I usually get my body kit parts from - www.scrappydogscooters.com/CHASSIS_PARTS.html - they may not have what you are looking for, but they have a lot of different parts. Just choose the style of scooter, and scroll until you find something. Otherwise eBay is the only other place that I can think of. |

I did it 3 times this last time, sucks to do it again, but at least it doesn't take too long to set them

Ok, I will try the bigger gap. I have used this gap on 3 other 150's with out problems, but at this point I am willing to try anything. Thanks

I thought of the plug as well, it was dark, but I used fine grit sand paper to clean it, and even switched it out for one fresh out of the box, but same thing. Great thought.

Ok, I was sure that I did have it at TDC, but I will check again and make sure that it is TDC and see where it all lines up.
Thanks again! I will post after I check all these things

I will take a look, but it seems crazy that the carb would work just fine on the other scooter, but not on this one. I was able to do all of my adjustments on the last one with no problems, but this one just refuses to run no matter what I do. Let's say that it isn't the carb, that all the jets are clean, all the different ports are cleaned and that I ran it through a parts bath for 15 minutes straight, but it still does the same thing. What would be next to test?
(I will check the carb again, and also the compression) Thanks heaps for the help, giving me good ideas

It idles just fine at 1500-1600ish until it is warm. I thought the same thing with the idle adjustment, I even had the idle set screw all the way in at one point, but it still ended up stopping.
With the fuel ratio screw, I have been playing with that as well, but it doesn't seem to be making a difference either way.
i pulled the carb and auto choke off of a scooter with the same engine setup, that I did a crankshaft replacement on, and it was running perfect when I pulled it off. So I know the carb works and is clean

I am currently working on a sunl 150cc scooter, and the customer said that it was working when he got it, but that over time it has stopped working. I was told that he was driving it to work and back (about a 15 min drive, including a brief stint on the freeway). I originally thought that it was a carb problem,and so I cleaned it out. That didn't fix it, so then I saw that all his vacuum lines connected to the fuel valve switch, and the gas line went right to the carb. I changed everything back to how it is supposed to be, and then found out that the intake manifold was cracked all the way through. Changed that out, and it started up and ran until the stop sign where it would die at idle. (Then the belt shredded, and had to be replaced) So I adjusted both valves (0.08mm) thinking that it would do the trick, because I have had that issue on other scooters and that solved the problem, not on this one. It will idle until it is warm and then die. I can even rev it up during this time, and it will bog for a split second at first, then pickup and go like it is a carb adjustment problem, until it is warm and then it dies and won't start until it is cool again.
So I have tried EVERYTHING. I replaced the vacuum lines, carb, intake manifold (same as mentioned above), automatic choke, spark plug, ignition coil, CDI, fuel lines and filter, adjusted the valves (as stated before), and still nothing.
Is there something that I am missing? I am planning on doing a complete top-end rebuild; cylinder, piston and rings, gaskets, and valves. But before I spend $150+ on that, I want to make sure that there isn't something that I am missing.
Any help would be greatly appreciated! thanks
