Hey guys I've got an extremely clean and well maintained Johnson 150 that has suddenly started running sluggish and bogging at midrange. Starts up fine, idless fine, and even runs pretty decent wide open. But upon acceleration and during the entire mid-range is very sluggish and boggy. Here is a list of everything I've done and tried so far:
-Compression test 100 psi +/- 5 on all 6
-New correct and properly gapped plugs QL78YC @ .030
-Swapped out all electrical components with know working ones :stator, power pack, optical sensor, couls and voltage regulator
-Tested with 6 gallon tank with new hose, primer bulb and fresh fuel to rule out fuel/delivery issue
This one has really got me stumped. Any advice or what to try next would be greatly appreciated!
