My engine is an 86 Johnson 90 horse-- Model Number: J90MLCDC 1986.

It starts fine, but when I push the throttle forward I don't get full power. It bogs down. --So the throttle is full but it doesn't even have enough power to get on plane. Sometimes it goes and then cuts back. I have changed gas and checked plugs. It does not stall; it just can't get out of the hole.

I saw a post about a timing wheel/heat soak. Is this my problem?
