I'm a first time boat owner so bear with me for a while.I have several questions concerning my motor.First I have been unable to find out the year of it .the model # is TRL-10R , also what is the point and plug gap for this model. I had trouble finding the type C lower unit lube and was wondering if there is something to substitute for type C ?<br /> Now for my problem. I have a miss on # 1 cylinder and can't seem to get it out. The plug is wet with fuel but if I remove the plug wire I have a good blue spark. I've tried switching plugs and the problem always is on #1 cylinder . <br />Compression is 110 lbs on all three cylinders. <br /> I guess I should have mentioned first thing that my motor is a 3 cylinder Johnson 55 H.P.<br /> I have reset points to .010 ,they were .020,and gapped plugs to .035,checked rotor and plug wires and found nothing wrong.The miss stays with the motor at all r.p.m. levels. If I pull #1 plug wire off the motor smooths out ,replace wire miss is back. On the side of the motor ,near the throttle linkage there is a rubber disc about 1-1 1/2" in diameter with 2 brass disc behind it . What is this and what does it do?<br /> Any and all help will be greatly appreciated
