Question about RTO Toys
SCOOTER STARTS FINE IDLES FINE BUT BUGS DOWN WHEN I GIVE IT SOME THROTTLE
SOURCE: no power
Keep changing parts until you find the solution! No, just kidding. Many will do this if they don't understand how an engine works. It sounds like it may be a hung choke. Engines need extra fuel when cold, and die when warm if they are still getting that extra fuel. Also, low oil level will give the same indication. There are many variables.

I just fixed one of these. Starts, but won't throttle up, sounds labored.
I checked compression, exhaust for carbon build up, spark, and even the carburator for bad gummed up gas. All were fine.
What I did to fix it was...
You need to remove the high and low speed adjustment screws on the Zama carb. They are blanks, and have no slot for a screw driver. I used a roll pin that the inside diameter fit snug on the outer diameter of the ajustment screw head, and turned it with a pair of needle nose pliers. I remove them (One at a time) and cut a slot in the head with a hacksaw, to allow for future adjustment. Back them both out one full turn from seated, and then tweek to get it to run. The low speed is for idle (Out to richen), and the high speed is for wide open throttle. It's closest to the air filter.
