Title: MSD distributor timing help Post by: reijo5 on September 27, 2009, 18:52:41 pm Ok i was gonna set my msd distributor to 30 deg @ 3000 rpm + like a 009 , but it has the heavy silver spring s in so full advance is not going to be in till over 5000 rpm also i checked to see which adv stop was in , expecting to see the blue one as
i have a bag with the other springs /stops in and the blue was nt in the bag , but it was not blue just lightly rusted :D ( lovin the uk climate) but it looked only slightly smaller than the black stopand larger than the silver so maybe it used to be blue ? if i remove and measure what size should it be? so what should it be set at ? its a 2276 130 cam 48 idas timms stage 2 heads , and also are the big silver springs and blue advance stop right for this set up ? this is how i bought it. Thanks for any help jamie Title: Re: MSD distributor timing help Post by: bang on September 27, 2009, 19:53:58 pm i am running with one light silver spring and a blue spring and then i use the biggest black washer for adwance stop..

Title: Re: MSD distributor timing help Post by: Rasser on September 27, 2009, 20:09:52 pm You will probably want it to be fully advanced at somewhere between 2600-3000rpm, and the advance should START roughly 50-100rpms ABOVE your idlespeed ( a lot of people have their advance and idle speed mixed together, and this will result in bad idle). A good starting point would be a 20degree total advance (10-30 degrees - or similar). You will have to fine tune it to your engine, but at least this will get you started.
Luckily a spring change is quickly done on a msd distributor, so you should have it set up fairly quick. Avoid detonation - Good luck ;) Title: Re: MSD distributor timing help Post by: bang on September 27, 2009, 20:31:30 pm on msd homepage you can see what the springs does and the adwance stop. i set mine up so it starts at 1500 rpm and stops at 2800 rpm.
and it it set on 28 degrees at full adwavce. my engine is a 2779ccm with 12,6: 1 in compresion. Title: Re: MSD distributor timing help Post by: reijo5 on September 27, 2009, 20:42:05 pm Thanks rasser & bang you have been a great help guys.
