<HTML>Well, it would help if I could spell. In my other message, I misspelled the name of the model.
I since learned from Sean at Myron's Mopeds what kind of spark plug to use. Mine was fouled and the carb needed to be cleaned. It runs only at full throttle and his best guess is that the muffler(a large flat box under the motor) may be clogged. I will remove it in the morning. I will also check the carb jet for correct size.
Any other input from here would be great. I have no manual etc. on repairs for it.</HTML>
