    Medium line it is James....maybe next week I will order the stuff I need to really see if it will fire....by then I will know if it comes apart, gets cleaned up OK, no missing broken parts that I can't replace, and willing to take a chance that it fires up.

    John, does obsolete mean hard to find parts, illegal to use, or just an old system that is much less reliable and a pain for some reasons? I am not sure, but I think I did see a sticker on it somewhere with 72.xxx, or 75.xxx on it and I am guessing it is the older mhz if that was the std. back...

    Old K&B 7.5..~8702 mod, frzn crank and PTO done..now carb ??

    Thanks to the help from forum members, the crankshaft was freed up, cleaned and ready to go, same with PTO....Do I need to put grease into the bearings, and if so what kind ? Only wrecked 2 small parts, the threaded shaft that screws into the crankshaft to hold the cone/flywheel, and the small...

    Pictures are now attached >> OK, took the motor apart and was pleasantly surprised to find grease and oil in most spots...like drive shaft/lower unit, piston/cylinder. However, I can not get the crank to turn. I have it just in the crank housing, with carb off. Soaked in gas overnite, now have...

    The local hobby shop is a joke...all about planes only and a few plug and play boats, and nobody in there old enuff to even know what K&B is....so I will get stuff online I guess from Tower. The fuel line, pressure line from the muffler fitting, water circulation line, etc>>>do you think they...

    Great...thanks James. I also see where K&B outboards run in reverse, so the hookup to the battery for the starter is also backwards connections. Frank

    Old K&B 7.5...20+yrs sitting...genl help re lines/tubing

    James, for the fuel tank pressure, do I need to run a line from that nipple to the fuel tank or what ? The rest of what you told me makes sense & I get it...this still a bit of a mystery. I guess the pressure is created by exhaust stroke or something, but does it iternally cause the fuel line to...

    I have an OLD, square carb, K&B 7.5 from ~25 yrs ago...Can somebody tell me what the line/tube connections are that I see on the carb and motor? Looks like the connector on the cone of the carb itself must be for the line from the fuel tank since it goes direct to the carb (correct?)...but the...

    OK, most of the old engines seem to take the 1.5 V battery charger for the glow plug from what I can see on the various web pgs...can this old motor really take one of these newer type charger/driver for the glow plug? I would hate to burn the thing out on the first try. What should I expect to...
