I have found an article that explains this a little better: http://www.rodandcustommagazine.com...hrower_distributor_chevy_engine/photo_06.html
Okay, verified TDC. I had a friend plug the hole with his finger while I bumped motor. The index mark was sitting right about 12* BTDC, so I manually rotated engine until he said it was TDC (was actually at 4* BTDC). Will setting everything up with the motor set at 4* BTDC cause it to not fire? Rotor was pointing at number 2 cyl, so I routed the plug wires from that post on cap as my number 1. I redid my lashing on all valves, I really screwed that up the first time. It is amazing when you actually read and follow directions. Reconnected everything and tried to start, nothing...Well, battery died. I am getting fuel, residue on plugs and I can see it spraying in carb. As far as spark, I can only assume because I do not know how to test for it. I have replaced all portions of the electrical side as I can with the exception of the distributor. Spark plugs are all gapped at 40. On the compression side, can I test for compression with the motor not running. I have a compression kit and was told just to screw it into each plug and bump motor 3-5 times. Does that sound right? Quickly running out of ideas, starting to worry about cam being flattened.
I disagree with the comments highlighted in red.
-When your buddy plugged the hole with his finger, (I use a wine cork because I usually do this alone.) When the compression stroke pops on #1 you should be at TDC. Don't manually rotate the engine, leave it right there.
-With the engine staying right there take off the dizzy to see if the button is under the #1 spark plug wire. Don't your dizzy cap have a #1 stamped on it? You would adjust this by loosening the dizzy hold down bolt & spinning the dizzy until the button is at #1.
Now that you mentioned it check your firing order (mine is stamped on the front center of my engine under the thermostat housing) and make sure the spark plug wires are in the correct order going clockwise.
- To check for spark, remove the #1 spark plug wire, hold the end about a 1/4" away from something grounded like the frame rail or a bracket. Have your buddy bump the starter and you should be able to see the spark arch from the spark plug wire to the ground. Don't put your hand on the metal when doing this or you will get a jolt.
This is how I have done it in the past & I know it works. I do all this without even looking at the timing mark, I only use the timing mark after the engine is running to set the final timing at idle.
- I would set the spark plug gap at .35.
Good luck, I hope you get it running soon.
I have never located a mark on my dizzy, just able to look at rotor and see where it points and place wires appropriately.
As far as adjusting the dizzy to make the rotor point at cyl 1, do I just spin the entire dizzy around in a clockwise direction until the rotor points in the correct location?
My firing order is 1-8-4-3-6-5-7-2.



Ok, I love the cork method up until you lose the cork, LOL. Found TDC, installed dizzy, redid wires and it breathes. Runs very rough but it runs. Now I can redo my timing and lashing and hope it stays running. Thank you for everyones help. I will keep you posted on the status.



Ok ok, I will say it....ktmoutfront you were right!!!!!
Gotta give credit where credit is due.
