timing with a 009 distributor

fonz15 · Posted: Wed Nov 04, 2009 2:44 pm Post subject: timing with a 009 distributor

so my stock distributor messed up after 39 years so i got a 009. But my timing is still off. I heard that its hard to get the timing right and i should get a degree pulley or a 009 with a vacuum advance and that either of those should fix the problem. I have a 70 beetle std. stock 1600 engine. thanks for the help guys but what should i do? can i time it right with out the other stuff? will that timing stick? advice??

9 Degrees - and -009's don't work well with the 34 pict carb

In my opinion, you would be better off getting the stock distributor fixed, or getting a replacement of your stock distributor. If you MUST use a 009, get a degreed pulley or a timing light with an advance dial so you can adjust the gun to read advance with the stock pulley, then set it for 32 degrees max advance with engine rpm at 3000+.

You time a OO9 to 30 degrees BTDC @ 3500rpm... you should not time it at idle.

They don't make a OO9 with vacuum advance. (and don't say the 0 231 137 009 that's not what he's asking)

Here is how to mark a stock pulley....from www.type2.com

Timing the Bosch OO9
by Ken Hooper

The thing about timing is that what matters most is what happens at cruising speed, maximum advance--that's where you can burn up an engine quickly if your timing is too far advanced.

But: The Bosch 009 does not have a predictable advance curve--the German ones are different from the Brazilian ones and the worn ones are different from the new ones and on it goes. The natural result of this is that just because you've timed the 009 properly at idle does not mean you have any way of knowing what's going on at highway speeds.

So while the stock vacuum advance distributors can safely be timed at idle (or even timed statically per Muir, although this is never optimal), the 009 has GOT to be timed to about 30 degrees TOTAL ADVANCE with a timing light. Which means you have to rev it up until the distributor stops advancing before you can dial it in.

It takes three hands and if the process isn't painful, you aren't doing it right. =^ ) It's okay to time it statically at around zero degrees in order to get the engine started, but you have to finish the process dynamically by making lotsa noise.

It is very easy to find 30 degrees without a degree wheel as long as you know where top dead center is. From TDC, measure an inch and three quarters (1 3/4") to the right around the diameter of a stock pulley. That's about 28 degrees, go a tinch further and mark it with fingernail polish or something.

If you don't know where TDC is, then you have to pull the #1 spark plug and push the eraser end of a pencil in the hole and rotate the engine and feel the piston until you figure it out.

A basic timing gun is ~$20, get one and carry it with you, it's an irreplacable tool.

when you talk about the degreed pully you are talking about the big one with all the little marks on it right? Don't those run like $30 or so? I'd just get one

Oh, come on!

Isn't a steel ruler on a Berg pulley is a least a little bad-ass?
