New coil is on. It can hear it start to catch but it just doesn't. I have to go to work but this weekend it should be up and running.


I'm thinking the issue now is timing. I'll find tdc again and verify correct rotor placement.

Unless you guys have any other suggests it might be.

I out starter fluid down the carb and it wanted it bad but couldn't get it.

So now you are getting spark to plugs?
If so it is timing.
A slight twist of dizzy should get it close to starting, then time it.

Original plugs gapped to stock length. I think .035.

Yes spark to plugs.

I can increase gap, I wasn't going to change plugs until I get the new carb on.

You can increase your plug gap to 0.40 or possibly even 0.45

I just got home from work. Do you think the timing needs to be retarded or advanced?

Lol. I have no idea. It all depends on how close it is to tdc. When i stab mine, i mark where it sits so that im fairly close to original.
If it wanted to start, it might be sitting atdc, so it needs to move to tdc or btdc.
Remember, typically it runs good at 8*btdc

I advanced it. Its almost started. Unless I hold the gas pedal down it won't stay running though.

Try advancing a little more. Small turns.
Was it running good before you messed with it?

Was a tired 4.2. Ran decent I wouldn't say good.

Got it to run. But now I have to figure where to install these resistor to prevent run on.

Got it set to 8btdc. But it seems off. I'd need a pro here to tell.

I might refund tdc and reseat the dizzy.

Yeah I can't figure out this diode. Where do I need to install it? I dont want to get it in the wrong spot.

How is your install coming along?

If it runs, reseating dizzy wont change anything. You cant pick up a tooth except for dizzy clearance.
Carb adjustment?
Resister goes in small brown wire on clip that comes out of top of alternator. I hear its a pain to solder in. I googled soldering diodes to stranded wire. They said to "tin" the wire first, then install diode

I just finished soldering mine. Man it was a pain.

It just seems off. Probably just me.

Would the engine run if the rotor was closer to the 2nd terminal than the first at tdc? Just curious how off it could be and still run.
