Alright... I didn't even know which ped you were talking about in the first place.. so I gave general info.
(some of which is not right for all models)
That is one of those Encarwi carbs?
One important thing that is very easy to miss.
When you are putting that float back in... sit there and get very comfortable with the fact that you have centered that needle in its little hole in the bottom of the float bowl.
If you just drop it in... or even fairly carefully slide it in... the needle can still miss the hole.. because of a bad design IMO of that little boss with the hole in it in the bottom of the bowl.
My advice is to put it in a little crooked on purpose (the needle will miss the hole and slide down the side of the boss).... then slowly pull it back out while applying slight sideways pressure to "feel" it slide up the side of the boss... If you use your eyes and fingers carefully you can make sure it finds the hole... since you cannot see the needle going in... you have to be very careful to correctly locate the hole.
A bad design... (because it is verrrry easy to miss the hole) and only a smart careful person will get it right.
I can't tell you what else might be wrong with it... I am not real familiar with that carb.
I hope that is it.
