I have been trying to get this evil thing started for too long, 12a. I have compression all over 80. I have spark. I have fuel. I have a clean carb. I line up pully, should the pully have two indicators? I lined up the distributor. I do get constant pops but it wont run. Tonight I had some pretty major booms coming from the exhaust. What should I do? Find a nee hobby? The pulley has a rivet on it, I believe it's in correctly. I read I can remove the platebon the passenger side and check timing there? Like I wrote prior, I am a novice. It is quite possible I did something wrong in the rebuild.

 

Sounds like it might be flooded. Did you pull the plugs, clean em, and clear out the engine by
spinning it (fuel and spark off/disconnected) ? Sometimes a bit of oil in the chambers helps that
first start. Also some folks pull start a fresh engine.

 

I actually did clean the plugs, a couple times but I'm sure it could use it again. I have been using mixed gas and starting fluid. I checked all the resistance on all the plug wires and they are all ok. I have tried many timing settings, I marked off every few degrees on the timing pulley. It never seems to be that close. I've had a lot of back fires but last night I had one that sounded like a bomb. I thought I was going to need the fire extinguisher.

 

Sound like your timing is still no right.

 

I agree but if its firing, it has to be close. Right? If I removed the access panel on the passenger side, what do I line up? Is there something on the flywheel?

 

This may help

Also check compression.

 

if you have spark and not flooded, set the timing at tdc, re-stab the distributor (of course marks need to line up). if it cranks but no start, fuel or carb problem.

 

How else can I set tdc without using the pulley? I am getting fuel, I am using starter fluid sprayed directly into the intake. I have new wires, plugs, rotor, cap, igniters. I am getting spark. I have compression. One thing I am getting is some pretty insane backfires, bomb like. My timing has to be off. I know i could have installed the distributor pulley backwards. What way is the keyway under the pulley supposed to face at tdc? I have read 90 deg off tdc, 9 o'clock? It's not in me to quit, if I can't get it started, I will take it out and tear it down again.

 

The flywheel cut out will line up with the intake when at TDC. The pulley marks should be close to lining up with the marking pin. Look closely, there will be two marks on the pulley that should be really close. If not, you will need to adjust the pulley on the e-shaft until close. Pull the distributor and make sure the dots line up. Reinstall, start engine, time engine, done.

 

My pulley only had one mark on it. I say one because I marked off every two degrees up to 20, advance. I will check the keyway today. Thanks for the help.

 

I also market a line on the dizzy and rotor lining up when the dots line up. I know I had the dizzy correct.

 

use the stock flywheel to set your timing. once set, the 10mm bolt on your pulley equates to 0. re-stab ur distrubutor.

 

It would sound like you are firing early pre compression. aka 45 degrees off on the timing. you said u have a 12a... 4 ways you can try your timing... best bet would be to take off the side viewport and align the FLAT side of the flywheel. FRONT side of the flywheel (facing engine) will have a section that is 'missing' this section is flat and will align to the side of the rear iron and will be TDC this only works on the factory/stock flywheel.

edit please note once you turn that flywheel around and look at the front facing side you will know what needs to be aligned.

 

When you say this will be tdc, do you mean on the pulley? So I would rotate the pulley 45 deg clockwise? I really hope so, if not I was already there, the area on the flywheel is left the mark on the pulley is up. I didn't get everything back together tonight to try, hopefully tomorrow.

Thanks, I really do appreciate the help.

 

use a 19mm socket to rotate the motor until the flat end of the flywheel line up with the inspection area on the rear engine plate. search under my SN on how to set the timing using the flywheel.

now look at the front pulley. the 10mm bolt at 12:00 is your TDC so check if the timing mark (far right if your facing the engine) line up with the pointer on the front cover.

line up the marks on the distributor gear (not the roll pin) and restab it

 

I think I have it. The pulley was 45 degrees off. I don't have a working fuel system yet so I had to settle for starting fluid but it sounds good. My holley fuel pump should be in the mail so hopefully I can take a spin around the block next weekend. Thanks for the help, I would have never guessed the pulley would have been on incorrectly.
