I'm not sure what model carb you have? (the main styles are the single cable NT style or the dual cable CNS style carb) At any rate, the needle does not have much effect over the mix at 3/4 throttle to WOT, so adjusting the needle to cure the WOT bog is the wrong approach. (the needle adjusts MID THROTTLE range mix)Sounds like you have a similar kit as me.
I am also having issues with mine.
Some advise for you to make starting easier.
Cut the plastic terminals off and solder the wires to make good connections and then insulate them.
I also had issues with the kill switch. I have since disabled this i suspect it was faulty.
Only problem i have now apx 3/4 throttle my engine starts 4stroking running rich.
I have adjusted the needle to the leanest position but same issue.
I now have ordered some smaller main jets to try out.
Pulling what little hair i have left to sort this issue out.
Will post my findings once i get the replacement parts.

If you are going to solder closed the main jet you need to drill it back out with machinist drill bits so you can make the jet a particular size, you can't just "leave a small hole" in the jet. At any rate, if you have new jets coming then I would try a smaller one and see how that works out. Also, make sure your air filter is clean and not oil soaked if you are running rich...Thanks for your reply.
It has an NT carb on it.
I tried adjusting the float but the result was the same.
I pushed those brass (tangs) i think thats what they are called a little lower.
I had the carb stripped yesterday and gave it a good clean out.
I tried the solder method on the main jet and left a small hole in it.
I didnt have a drill small enough but i used a fine piece of wire to push it through the solder whilst it was hot using a heat gun.
It improved a little but im not quite there yet.
I will have another go at it tonight when i get home from work and see if i have any success.
Aside from the above i will have to wait till the parts arrive and go from there.
Whats intresting when i first set it up initially it wasnt 4stroking after that it started doing it and now i am having difficulty trying to resolve the issue.
Hopefully my persistance pays off.
Regards
