Offering the following as explanation/clarification: not flaming, demeaning, trolling, disrespecting or angrily ranting.What you need to do is get out your wallet & purchase one of my DS11's. .... In the meantime check out my listings in the small six for sale section here on the forum. Bill wsa111
The distributors I bought are for the 75 Maverick with the 250 I6.Are you positive that your's isn't adjustable? Is this a DS2 distributor? The cardone reman spec'd for a 1978 Fairmont 3.3 I bought for my 250 was. Try different allen wrench sizes, I think I've read 3/32 but I'm pretty sure mine was different size than that. You could also get one to the auto parts store and check it before you pay for it and take it home. STANDARD MOTOR PRODUCTS VC473
Is this what you want?Show a photo of the chamber from the bottom side.
It's basically a stock 250 - I asked the rebuilder to make it stock - nothing fancy.I will remove one of my adjustables off one of my DS11's for sale & put it on the Sun tester & give you the total advance it has.
The vacuum part tops out at 9" of vacuum.
I don't know the specs on your engine nor the the total centrifugal advance & what rpm it tops out.
What initial are you running???
John, when you are ready get in touch with me cause you are leaving a lot of performance on the table. BillIt's basically a stock 250 - I asked the rebuilder to make it stock - nothing fancy.
I don't remember what I set the initial timing to but I think (emphasis on "think") that it's around 6° btdc. Without looking I'm pretty sure that's what the shop manual said to use and I didn't want to get too aggressive with it until after I'd broken it in for 1000 miles or so.
I don't know the total centrifugal advance - I have not measured it yet. When I get to experimenting with that I am thinking that I'll want no more than 25° total, all in around 2500 RPM.
I've gotten sidetracked into fabricating air conditioning compressor mounts and hoses and getting all of that stuff hooked up and charged so I won't be working on the distributor or timing for a while yet. Please don't go to any extra trouble for me - although I appreciate the effort I'm not sure what I'd do with the information. Hope you understand.
Many thanks for your help.
Best, John
