| I had been living in the mountains when leaded premium went off the market in Canada. The 700 kept on running fine with a couple less degrees of static timing.

Rather than re-tune the engine for lower altitude, I found enough aviation gas to get me back into the hills. Anyway, it made nasty noises just like you describe. I couldn't put any load on the engine until the aviation gas went in. It could be you have a not-so-great batch of fuel. But, if the engine is real sensitive to fuel quality then look for some reason that it could be running lean or running with too much spark advance. Lean-ness could come from a previous owner re-jetting the carbs to live in, say, Colorado. Too much advance could come from the static setting being wrong, or weak mechanical advance springs in the distributor would let it get too far advanced for the RPM of the engine. And, of course the points hafta be gapped right for the timing to be what you think you set it at. |
Thanks a lot for your post. As I reported back to the list, it DID get
much better with new super premium, although it was not as hot.
I 'll recheck the timing. Carbs are pretty good, and perhaps jetted a
little rich--I live a 4400'..
Thanks again!!
