Been noticing lately I lose power at different times, felt like my brakes were on even though the engine is revving. This morning I started my super 8 50cc and let it warm up, but it would not get any speed even coming out of the driveway. I decided to get a ride instead of having to push it to work. Again, the throttle revs fine but the wheel does not spin even with the center kickstand down and the wheel off the ground. What's my problem???

So I assume most of you are buying 93 Octane or better to put in your scooters or other small engine vehicles.  When I get gas, I'm usually getting about 0.75-0.9 gallons, since my tank is only 1.3 gallons. So even though I'm selecting 93 octane at the pump, am I not actually just getting whatever gas the last guy selected that's still left in the hose? Am I actually even getting any 93 octane at all since I'm pumping such a small amount? Does anyone know a definite answer to this?

I've been reading all these posts on here, and I'm not a mechanic by any means, but on my Super8 50X, I have managed to cut the pink wire on the CDI box which gave me higher top speed (37 downhill). This morning in a desperate attempt I did manage to get the carburator separated on the left hand side (front) and dug around and found a metal washer about the size everyone's been saying, so I took that out and put the carburetor back on. I took it out for a small test drive, couldn't really find any good hills and I have to be at work today, but I didn't seem to have that much more power. Still going 25, creeping up to 30 on flat road. Does this sound right? Did I get the right washer out or am I just removing random parts?
The uphill problem seems to be getting worse and worse. Like I said, I was desperate this morning after backing up traffic at 5mph uphill on the way to work, any worse and I'll have to push it! Am I putting the wrong gas in? I'm just using regular. What do I need to do, or tell a mechanic to do?
