How to recurve a 009?

Hi,

how to recurve a 009?
i like to have 14-17 at idle and 32 total, in at 2000rpm.

You need to:

add/remove material (ie. weight) from the weights
increase/decrease spring tension
reshape the the cam area the weights ride on to change the curve
bend the tabs that control the amount of movement of the weight

You need the knowledge to know how much to do and a distributor tester to tell you what the results are.

















Or got can get a Mallory that has different springs and and stops to control total advance.

Hello Glenn,

what about a srew or anything that only limit the distrbutor  advance curve? A 009 has a total advance about 20-24 and is all in at 2500rpm , if i'm right?!?
By limiting the total advance curve to 15, so you can start at idle with 17 and end with a total 32?!? .....and it must be all in before 2500rpm

My 009 is setup this way almost exactly. Take your points plate off the 009, and bend in the stops for the weights. It will, as Glenn said, necessitate a distributor machine OR some old-fashioned trial-and-error. I made no other changes to my distributor, and it works well.

Or got can get a Mallory that has different springs and and stops to control total advance.

That's my ultimate goal. I have the Mallory, I just need the funds to buy the tune-up parts and tuning kit. And I'm really looking forward to putting it into service.

Hi Mike, i will do it that way!
Trial and error is no problem

Thanx

to reduce the amount of advance all I do is get some small heatshrink tubing, cut a piece to go over the advance stop,heat it on,and then check it fitted back in the car to see what it did to reduce the advance,if it needs more then add another layer,nice and simple and easily put back to stock again

cheers richie

Another option is to take a Bosch 019 mechanical and remove one of the springs.

The 019 has 17*, so 32-17 give a initial of 15*. Normally the advance is all in at 3200, but if you remove one springs it will come in much quicker. The 019 has a cast iron body with bronze/silicone bushings and is very stable.

But a 019 will cost you money and if you already have the 009 then give it a shot.

Shit, that IS clever! I like the idea.

The 019 has 17*, so 32-17 give a initial of 15*

Another good tip. I hadn't realized the 019 has fewer degrees of advance.

Thank you all!!!

I will do it like Richie said.
