Need Help Honda B100

[pdaly28]

hello,I just bought a lowe 1236 with a Honda b100(b100-1001437)both bought in 1990 new.I finally got it started,and could not keep in running.Checked the plugs and adjustment on the carb.Adjustment screw was out 3 1/2 turns.I backed it down to 1 1/2 turns and got it running.The water discharge from the weep holes was minimal,but the discharge from the motor was pretty good.As soon as the motor got got warm(real warm)I couldn't keep it running again.So I suspect the impeller needs to be changed and maybe the fuel pump diaphragm.I can not find decent instructions on changing the impeller except on u tube(I am new deaf)so here I am again looking for some help!

You might try looking for a manual at boatinfo library here - http://boatinfo.no/lib/library.html#

I didn't see a B100, but there is a BF100. I don't know if they are the same.

You exact model number is BF100Z, could not find out exactly what years they were made though.

the only number was on the frame and I guess that is the frame number.It's a 1990 and was purchased at the same dealer at the same time the lowe 1236 was.I am the second owner.After putting in fresh fuel with sea foam,replacing the fuel supply line to the pump,it runs good but won't idle until it's warm.light spitting out of the weep hole and plenty of water getting thru the engine I am guessing the impeller is ok.It was replaced 2 years ago and the boat has had very light use(duck hunting 3-4 times a year)I have ordered a repair manuel as well.

after I receive the manuel i'll be adjusting the valves and checking the timing belt also
