I have a Keeway outlook 2012 scooter and the seal p/n 150013160000 located on the crankshaft broke and it's leaking oil on the drive-belt. The seal is not possible to find. How can I use a different seal which is 1 mm smaller in external diameter? How do I fill that millimeter in a very effective way? Thanks in advance for the suggestions.

SOURCE: 2 stroke engine smokes. how do you adjust the fuel/oil mixture?

The thing with two strokes is that they smoke a bit under normal operation, and they smoke like mad if they haven't really been run for a period of time, I would advise you to run it for a while and see if that helps.

You should not need to adjust the mixture settings at all.


Hope this helps

SOURCE: Can't get Keeway ARN to start

If you did not prep the bike for winter storage with Sta-Bil in your gas you might have some clogged carb problems You say this is a scooter but the description at top calls it a motorcycle. If it's a scoot then your engine and carb are underneath all that plastic your sittin' on.If it's a motorcycle your carb is right behind the engine between ur legs. It has a rubber gas line connected to it. Get some starter fluid from your local auto parts store and spray a short burst into the air cleaner and then hit the starter button. It should start but if it won't sit there and idle youv'e got a plugged card idle jet...time for a mechanic....next year prep the bike and disconnect the battery and you won't have to buy a new one....Good Luck !!

SOURCE: oil leak -between inner primary and transmission

There are several seals that can leak in this area. You say you replaced the mainshaft seal in the back of the primary. I've seen a lot of people replace this seal only to have it start leaking immediately. The reason was that they didn't know you must lubricate the seal before you reinstall the primary cover. When you put the primary cover on with the seal dry, when the engine starts up, the mainshaft immediately goes to 1000 RPM or higher with no lubrication on the seal. The friction burns the lip of the seal up before the lubrication in the primary can get there. It only take a second, literally.

Other seals that can cause leaks in this area are the large final drive gear seal in the face of the transmission behind the front belt pulley and the "Quad" seal that is inside the transmission. The Quad seal is almost like an O-ring. It's purpose is to prevent transmission lubricant from seeping out through the splines of the final drive gear. If the front sprocket splines wear and the sprocket gets the slightest bit loose, the compression on the Quad seal will be lost and the tranny will leak. The tale tell sign on this leak is that the transmission will leak a spot of oil about the size of a quarter or a bit bigger when you park the bike. If you wipe up the spot, it won't leak anymore until you either ride the bike or simply start the engine. Then it'll leak that quarter sized spot and stop. Check your lube level in your transmission.

Whenever I pull the inner primary and the belt on a Big Twin, I replace ALL the seals. Make sure you lubricate the lips on the seals so they don't cook before lubrication can get to the seal.

Good Luck
