All I can say is would you rather drive a Yugo or a 69 ZL1 Camaro. If you like Yugo's then send your carb to one of those so called carb shops. If you want the best then send it to Dr. Eric Jackson.
Heck I had a heart attack and was in the hospital for a week and felt like I had been run over by a Mac truck. But when I got home and got the package open I felt like I had died and went to heaven. He's the best!!
