time to tune it in!

[hbryant123]

I have a 1974 105 chrysler. I have it running to wear its reliable and starts every time. I am wondering how to set the distributor to were its perfectly in sync with the carbs? also it will occasionally pop out of gear i have adjusted the locknut thing on the rod that runs into the lower end. I was wondering what els can be adjusted? also i have the us marine controls that come with the boat they feel cheaply made and have play in them. Would it be worth it to go back to my old quality chrysler control box??? thanks for any advice

Re: time to tune it in!

You don't sync the distributor to the carbs, you sync the timing to the carbs. The distributor is set to be at #1 cylinder (top) when the flywheel is at the TDC mark in neutral. To do this,with the flywheel at TDC you loosen the distributor mount and turn the pully so the curved line matches the curve of the flywheel and the straight line points directly at it. Then snug the belt and tighten the distributor mount bolts. The belt should NOT be too tight or the engine will have shifting problems. A .010 feeler gauge should deflect the belt about 1/8 to 3/16 inch before bending when pointed at the center of the belt like a finger.

I like the Chrysler control boxes, especially the hidden ones with just the handle showing. BUT, I also use the US Marine boxes with no problems.

To sync timing and carbs, see the sticky at the top of the forum. Although it was written for Prestolite ignition, your distributor ignition is very similar. The main difference is the timing link is attached to the distributor body.
