Greetings All-I recently replaced my cam chain, rollers and tensioner on my 71 CB350 and now I'm having all kinds of trouble setting the timing. Nothing is aligning right. I have great spark at plugs and points. The valves slackened as they should for adjustment at the LT and T marks so they are set right. I have brand new points and plugs in. All wiring connections are good. The iginition switch is ON. I'm getting fuel flow. What I'm not getting is the engine to fire up. It just pops and spits.
I've tried the test light routine and moved the backing plate all over the place with no good results. I've read all kinds of ways this is supposed work. Some say the light should come on at LF other say is should go off at that point.
Per the manual, the timing is correct if the left point begins to open at the LF mark on the compression stroke. I have just the opposite. The right point opens. What I dread is when I set the sprocket with the L mark straight up at LT on the rotor, I wasn't truly on the compression stroke. I'm assuming that puts the cam lobes in the wrong position for timing. Is this the case?
I would greatly appreciate hearing from someone who really has experience with this. I have a lot of time, and money, tied up in this so I'm not about to walk away from it. If I have to pull the engine and reset the cam sprocket I'll do that, or whatever it takes, to get this right. So any bad news is pretty much expected.
If you have just got it 180 degrees out of phase, all you need to do is switch the blue and yellow leads from the coils to the points and bob's your uncle. Of course, now your timing marks will be reversed but that beats pulling the engine, eh?
