Re: Need help to set timming
... I've never worked on a carb and dist engine in my life.
You must be a youngen'....
Checking the timing is quite simple on your engine. It's a Thunderbolt IV system, so no 'base mode' to set up...
I assume you have the following tools (and know basically how to use them). Timing light (best to have one with a tacho built in), a hand-full of AF spanners, assorted screwdrivers...
Connect the timing light to the battery (assuming it's a 'powered' timing light) and the pick-up to the spark plug lead of #1 spark plug. There may be an arrow on the pick-up, that should point towards the spark plug. Start the engine and let it warm up. Make sure the idle speed is down around 650-700rpm. Now point the flashing end of the timing light at the timing marks on the engine front cover. You see a line on the crankshaft pulley that appears to freeze with the flashing of the timing light. That line needs to line up with the indicator tab at the 8 degrees BTDC (before top dead centre) mark. If it doesn't, you need to loosen the clamp plate holding the distributor down and carefully turn the distributor until the line on the crankshaft pulley is in line with the 8 degrees BTDC mark, then tighten the clamp plate bolt and recheck the timing.
The service manual you need is
THIS one... Have a look at section 4B, page 17....

BTW, your engine serial number is missing a digit....
