Spark Rod Adjustment
'29 CCPU runs great, but...
What do I need to adjust in order to use correct 17" Spark Control Rod and get full spark advance? With bent rod I get full retard & full advance. With 17" rod, I don't have enough arm movement to get full advance. I have Model B motor and can't rotate steering column. Suggestions greatly appreciated. 17 in. Rod.jpg 17 in.

Re: Spark Rod Adjustment
Looks like you have the forged arm upper plate. I think I read in the Service Bulletins
that the early arm is narrower than the later stamped arm so the earlier slot in the cap was narrower. Bob |

Re: Spark Rod Adjustment
Is there a way to take the ends off of the rod, shorten the rod and re-install the end?

Best solution might be to buy into the "adjustable" link mentioned - or possibly "bend" the rod? I have seen MANY bent rods. Up to a 20 degree bend. You might get creative and heat it up and bend the straight portion into a small circle - just for decoration. If you make it too short, you can heat an and "forge" it longer per blacksmithing skills using hammer and vise pad. Joe K

Re: Spark Rod Adjustment
Loosen the tank steering column bracket in the car
Loosen the clamp on the bottom of the steering column Turn the steering column to adjust the rod. Works all the time |

Re: Spark Rod Adjustment
Can you not bend the small lever at the lower end of the steering box?
