Well, I don't have anything new to report. It has run well for 5 days in a row. The last thing that I did was clean out the gas cap and make sure that it was breathing. Of course, I only run it down the street and back each day. Hoping to run it a little further in the future. Thanks, again, for the help! I'll keep everyone posted if it starts happening again!

The battery is a few months old, but I'll charge it today, just to make sure that it's fully charged. As for the throttle, if it's running well, it's fine at all throttle levels, and if it decides to spit and sputter, it idles great, but acts up on full throttle, all the way down to about 1/4 throttle. At that level, it can putt along without issue. I'm wondering if I could maybe have some trash in the tank. The first thing I did upon receiving the bike was to completely empty the tank, and it seemed to be clean, although the gas that was in it was probably several years old. Or maybe I should try completely cleaning the original carburetor and putting it back on. The carburetor I have on there now is new, but was fairly inexpensive.

Well, oils have been changed. The motor oil was disgusting....probably never been changed. I started it up, and it up, and the rpm's were much higher than before. I just figured that it was because the oil was so thick before I changed it. I adjusted the idle speed, and took it for a spin. Once again, it was spitting and sputtering like before. I didn't have time to fool with it. This morning, I had planned to open it up again to check things out. Before doing that, I removed the gas cap, thinking that maybe it was clogged. I cleaned it up, and blew through the outer hole with success, and I put it back on and started it up. I gave it a quick ride down the street, and it rode well. I'll run it again tomorrow, but these days, it just seems to start spitting and sputtering without notice. I only ride it down the street and back each day, nothing more. I bought it as a favor to a friend who was in a bind, and don't plan on keeping it. I don't want to sell it, however, if it's not running well. Any idea of what I could check out if it starts acting up, again?

Thanks, so much, for the great information! One more question, if it's ok......where is the drain and cap to drain and add gear oil? Thanks, again, for the help!

Well, I adjusted the idle mixture screw by turning it in all the way, and backing it out 2 1/2 turns as a starting point, and adjusted it from there. I added more fuel (it really doesn't like to run on less than 1/4 tank or so) and added a tiny bit of Marvel's Mystery Oil. Between those 2 simple things, it is running better than ever before.
I'll be changing the oil, soon. What type of engine oil do these scooters use, and approximately how much? Is there a drain plug? Also, is there any transmission or gear oil that I would need to check or change? Sorry for the constant questions.... Thanks for your help and patience!

I'll check the carb float level and idle speed settings, as well as gas tank gunk tomorrow....I'll report back as soon as I can.

I've been working on a JCL 150 for quite a while. It had been sitting for years. It's a 2007 with 770 miles on it....that's how long it has been sitting. I changed all fuel lines and vacuum hoses, bypassed the charcoal canister which was cracked, installed a new carburetor, and installed new brakes. It was running fine, but suddenly began to hesitate at the beginning of giving it full throttle, then catch up. I couldn't find any vacuum leaks, so I made a very slight adjustment to the carburetor float (I thought maybe it was starving for fuel). Now, when I give the gas, it really spits and sputters horribly. I also noticed that the carburetor idle screw doesn't seem to make much of a difference at all. Any suggestions on adjusting the carb float and idle screw? Any other ideas as to what may be wrong? I guess I'm not entirely convinced that it's a fuel issue. Thanks.

I have just completed a few repairs on my scooter, including replacing all vacuum and fuel lines, removing the charcoal canister, new fuel filter, and new carburetor. The only issue I have now is that it hesitates slightly just a second or two after full throttle. After the hesitation, the rpm's climb right up and it is fine. Any suggestions? Thanks!

All of the above changes have been made in order to remove the charcoal canister (it was falling apart). Now, the scooter has a slight hesitation right after full throttle.....sort of a quick drop in rpm, and then gradually builds back up to speed. Any thoughts? Thanks!

Now that the canister has been removed and lines routed as in the pictures above, I find that the only issue that I have is a slight hesitation upon takeoff....It just lasts a second, and then the scooter gains speed as normal. Any thoughts? Anything you would do differently according to my photos? Thanks!

As soon as I can open the scooter up again, I'll take pictures. I've had trouble uploading pictures here, but I'll give it a shot! Thanks! Also, I put a fuel filter in the hose coming from the valve cover, and mounted it higher than the valve cover, itself. I got this tip from 2 different sites.

Well, I've watched hours and hours of video and looked at tons of diagrams on the subject....just wanted to make sure that I didn't mess anything up. I plugged up the hose coming from the intake manifold going to the canister. I put a fuel filter on the gas tank vent hose, and left the large hose from the air box open. I put a fuel filter on the valve cover hose, and mounted it up higher than the valve cover. I was then able to remove the canister, which had been zip-tied on because the rubber mount had cracked. Everything else was left in place. It seems to run fine, with no bogging down or hesitation. Thanks, everyone, for the help!
