    How do others manage to access the #4 plug on your engines without standing on your head and twisting your arm and hand in silly positions? Would taking the upper cowling seal off or loosening the mid section in front help? The hardest part is getting the plug back in straight and not cross threaded!!!

    I use a swivel socket and have never had any issues getting to that one. Just take your time.

    Like mentioned getting it back in is the big issue! My hands don't contort enough to get there easily. I too use swivel to tighten once started. Thanks.

    Piece of fuel line is very helpful (or better yet, clear vinyl tubing) when reinstalling plug. Helps to prevent cross-threading.

    You could remove the port side lower cowling for better access if you wanted.

    Thanks Don for the tube suggestion, I had not thought of that one. I think I'll try that next time before going to the trouble of removing the cowling.
