Hi guys. I have been reading the forums for a couple weeks and has just been too lazy to register. i have learned so much already. well to the problem. i have a 1985 johnson 15hp. it will start on the first or second pull idle for days, then when i put it in drive it will bog down till i play with the choke and i can find a sweet spot for it to run at about 3/4 throttle. it will go full throttle perfectly then die after about 150 yard of WOT running. if anybody can help me out id really appreciate it. thanks in advance
