Hi all,
Thought I'd write back with some new info on my "loud timing chain". First,
thanks for all the feedback and potential causes of this noise!
Here's the solution: Today I was tuning the engine, for the first time since
firing it up. I had set the timing to exact TDC (well, real close!) and was
having a hard time adjusting the carbs. So out came the timing light and
shop manual to find the correct timing of 4 degrees BTDC. I set the timing,
and voila! No more noise! I adjusted the carbs - real easy when the timing
is set correctly - closed the hood and whet tearing down the road in a
wonderful throaty growl of dual pipe stainless exhaust and no clatter!
No idea if this makes sense, but thought I'd share my experience.
