Hello all I have been trying to get an injector cup out of an LB7 for quite some time with no luck. I have marked the cup and the head to verify that it is moving by installing my kent moore j45910 cup puller and moving it. The damn thing will not come out though. I dont have the tube with the j45910 is it a neccessity? If anyone would like to sell me a Bullfrog Johnson setup I would buy it in a second. I have searched hi and low around here to come up with the dimensions of his setup and no supplier around here can I find anything close. Thanks in advance, Randy.
