Bad timer base symptoms?

[8up]

1986 140 h.p. V4 has weak stbd side spark and the intermentant hesitation.I swapped coils, new plugs, wires, new used power pack, carbs looked o.k. A friend of a friend says he's sure its the stator. Resistance check in spec Any thoughts please. Could it be the timer base.

Sure sounds like a pickup coil in the stator. Check the timer base resistance as per manual specs. I have only seen one bad timer base in my life. It was last month on a 3 cyl. 70.

Re: Bad timer base symptoms?

there should also be an output test in your manual. Ive never done that test so I couldnt help much. The timer base on my 70hp also went out.(failed the resistance test).........<br />try doing a search on this forum.........or wait for the pros to reply . they are probably out fishing for the holliday.................<br />I have found this to be a top notch forum.

Re: Bad timer base symptoms?

i am very interested in this topic. i suspect something may be wrong with my timing or stator. the engine will only start (when it does and will only run at high rpm before dying) when the bar under the fly wheel is only in one position or sweet spot????

Had same problem 120 hp 92 evinrude low voltage going to sparkplugs misfire high speed stator was bad i connected a voltmeter to starting battery that the engine charges 12 volts passed idle replaced stator had 14.2 volts passed idle runs great .found a small bulge top of stator hot spot in the windings. hope that helps

A little story. Almost 17 years ago this thread was started about weak spark on one side of his V4. Members made suggestions on the cause of the problem. The OP has not passed through the forum front door since 2016 and in all those intervening years he never once updated this thread.

Moral of this story; It's too late to help those who don't help themselves. So this thread is closed!
