Peter,

Thanks for the advice on the ALDA.

I was wondering about the lack of smoke at full throttle. In fact usually, the only time I saw smoke was at night with someone behind me with their lights on. After backing out the ALDA set screw 1&1/2 turns, I did notice a puff of black smoke today in bright sunlight but only for a moment. 0-60 was unchanged at about 12-13 sec. Additionally; I think that the idle might have crept up a bit. Is this possible?

My next project is replacing either the timing chain, some of the guides or both. The car sounds like an intermittent rattletrap at idle. Sounds like the chain is slapping around inside its housing. Any advice on whether or not a backyard (barn) mechanic should tackle this task?

Thanks again…

Mav
