BK probably dumps the whole bottle in a gallon of gas. I use it everytime I get gas for my boat, just a capful, plus a shot of marine stabil to keep it running smooth. I suppose if you never used it and you had a lot of carbon build up you would want to use it a little heavier and it would smoke alot as it was burning. Take a look at your piston through the plug hole let us know how bad the carrbon buildup is.
I use it.Its been around for a long time & all the ol timers swear by it.Thats good enough for me.Its suppose to be the best thing going to help burn off any water that gets in your fuel & helps keep the carbon down too.I add just alittle bit at each fill up(whatever it calls for)& then I put a full can in,last fill up of the season.I ran that down till almost empty,so I should be ready for this year.Its not cheap,a gallon will run ya close to $70.Advanced auto has the small cans on sale all the time.Gman's using some shit you can only buy at home depot,maybe he will chime in.
