" Joe, steve again the 79 evin

" Joe, steve again the 79 evinrude 85 hp, before i put this boat too use it sat in a garage well kept before it was shut down, but iv'e heard you or someone talk about running "de-carb" in the fuel to free sticky rings, now i havent done a compresion check but would it be a good idea too run some of this in mine for a tank or so of fuel?
the engine runs good but seems a like i can get a little bit more out of it.. thanks "
 
"Steve.... I wouldn't be p

"Steve.... I wouldn't be putting decarb in the fuel, It would be better to have the carb face plate off, then spray it into the carburetor throats as instructed... follow the instructions on the can.

Hard to say if it will help or not, but it will not damage the engine. Best to take a compression reading first and make a note of the readings per cylinder number. Then later take another reading which will give you a comparision that indicate that there was a improvement or not.

BTW... It wasn't me that spoke about the decarb solution, but it does work if the rings aren't stuck bad, and the carbon isn't excessive.
