I need to decarb my 70 go force. What product do y’all suggest and what procedure. I have done it plenty on four strokes but never on a 2 stroke will spraying directly in carb intake lean it out to much and cause wear damage?

Yes I think I can.
Decarb, if it's in a spray can then spraying direct into the carbs won't hurt a thing.
OMC, Mercury, Yam all make/use a product, I think all use the same product just a different name. Power Tune, Engine Tuner and the Yam product(not sure of the name)
I get the motor hot and then as it's running at a little over fast idle, I start spraying into the carbs.
Spray heavy almost make the motor die.
Then shut it off, remove the plugs, tilt motor up and spray into all the holes, turning motor over slowly so it coats everything.
Then leave it up and let set for 48hrs.
Try not to get the spray on anything plastic(might melt it???)
Then after 48 I start it making sure the plugs don't foul, then run it.
Then maybe new plugs?
