 |
|
I'm putting a Bosch 019 dist. in my 1600 dp single carb motor for my 67 westy. Anyone reccommend a timing setting for this dist? I think I'm running 7degs BTDC with the stock vacuum job. Thx

Set it 28*-32* BTDC at 3000rpm.
You should never static time a mechanical distirbutor.

Glen, I have a stock vw pulley w/ no major timing marks, any suggestions where 28-33 degs BTDC would be? Maybe one of the press spokes on the pulley face?

46mm from the TDC mark is 30 degrees.

oc, thx for the info-I assume that is 46mm along the top plane (edge) of the pulley?

Correct. Once you measure the distance just mark it with a line of paint.

Why? I've never had a problem with static timing mechanical, vacuum only, and SVDA distributors. I occasionally hook up the timing light to see if they are advancing properly to 30 degrees, but that is a diagnostic, not a setting method.

Because they vary in maximum advance (especially cheap 009s), and your advance at 3000 RPM is a hell of a lot more important than at 0 RPM.
Sounds like you've had good luck with distributors. |

Not so much good luck as I've checked them at both ends of their advance curve. The only one I've had that didn't advance correctly is the worn-out DVDA that came in my bus. |

Print this degree wheel and use it to put a paint mark on the pulley.

For what it's worth, with point-less pertronix, compufire, etc. systems, I find static timing to be useless. Besides, w/ the "quality control" of 009's I'd rather some comfort of knowing the total advance using a strobe. Yet another one of the Muir'isms that I strongly disagree with.
Having said that, I'm quite happy w/ my 009...so far.

By luck, I meant that the ones you got had the correct advance. As 009s vary all over the map, would you feel right telling someone to just time theirs statically? I sure wouldn't. |

BTW... the 28*-32* needs to be "dialed in" due to the type of fuel, combustion chamber shape and compression. You want to have the most advance with out the engine "pinging". Start with 30 and if it pings, back down to 28. If it doesn't try 32. If you use Premium gas, then 32 will most likely be fine.

I generally advise people to put the 009s on the shelf and use a better distributor!
I would be very leery of any distributor that varied from a reasonable advance curve. If it doesn't advance enough and you set 30 degrees at 3000 RPM you'll end up too far BTDC at idle. That isn't good either. |

| My 019 advances to about 3200 rpms. Should I set timing at maximum advance. Or as most things I see about setting at 3000 rpm |

Max advance, that's why I say to do it @ 3500rpm.

just so I am sure, you always set the timing at full advance and it doesnt matter what the timing at idle ends up being.
mine idles @900 rpms and is @ 10 degrees

You're fine.
019 only has 17* so at 28* total advance you'll have 11* initial.
