Hi Matt: So far, you're still describing what appear to be normal conditions for the parts you've got. A few years ago I was able to find replacement advance springs from AR Ricambi, but be forewarned, the person you speak with on the phone likely won't have a clue, so search their website and just give them a part number. And FWIW, a '72-'74 Spica Spider should run a lot better than just about any other Spider you've driven, and with everything in proper tune it should run great at all rpm's and throttle positions. It worth getting things right. http://www.arricambi.com/ Regards, Dean At 11:53 PM 6/17/2004, you wrote:
Thanks for the replies I have a PLEX 10 system in the car, which was used in the 80-81 spiders. True, I don't truly know the springs are dead, but there are two different kinds of springs in the advance mechanism (different weigths and coil counts), and one of them is overstretched so it doesn't even engage in the first 1/4" of travel of the weight. The rest of the SPICA is still in
place.
Oh well. The car still runs pretty well when it's wide open... :) - MattFrom: "Dean W.

Date: Wed, 16 Jun 2004 22:19:23 -0400 Hi Matt: I'm not sure what criteria you're using to determine the condition of the advance springs, but a fair amount of free play is built into their mechanism. The only proper way to check your timing, and advance/retard with rpm changes, is with a timing light (preferably an "advance" timing light with a dial indicator or digital display). Tried that? Assuming that you have, there are other considerations, and given the choice between having the timing set properly at 5000 rpm's or idle. most of us would choose the former, and that's not necessarily something that needs intervention. Further, if the distributor is in fact from an '80 Spica Spider, you'd be better off with the original distributor, with regards to having an advance curve that suits the '73 Spica engine. Finally, I'm sure most of us are unsure what distributor you're speaking about, since all the Spica cars used Marelli distributors, although among the later cars, some had dual sets of points and some were breakerless. Do you have a model number? Does your '73 have its Spica system still in place?_________________________________________________________________ MSN 9 Dial-up Internet Access fights spam and pop-ups - now 3 months FREE! http://join.msn.click-url.com/go/onm00200361ave/direct/01/
