hello, i have a set of carbs from a 1997 yamaha waverunner that im having an issue getting clean.  alot of the smaller ports and openings are clogged with old dried gas i believe, it sat 10 years.  i purchased 2 gallons of your 0996 carb cleaner chem dip, but its not working as many others say it doesnt work like the old stuff.  do you still sell the old strong formula?  if so can you tell me where/how so i can get some?  im not having any success with 0996 formula and need stronger.
