1) I'm going to follow the iboats #1 most recommended thing to do first: get the service manual. Question is, what exactly do I need? The "Service Manual Set?" Does anyone with experience know if manual 507508 is the right one for me to get? This is a 1985 Johnson 70hp WITHOUT VRO (not sure if ever had it or not).
2) In the meantime, where are the adjustments for the carbs on this engine? Are they all under the big baffle plate covering the three carbs? I believe my problem is excessive spark plug fouling (at anything other than idle). Friend of mine suggests replacing needle valves in the float bowls (I also get some fuel mix in the engine compartment). I want to try carb adjustment first then proceed with removing the carbs if necessary.
Thanks in advance for the help!
