I'll see if I can supply enough information to make sense I have a CZ 175 from 1973. Its a kick-start. The problem I'm experiencing now is; after I start it and get it running, it starts to choke up a bit and eventually I am pretty sure flooding. I'll be riding along and it will just loose its power and when I gear up it just slowly stops. I've adjusted the idle screw, as it seemed there was a problem with it idling but now no problem, but it now floods (I think anyway). There is also adjustments to the fuel injection that I haven't played with. So why is it flooding? Is there anything else I should look at? I'm reading the manual now, I'll post anything that could be useful.
