After 40 plus years of using carburetor dip I’m amazed how good this works.I have cleaned hundreds of carburetors and back in the day carb dip with reciprocating basket was only way to go, BUT now days carb dip is weak at best and until I found this I replaced a lot of carbs because just couldn’t get them clean inside of tiny passages, but this with a little cleaning solution I have had great results.If you need a cleaner get a heated one like this one, works great!!Not a paid or reimbursed review.
