I have been having problems while running wot, sometimes I'll get 4500 rpms sometimes 5000. when I can only get 4500 sometimes it jumps to 5000 for a couple of seconds and then back to 4500 with out me touching the throttle. any ideas?
I had the exact same problem with my 88 Spl. When you have it out and it is acting up, take a screw driver and tap on the power pack and see if the engine reacts every time you tap it. I did this to mine while it was under a load and every time I tapped the pack the engine would respond. I changed the power pack and was out fishing in no time.
