Is the Johnson tune up stuff in the aeresol can a decarbing substance somewhat like Seafoam? If it is, does it also provide other benefits to the engine?<br />Stalker
A decarb is about all you're gonna get, which, ain't no bad thing. Your TCW-3 pretty well supplies everything else it'll need. <br /><br />c/6<br />Hooty
If you are speaking of the OMC engine tuner,it is indeed a decarb product.It works great and is easy to use.If your engine is equipped with a schrader valve on the primer solenoid under the engine cover ,it is a snap to inject.It puts the "go juice" right where you want it.Into the intake chamber passed the carbs.Just follow the instructions on the can.
