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.
