To ChampionMan, thank you for helping me get closer to IDing my motor that has no model number plate remaining. It is believed to be a 1991 25/30HP Johnson short shaft tiller model. The issue I noticed was that while running WOT is cut back to 50-70% and I no longer had top end. After swapping out new ignition coils and test ran it again with no improvement. I completed a spark test (blue spark present 7/16 jump) and compression test (110 and 105 or 105 and 100.....age factoring in here). The research I found indicated to me I needed to look at the carbs. Well, with the motor not running, in gear, I noticed the butterfly in the carb throat only opening 1/4 of the way with the handle in WOT position. HMMMMMM!!!!!!! Upon further investigation I found a broken starter interlock cable bracket (325326). As I move the handle to WOT the nuetral start plunger (325332) does not allow the throttle cam to continue its natural progression thus keeping the carb butterfly nearly closed. So in short, I am looking to replace the cable bracket and once correctly aligned will see if the cam is back in action. Thanks again. Mark
