I also have a Chonda which has had both those problems at various times. The fuel dripping was a small piece of rust between needle and seat which comes from a rusty bottom of the float bowl. I just cleaned it and scraped the rust off the float bowl. No further problems.
The choke issue also happened. Just stiff and not coming on properly. I just sprayed all the linkages with WD40 or similar. Now I do make sure the choke is fully before trying to start. Sometimes have to push it a little further on. They will not go unless the choke is fully on.
I had the starter issue as well. I just lubricated the pawls on the starter so they fly out properly.
Other that that its been great and usually very easy to start.
All the best
Jeff
