decarbon question

[99seapro]

I have a 1999 Johnson Ocean Pro with oil injection and would like to try Dunk's decarb procedure but I have one concerns. Do I need to add oil to the gallon container of gas if useing a tank other than my in deck tank? Will the oil still flow as normal? Thanks for any replies.

It's a lot easier to inject the compressed form of SeaFoam (Deep Creep)using the schrader valve on the primer solenoid; you just need the $2.00 adapter hose #0763644: http://shop.evinrude.com/dyn_prod.php?p=763644

Re: decarbon question

thanks ezeke but do I inject it with the motor running and do I use the whole can?

Re: decarbon question

you start the motor either in the water or on muffs, you spray until the engine almost stalls, it will smoke alot, after it recovers, do it again, continue until it stops smoking, or you are out of seafoam. then run the heck out of it on the water, install new plugs, and another WOT round around the lake.

Why install new plugs if there is nothing worong with them to begin with?

You don't really need to, but there is a slight possibility that a chunk of carbon could foul one of the plugs. I've never changed them after a decarb and I would assume that if the decarb product was cleaning the top of the piston and head, then it would clean the plugs also.

Agreed, mine are always clean when I have the job finished.

If there is a lot of carbon, it may take several treatments. I like to see clean metal on top of the pistons when I'm finished.
