  • rave valve readings?

    I cleaned the raves yesterday on 97 challenger with 800's and noted that the Mag rave had more oily carbon deposits than the pto rave. Should I assume that the Mag carb is alittle rich and the pto carb alittle lean and adjust low jets accordingly? Hig jets are set at zero.

    You cannot make any adjustment from RAVE deposits. Read the plug reading article in the tech section.

      My engine is a year old SBT engine. When I set it up, I did so with plug readings, as per your tech section. I converted to premix when I installed the engine, rebuilt carbs as well. Boat has run terrific with the new engine. I guess I'm still alittle nervous and jerky about running lean on the pto cylinder. Thanks...SBT is the best!
