Greetings to a fellow neophyte:
I too blew the carb off my bike when I used the micarb round slide carb. I never could get it back solidly onto the cylinder and the performance wasn't very good either. Sometimes at a stop, waiting for a light change, the engine revs. would begin to in crease even though I didn't twist the throttle. Long story short I didn't like too much about the carb so I got a 30mm flat slide from our hosts. Best move I ever made. More power and performance than ever before.
Also starting became much easier. By the way, easy starting with the kick start is to use the enricher to get some fuel into the cylinder to begin with leaving the ignition key off. To make it easier, activate the decompression. Several kicks all the way down and through will get gas into the cylinder where you want it when you turn on the ignition and lift the kick start lever to begin the start stroke. Then with the cylinder partially filled with a fuel charge, the de compressor activated and the ignition on, push the kick start all the way down, until you think you will strike your shin on the foot peg, then you can stop pushing down. The engine should fire and continue running at a brisk speed as long as the enricher is used. In a few seconds, you can stop the enricher and let the engine warm up until you've checked lights, tires and are ready to get your gear on and ride off.
I also dumped the points ignition because my eyesight was poor and setting them in that tiny dark housing was beyond me. I have electronic ignition now and I don't have to constantly fuss with it. I ride instead.
Best wishes and ride safely.
