new k&b .67 inboard that sticks when trying to turn over

Postby shawnxk » Sun Nov 07, 2010 2:32 pm

I have a new k&b .67 inboard that is very hard to turn over. It is so tight I can not turn it by hand. I managed to get it started twice. I am using a sullivan hi torque starter and a brand new battery.

What you are experiencing is completely normal. The ABC piston/sleeve has a slight taper as the piston reaches the top of the stroke. One way to help starting is to loosen the glow plug slightly when turning over the motor. I know that McDaniel used to sell a torque Ni-starter that acted both as a glow plug driver but was also a glow plug wrench. You'd loosen the plug for starting and then once running tighten with the torque starter wrench.

K&B boat engines were notorious for this.
