Does the vacuum advance get constant vacuum or not?
Manifold vacuum usually. There may be some instances where someone reworked a distributor to arrive at a specific timing curve under load using ported vacuum with the vacuum advance, but this would be rare as most people would re-curve their distributor by changing advance weights and springs and would limit the advance built into a distributor so they could use more initial timing without having the total timing go over 36-40 degrees when the engine is revved up and all advance is in.
Can you run lean distributor without vacuum?
Yes, you can run a lean distributor without vacuum advance, but it may lead to suboptimal performance. The vacuum advance helps adjust ignition timing based on engine load, improving efficiency and reducing emissions. Without it, the engine may experience timing that's too advanced or too retarded under varying conditions, resulting in rough running, poor fuel economy, and increased engine heat. It's advisable to tune the distributor carefully if operating without vacuum advance for better performance.
Why does your 76 nova not stall when you remove the vacuum line from the distributor?
It won't. That vacuum line tells the distributor When to advance the timing. There isn't enough vacuum loss to stall an engine.
What is a vacuum advance mechanism?
A vacuum advance mechanism is a component in a distributor that uses engine vacuum to advance the timing of the ignition system. This helps improve fuel efficiency and engine performance by adjusting ignition timing based on engine load. By advancing or retarding the ignition timing, the vacuum advance mechanism optimizes combustion for varying driving conditions.
Ignition timing for 1600 beetle?
I really depends on what distributor you have on the engine. It could be a mechanical advance distributor or a vacuum advance distributor (stock). Google "the Somba" Volkswagen forum and all will be explained.
What is the reason for vacuum at distributor?
"VAcuum advance". Step on it, vacuum goes down and it advances timing for more performance/power. Idle of letting off, advance goes back to setting for economy.
Does hei distributor require vacuum advance?
A High Energy Ignition (HEI) distributor does not strictly require vacuum advance, but incorporating it can enhance engine performance and efficiency. Vacuum advance helps improve fuel economy and throttle response by adjusting ignition timing based on engine load. While many HEI systems can function without it, using vacuum advance is generally recommended for optimal performance in most applications.
How do you set the the timing on a 1967 cadillac deville?
Connect timing light to #1 spark plug and battery Remove and plug vacuum line to vacuum advance unit on distributor Mark appropriate timing mark on crankshaft and stationary reference Loosen distributor cap slightly Start vehicle and aim timing light at timing marks Rotate distributor to align marks Tighten distributor cap when marks are aligned Reconnect vacuum line
What is the distributor vacuum advance location on a 400 Pontiac?
The distributor vacuum advance on a 400 Pontiac is typically located on the side of the distributor housing. It is connected to a vacuum source, usually from the carburetor, which helps adjust the ignition timing based on engine load. This advance mechanism can improve performance and fuel efficiency by optimizing timing under various driving conditions. Always refer to a service manual for specific details related to your vehicle's year and model.
Do you disconnect the vacuum advance to set timing?
Yes, it's generally recommended to disconnect the vacuum advance when setting the ignition timing on an engine. This ensures that you are measuring the base timing without any influence from the vacuum advance, which can vary based on engine load and speed. After setting the timing correctly, you can reconnect the vacuum advance to allow it to function properly during normal operation.
How do you reset the cam timing and ignition timing when youv removed the distributor from a 1977 Chevy 305 small block?
cam timing will not change ignition timing i would try 8 or 10 degees advance at idle with the vacuum advance disconnected.
How to set the timing on a 1984 Buick Riviera?
Install timing light on #1 cylinder Remove and plug vacuum advance line from distributor Highlight timing marks crankshaft and stationary Loosen distributor hold down Start vehicle and move distributor to align marks
