Motor won't run

[mightynova63]

I have a 1928 sport coupe that I'm trying to get running. I 99.9% sure on the timing 99.9% on the carb I rebuild and I have good compression. I replaced the oil pump drive gear that was extremely worn, installed an updated pionts system and rebuilt the carb. The motor is spitting and sputtering but won't kick over. The head is getting warm and the plugs are kinda dry. It has plenty of turning power with the 12v upgrade. Right now I'm leaning that the carb is not feeding the right fuel flow or the coil is not powerful enough. Any help will be great.

An updated ignition system congers up mixed pictures in my mind.
I have successfully got original configured motors going using the basic parts then I could start modifying. A picture of your project motor would give us a place to start from.
You can test for spark and good fuel flow as a starting point.

if it is fuel it will run ok on a shot of starting fluid.

I don't have a pic of the distributor but is is a normal nu-rex system.

I have spark but still nothing with starting fluid other then spitting and sputtering. I have built race cars for over 20 years and this little motor is killing me lol. I have spark, compression and fuel it should run but nothing.

Need a good spark at the right time.

Did you set the timing with the lever set to full advance and not full retard

 

[mightynova63]

Full retard

If it wont start with starter fluid then it is not a fuel problem. Sputtering and just won't catch tells me timing.

Could the timing somehow be 180 degrees off?

Pull the side timing gear cover and check the condition of the large timing gear.

where do you have your GAV at if it's closed?

open the GAV up about a full turn and see what happens
had one that would not run tell i did that

Full retard

Spark lever should be all the way up when setting timing

 

[mightynova63]

The gear is good.

If the timing pin drops into the cam gear dimple, and your rotor is in this exact position, then the timing is great. Your points gap looks good.

 

[mightynova63]

So it looks close. I'll check that when I get home but that's a picture I took yesterday.

Looks like it could arc from the condenser nut through the rotor contact to the #1 plug contact.

Is the fuel line pushed too far into the carb?

After re reading other posts I see that you have spark so this info is not needed ...


Is this nut OR any tabs, lugs or wires attached to it below touching or very close to the dist casting?

Can not post photo with arrow pointing to part ...

Referring to photo in post 16 with orange wire.

Talking about the NUT under the brass part of the rotor ....

does the timing gear spin when you crank the engine
