Congrats, you have the most evolved of the SOHCs. I have one also. You should take you time and really clean the carbs very very carefully. You have an accelerator pump which tends to varnish up badly, there is very little fuel in it so it spoils quickly. You should locate the shop manual on this site download it and follow it. They will tell you the slow jets are pressed in, but they can be pulled out and they need to be cleaned well.
Good Luck,
Bobby
