Hey guys I need help ,does anyone know what's the timing on a 71 bug w a 009 distributor w/o vacuum advance ? I read an article that it said it has to be 5°ATDC but on an other article said it has to be on 10°BTDC can anyone help.thanks in advance |

Neither.
If you have to use a 009 at least time so it will work as well as it can. After you figure where TDC is on this thing (keeping in mind that the notch on the pulley from the factory was at 5º ATDC) time it so all of the centrifical advance is all in and make that point to be 30º +/- 2º. That should happen by about 300-3500 RPMS.
Let it loaf back to idle and note where that intial timing falls but don't change it.
A better distributor would be a plus to have. |

Use this thread to identify which pulley is on your engine. 5* ATDC is for a DVDA distributor with two different vacuum lines going to it.
Follow Randy's advice on how to time the 009. I also agree that the 009 isn't the most ideal distributor, especially if you're running a 34-3 distributor. _________________ Contact me at [email protected]

See the two responses above. I agree 100%, and I do run a German 009 on my 1971.
The timing needs to be about 30 BTDC at about 3500 rpm, regardless of the distributor or carburetor. Then - like posted - the timing at idle or static timing falls where it does, and it does make sense to make note of that too.
Under those conditions, my German 009 static times to 7.5 BTDC, but that was manufactured 40 years ago; since then, South America or China is where they are made, and their quality is not the same.... _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each.

For centrifugal applications, I'm partial to the Bosch 010 old cast iron distributor.
They show up occationally here on thesamba, less frequently on ebay.
Or you can buy a completely rebuilt one from Glenn - http://www.thesamba.com/vw/classifieds/detail.php?id=53482 _________________ 70 Beetle, 70 Beetle, 71 Beetle, 71 Super, 73 Super, 74 Beetle, 2000 Vintage Speedster, 2020 Jeep Renegade, 71 Squareback |

Other options include a Bosch 019 and (assuming you have the factory correct carb on this thing) the correct DVDA or SVDA distributor.
Any of those would be better than the 009 you currently have. |

Randy is correct with timing the 009. At 3500 RPMs you should be a max advance and you will set your timing around 30°BTDC, I say around as I have seen some run better at 28 and some run better at 32. |

I have another distributor w vacuum advance but I couldn't set it right, here what :I did I set the pulley at TDC the rotor was pointing to sparkplug wire #1. When I set the vacuum advance distributor the rotor was pointing to sparkplug wire #2 , i change the wires Fire order and couldn't get it run . I know u probably think I'm stupid but don't know much about engines I'm just trying to learn.and the carburator its a solex 34 pic 3 |

Some (possibly all??) of the 009 distributors have the distributor cap rotated 90 degrees off from the stock distributor. You just have to reposition the spark plug wires on the cap, #1 wire goes to whatever terminal the rotor is pointing to at TDC on cylinder #1. The firing order does not change. |

Have you picked up any VW workshop repair books yet? Read any of the detailed threads about this very topic? You have to do that in addition to asking and hoping for replies. TheSamba is its own google of all you wanted to know about your distributor, carb, timing, etc --if you search for it, someone's probably answered it already! _________________ Eventually, "we are what we pretend to be.’”

I always put a new distributor in with the engine at TDC on the compression stroke for number 1. I then install the distributor and see where the rotor is pointing. I then put #1 spark plug wire where the rotor is pointing. Then move the rest of the spark plugs wires correctly on the cap. 1-4-3-2 is the firing order. As mentioned, different distributors point at different positions.
It's great that you're trying to learn! We've all been there. A good book to help you get up to speed quicker is How to keep your VW alive by John Muir. You can pick them up used for next to nothing.
What's the distributor numbers on the vacuum distributor you were trying to make work? _________________ Contact me at [email protected]

This is the distributor w vacuum advance , already set it in the bug, just needs to get the right timing . |

Wow. If it were me. I'd rotate that dist 90* away from the intake manifold. Then re-index the spark plug wires. The way you have it set now if you move it far enough clockwise it will hit the intake manifold limiting your ability to properly adjust your timing.
Good Luck. _________________ I have learned over the years.

Agree with above. ^^^
Then, ditch that "Bruck", Chinese POS and get a rebuilt Bosch distributor. _________________ Contact me at [email protected]

I think your 205N is vacuum only advance like the 205T I run. It wants to see vacuum signal from right below the venturi on the carb. Timing should be set at 0 degrees with vacuum source disconnected and plugged.

Is your engine running w/ the 009 installed? If not, then you may not have the correct position for #1 spark plug wire on the distributor. I never trust the common locations or any markings on the distributor until I have confirmed definitely WHERE the #1 plug wire position SHOULD BE on the distributor.
This is how you find the #1 plug wire position on the distributor.... without first looking at the distributor rotor:
Rotate the crank pulley until the TDC mark (or one of the timing marks) is lined up with the case split.
Remove the #3 & #4 valve cover (left side of the engine).
Rock the crank pulley back and forth a few inches and watch the #3 valves/rocker arms for movement. If the engine is at #1 TDC at the end of the compression stroke, #3 cylinder will be at the end of the exhaust stroke. The #3 exhaust will be closing and the #3 intake will be opening; so the rocker arms will be moving the valves.
If the #3 valves are NOT moving, rotate the crank pulley 360-deg and check again. Once you see that the #3 valves are moving while the TDC mark is near the case split, you know the cam and crank are in position for #1 TDC at the end of the compression stroke.
Remove the distributor cap. Look where the rotor tip is located. The #1 spark plug wire MUST BE located above the tip. Even if this is in the wrong location you know the engine is expecting the spark to go to the #1 cylinder so you MUST install the #1 plug wire over the tip of the rotor.
Look along the rim of the distributor for a small nick/notch. This is the mark to remind you where the #1 plug wire belongs. Now that you know the rotor tip is pointing to the #1 position, loosen the clamp bolt and rotate the body of the distributor until the mark lines up with the rotor tip. Now you can trust this mark is the reference for #1 plug wire.
If you rotated the distributor you should static time the ignition to around 5-7BTDC. This is good enough to get it started.
Install the cap and insert the #1 plug wire into the post that is closest to the rotor tip.
Install the remaining wires in the clockwise firing order of 1-4-3-2. Some will go CCW and use 1-2-3-4. It works out the same.
If you are not certain which cylinder are which, look at the engine tin in front of the spark plug holes. The cylinder numbers are embossed into the tins.
One point to take away from this. If you remove the distributor while it is pointing to #1 plug wire and install another. Once that new distributor is fully seated, the rotor MUST BE pointing to the #1 plug wire position, even if the rotor is pointing to a different position than the old distributor. Because you haven't rotated the crank, the engine cam/crank are still positioned and expecting the spark to be delivered to the #1 spark plug. The rotor MUST be pointing to the position for #1 plug wire. _________________ AshMan40

I think that Petronix would be a great door stop. It's just another Chinese copy that many folks complain about on this site.
