I just got Big Black out of the brake shop. Took him home. Changed the oil and when I tried to start it and move him out of the garage, he cranks but won't start. I checked to see if the carb was getting fuel, which is was. So it must be spark problem. I looked at the roder and everything looked fine. What could it be? Coil, or Spark Plugs? It has a Malory Promaster Coil #29440. It looks kinda old though. I'm not sure how to test the coil without replacing it. Any thoughts guys?

 

-check the points
-check that there is 12v to the coil with the key on.
-make sure there is 12v at the I terminal (brown wire) of the solenoid when cranking

 

I changed the plugs and wires and she started right up. While it was in the brake shop they tried to fine tune the carb. Could that have fouled the plugs?

 

were the plugs really black and sooty looking?

 

They were black and had a really strong gas smell.

 

I guess somebody could make a snide remark about having a brake shop work on your carburetor.

Since you drove it home, parked it, and then changed the oil, it must have flooded while it was at home. To flood seriously enough to foul the plugs is fairly hard to do. They might have screwed up something with the float valve, such as forgetting to put back the retaining clip. You'd better keep an eye on it. Is it starting and running okay now?

 

It wasn't a brake shop. It was a local mechanic shop. They asked if they could have an hour with the carb to fine tune it and make it run better. Then when I picked it up I talked to the guy who tuned and he says, "I'm not really a carb guy" Then leave my carberator alone! Its runs rough when its cold. It wont even idle. When it warms up though it runs great. You think its a choke problem?

 

Sounds like the choke could use some adjusting, I'm having the same problem on mine.
