I know the timing is 6 degrees Before TDC but I don't know what the idle RPM is.. I'm trying to find that myself right now...
A general number for timing is around 10 but that can change based on the engine setup. The idle speed also depends on the set up but its about 900-1000 and 700-800 in gear with a stock engine.
Ignition Timing degree B.T.D.C at idle speed 20 degree plus or minus 2 degree

autozone.com has online manuals that give you all that info Also just look under the hood. There you will find a placard with this some if not all this information.
I don't know I'm also still searching the answer for this question.
1 8 4 3 6 5 7 2 An oldie, but a goodie- have fun. The ignition timing is 4 degrees before top dead center. Adjust the point dwell to 30 degrees and the adjust the idle speed. then disconnect the vacuum to the vacuum advance and set the timing. Reconnect the vacuum and fine tune the carburator. With an upgrade to electronic ignition and with running todays gas (low octane) a bump up in timing would be recomended. Try running about 6 degrees after and see how it does would not go above 12 after.
There is no provision for setting the ignition timing. The timing is set by the computer by way of engine sensors sending signals to it by such things as temperature, load, speed, and intake air.
10 degrees before TDC
On a 1996 Nissan pickup with a 2.4L engine, the timing mark line 0 for ignition timing is typically located on the crankshaft pulley. You can find it aligned with a timing pointer or notch on the timing cover. To set the ignition timing, you would rotate the engine until the mark aligns with the pointer at idle speed, usually while the engine is running. Always refer to the service manual for specific details and adjustments for your vehicle.
Check for vaccuum leak. Check ignition timing Check timing chain (may have jumped) Check for restricted exhaust Transmission? Clutch slipping? Plugged air filter? Plugged fuel filter?
To adjust the timing on a 750 Intruder, you need to first locate the timing marks on the engine's flywheel and the ignition timing cover. Use a timing light to check the current timing while the engine is running, and then loosen the ignition timing plate screws to rotate the plate for adjustment. Rotate it slightly counterclockwise to advance the timing or clockwise to retard it, then retighten the screws and recheck the timing. Always ensure the engine is at the correct idle speed and temperature for accurate adjustments.
The ignition timing specification for a 1972 Oldsmobile 455 engine typically ranges from 4 to 10 degrees BTDC (Before Top Dead Center) at idle, depending on the specific model and factory settings. The idle speed is generally set around 600-800 RPM when in gear. It's important to consult the vehicle's service manual for precise specifications, as they can vary based on factors like emissions controls and any modifications.
