What is the best way to take the carb off and clean it? Are there any good guides I can print up and go by? here is a great video that shows how to clean and explains how a carb works. it is not the same carb as you have so some of the parts won't be in the same position (like the air/fuel adjustment screw). taking the carb off the engine is really easy. remove the 2 nuts holding the intake manifold, unscrew the bracket holding the air box/filter, remove the fuel line (assuming your petcock is working then only a few drops of fuel need to be drained into a container. otherwise you may need to crimp the line), unhook the automatic choke (you can unscrew it from carb or unplug it. i unplugged mine since the screws were too difficult to remove). you will then need to drain the fuel left in the bowl into a container. (remove the drain screw at the bottom of carb) once you get the bowl cover removed, the only thing i took out was the 2 jets. as long as the float appears to be working properly then you shouldn't need to remove the float. spray every tiny opening you see (wear eye protection and rubber gloves)). I adjusted the valves, now I bought some service manuals for this type of engine with the crank case housing, the only issue is the .003 valve feeler gauge. I went to Advanced Auto and the smallest gap I could find was .004. However, the service manual I have says to gap it at .005 each. Now I adjusted this thing to .005, put it all back together, and rode it a little bit. It seems to run fine with .005, but, I can hear the rockers ticking so I'll have to readjust them again this weekend coming up. Me being the redneck that I am looked online for the thickness of plain copy paper, and found that it is .001, now if i fold paper on itself 3 times it should come out to .003, which will give me the thickness that I need to gap this somewhat more properly. It getting dark so early really makes it a pain to work on things without a garage to work in. I may have a friend who's dad might have the right thickness, so I'll find this out sometime during the week and see if I can borrow it. As of now it starts with starting fluid, but I believe the .002 more of a gap than it should have will give me trouble starting it up. But I will try my best to manage for the rest of the week getting to and from work. Hopefully I don't have too many problems with it. i think i have the same feeler gauge. i just adjust mine to .004 and it runs great. (i think the .005 spec is for 150cc) seems like slightly loose valves are better anyway. when your valve clearance becomes tight then it is hard to start and you will lose top speed. |

Your carb has the Fuel Ratio Mixture plugged you can either drill it out or get an aftermarket carb which do not have them plugged. Alleyoop  |

I don't know what's going in with this thing.... but it is pushing way too much oil out of the valve cover into the intake..... like so much if u push it down oil pours out of the intake hose

If it's oil, how much did you put in? The first oil change I did I added too much, and ended up with oil coming out that valve cover vent tube for about a week and a half. I took alleyoop's advice, and added a fuel filter to the end of that line, then zip-tied it to the frame higher than the valve cover. Haven't had any issues with oil coming out since.

Rick, I read about your scooter dilemma all the way to the end. Very informative and of course you cant get better answers than Alleyoop. However, the one answer I wanted never got answered since it was at the end of my page. The question was-- What is the spark plug gap? So please tell me the answer.
