Wrong keyway and wrong dot used gets the crank off some 120° +/- in either direction.

Appears TAQuest has his crank just right. Fuel pump eccentric will point to the right with the engine timed on cyl #6 (dot to dot). Fuel pump eccentric would be pointed straight to the left if he turned the crank one turn (both dots up) and it would be timed on cyl #1.

The 4° keyways takes very little crank movement for the new dots to line up.
4° out of 360° ain't much.

Does appear he has things set right where they should be.

The not wanting to adjust/reset the carburetor now that the engine is in time doesn't make any sense to me. Cam "off" like it was would have had carb adjustments "way off" for the engine to idle like it did.

Haven't seen any comments on how the engine runs now if you rev it up. Just that it wont idle now.

I will go though this again piece by piece to bring you along but I'm just wasting time typing.

I know timing. I have been messing with timing for how long now? 30 plus years my friend! So have a little confidence in my ability to time an engine.

I know how the engine timed with the dots NOT lined up. It timed normally. Get it close so it will start and idle then fine tune it. Works every single time. I have a bunch of old cars and trucks. They are all timed like that and they are run great.

When I lined up the dots and tried to time it I could get it to start but it would not fine tune. The timing was always off no matter how much I fine tuned it.
After a half an hour of fine adjusting I knew the move I made was wrong.

Can you see now that lining the dots up was the wrong move?

Thanks for your help.

Cam advanced like it was the engine didn't run right at all except for idle.

Cam advanced like it was had valve events happening way too early.

Advanced valve events had the engine pulling 2~3 times the idle vacuum it does now.

Doesn't matter how much you "fine tune" ignition timing, with the distributor, when the carburetor adjustment for idle can't even be close to right.

Your first timing chain pic showed crank gear was off at least two teeth. That is not a degreed cam it was some ones mistake. As posted earlier...Does appear that you have it right now.

Clay,
Do you really think that someone who assembled this whole engine from a kit couldn't get the dots lined up? Seriously? You are very stubborn.

On top of that you think that something as simple as 'idle' was stopping me from tuning it? I would be inside the car with my foot on the gas. Not just letting the idle screw do everything.

If that is the case (and I don't, I believe the cam was installed wrong) then why was the engine done at 3200 RPM?

Worth saying again

Definitely needs a better cam, but sure would be nice to find the issue first.

Why? I don't know. If it was cam related then we will be fixing that. If it was not then we will fix that too. Cam first. One rock out of the field at a time.

Just saying what I would do if it was my field and my rocks. lol

But it is your field and your rocks. Good Luck

Yup.
Maybe a $17 timing set from a warehouse that would close soon after they sold it was funky and the dots were wrong? Or the cam was ground wrong.? Hang your hat on that rather than thinking that all the mechanics working on the engine were wrong.
