6 monthes ago, you got the bike to fire.... but it wouldn't run right at that time...
Now, after cleaning carbs somewhat, it fired again, and ran poorly....
I have to ask, did you remove that tank, dump that turpentine that used to be fuel, and dompletely flush and rinse that tank out.... or did you just try to start the bike after "adding" some gas to that tank....
Start over, and get that tank cleaned before anything else.
