|
|
I'm finally switching over to an SVDA and trying to static time it but the new one has no notch indicating cylinder #1. I thought that other than the vacuum advance, it's essentially the same as a 009, which I'm familiar with. I can't get it to start, am I doing something wrong? _________________ '74 Standard Bug |

The notch on a 009 is generally 90° off from a stock distributor.
In the end, it doesn't really matter. Set the engine at TDC of the compression stroke on cylinder #1. Wherever the rotor is pointing, that is cylinder #1. Then, follow the firing order for the rest of the plug wires. _________________ *ASE Recertified Master Automotive Tech*

Thanks. Maybe I'm on the wrong stroke or I got the plug wires mixed up...wouldn't be the first time I'll keep trying. _________________ '74 Standard Bug |

In general, if the distributor gear is in the proper position, and the distributor drive dog is on correctly, it will look like this:

THIS!
I always tell people to forget about the notch. Just make sure your on TDC #1 and see where the rotor is pointing. That's #1. Many times the distributor drive gear was not installed in the proper place and it changes the location of the terminals.
You can go and relocate the distributor drive gear, but it's not necessary. |

Huh? I thought the firing order was 1-2-4-3? Your pic looks like 1-4-3-2..? _________________ '74 Standard Bug |

It is indeed 1-4-3-2. It should be cast into the bottom of your generator stand, assuming it’s stock. _________________ *ASE Recertified Master Automotive Tech*

I had to stop for the day but it appears I know what I did wrong. For some reason I was incorrect about the firing order. I'll take another crack at it this weekend but I'd bet that's what was wrong. Thanks for everyone's help! _________________ '74 Standard Bug |

Agree with the above.
Rotate the crank while watching the #1 cylinder rocker arms. When both #1 valves are closed AND the crank pulley shows TDC... you are at the end of the compression stroke for #1 cylinder. That cylinder is now expecting a spark. The distributor needs to be set up to deliver that spark to the #1 spark plug wire.
The other thing to consider with an SVDA/DVDA distributor is placement of the vacuum canister. The above pic shows the stock position for the vacuum canister. If your canister is somewhere else, now is the time to remove the distributor (if needed) and rotate the distributor body to get the canister in the correct (or close to correct position). Placing it as shown above will give you the best range of motion for adjusting the timing.
Next, set your point gap and static time the distributor. Add a paint mark or notch into the rim of the distributor where the rotor is pointing. You can use this mark going forward as a reference for where the #1 plug wire should be installed around the cap. Marking the cap with cylinder numbers is also good but you will loose these markings when you next change the cap. _________________ AshMan40

The top center case stud is missing a nut as well. |

In Glenn's pic above, 034 is on the left, 009 is on the right.
And yes, that case stud was missing a nut.
I was originally going to mount the coil there, but didn't, and forgot to put the nut on. _________________ *ASE Recertified Master Automotive Tech*

Turning the engine backwards as a shortcut for adjusting the valves, probably.
Firing order is also cast into the gen/alt pedestal. "Zundfolge." |
