This is my first post so bare with me. I purchased my bumble bee about 2 months ago non-running. The motor had given up on previous owner after he done a complete restoration of boat. My uncle got it to start about 3 days after i purchased so i was very excited. I took the boat out with my uncle to verify it was running and it ran great. Ran it about 800 to 1000 yards up river and back. Next morning me and the wife went out to enjoy our new boat and it was real hard to start but she fired up and was running excellent for about 500 yards and then it was like i was letting out on throttle but i wasn't. We brought it back home and i started investigating my problem. I had been reading iboat forums for quite some time already so here i went. I have read what seems like 2 long novels of problems similar to mine but none seemed quite the same. I did use those to troubleshoot mine. Here's a list of some things i've done: checked compression 95 lbs all four cylinders', rebuilt carbs, done link and sync, changed starter"other one was getting weak and ended up dying", finally done a spark check and suprisingly to me it couldn't jump 7/16ths. i replaced powerpack with genuine johnson pack and still nothing. it would jump about 1/8th and thats it. then noticed a bad place in wire on rectifier so unhooked it and wallah.. spark jumped 7/16ths no problem and motor actually started on three cylinders.. now im exstatic.. so i take it to the river this morning and planned on it just running like a champ but nope. same problem.. starts up super easy now, idles awesome, give it gas and it just feels like it goes to half throttle and stops. stick keeps going, throttle advaces on carbs, timing advances as it should, it just is super sluggish. the boat will get on plane and run but it feels like its at a good cruising speed even though it is wide open and should be burning the wind. i have eased in the throttle and it doesn't help. pump the bulb and no change. hit the choke and it tries to die. can someone please help me. as stated in title it is a 1977 JOHNSON JAVELIN 85 H.P. oh one more thing, i checked compression again and it is now 105 on three cylinders and between 100 and 105 on the other one. Thanks; JUSTIN
