A lot of the problem stems from the fact that the carb is encapsulated (anyhow, it is supposed to be) in the right-hand cover where no dirt can get at it and also where the rider cannot see it to check it out or louse it up as the case may be. There are a couple of problems that crop up that the owner may not be aware of that can be checked quite easily with a minimum of trouble. One is whether or not the carb area is sealed off from dirt and dust or not. Another is one that is seldom noticed, it is the fact that the machine has never been able to get full throttle because the oil pump cable stops the throttle assembly before it has a chance to open the carb completely.

A very large crowd came and it proved to be very exciting. Backstage, stalls and corridors that were built long ago for show horses, prize cattle, bucking broncs and rahma bulls, to nigh t were filled with motorcycles and men clad not in Levi's and pointed heel boots, but in leathers and hot shoes. It didn't take long to get the picture here tonight. And that is, that Mike - Kidd sure can ride that BuL In one heat, he somehow got a bad start and was in back of the pack. Didn't seem to shake him a bit, he coolly and methodically picked 'em off aile by one, it was as if he knew precisely how much time he had to spend on each one to pass him, then move on to the next. A t the end of the last lap, with not a -. second to spare, he passed the leader just a few feet from the finish, and took the win. Mike took the win in the trophy dash, the 200cc class, and in the 250cc class. He is only 17-years-old, but has been riding cycles since he was 5.

They both rode Y'!maba Mini Enduro's. They evoked huge laughter from the crowd when Randall, having made it safely through the whole race without a mishap, following Markie Baby over the finish hne, spilled and slid on his backside for about 30 feet. He was unhurt, however.
