first was sitting for a long unknown time. I need to get at least one of them running. Any new ideas? Bad CDI? Out of time? But no timing with a CDI I believe. I am used to two stroke. Any Help???

Here it is as of last week. Once it is all back together I am going to build a side care for it, hopefully it will be kitted and have more power for the side car. Attachments:

Does anyone know if there are any kits for a 1965 60cc Allstate Compact ? I am rebuilding one and would love to kit it out and make it fly. I was told they can't be kitted out, but I just have to believe somewhere out there, there is a kit that can go on this motor. Any ideas?

This seems all to familiar. I did this with my Puch mopeds and they are now running great. When I had the carb off, I didn't even think about tearing it down. It just slipped my mind. Fuel is flowing good through the hose and out of tanks when I crank on it. I will be changing the plug tomorrow and tearing the carb down to see what it looks like. Thanks for the help........
