use stock jets put in 96 in the primary and 150 in the secondary mains.

But firstly as said before check if the top of the carburettor is warped I can almost guarantee it will be use a straight edge to see or if its bad enough remove gasket and just place in on the carb and you will see the side lift up.

You can remove the plunger with a small flat screwdriver their will be 3 small cuts around the washer base of it you can pry it out.

once you fix these then i suggest putting in the stock jets but fixing the power valve never worked for me kept sticking half way.
