A good mechanic I know told me to warm up my older 4 mixes rev them up and spray water directly into the carb. He says do this for about 30 seconds on and off keeping the unit running and it will decarbonizing the engine. True?

I do it on any engine I have, but you have to change the plug after. And use a spray bottle on mist if you put to much water in it will hydro lock. If you do it on a 4 cycle engine change the oil and filter right after too.

Think I'll stick with SeaFoam Deep Creep.

add it to your gas or spray it into the carb or stick a vacuum line into it.

Is Seafoam Deep Creep more effective than regular Seafoam? I have both. Thanks.

I don't know if there is a difference in liquid vs the Creep.....I just trust them when they say spray it into the carb a few times when unit are running bad. Always seems to make things better but.....hard to measure results unless you take the head off and look inside. I definitely know it will not clean up the ports on an Echo when they are clogged/

The Stihl product works. It's been tested by Stihl and it does no damage. It sometimes takes 2 procedures to work. Especially if you use conventional oil. I work at a Stihl dealership, and use the product often.

Should a 2 cycle be de-carbonized as well or only 4 strokes?

It is an old mechanics trick, I used to have a boss at the one garage I worked at. he sold used cars... talk about balls, he would hold the throttle wide open floating the valves and either spray water in or sometimes he used transmission fluid. both worked but the trans fluid was best for the cloud that would take over the area... I would say use the good stuff that is proven we do.
