Test Results - Crab Dist on my Allen Synchrograph
 

Finally got through “testing” a non-rebuilt/as-is Crab distributor on my Allen Syncrograph (Model E-316HD). I purchased this machine 5 yrs ago in Rochester, NY and. Only got around to actually seeing if it truly worked starting last week. I mentioned in this thread, that I would follow-up with my observations.

I’m a complete novice when it comes to testing these types of distributors, and it was a bit of a steep learning curve, and still is. The machine has issues such as a burnt out neon bulb (one of two), a non-functioning tach (works but is inaccurate), but despite those issues I was still able to get speed data with an optical tach, and the one bulb was just sufficient to read the flashes on the degree wheel.

I did purchase a photocopy of the manual off of eBay several years ago, but it was of poor quality in terms of quality of images, cropped pages, and missing pages. I did find other copies of the manual on-line, as well as other literature related to the Allen Syncrographs. I’m willing to share that info with others who request it to help support those who are going through what I just went through trying to get this one working. I do have this thread on the HAMB as well going over them”restoration” of the machine, including the results, but will summarize just the test results in this thread.

I’ll post details of the results later this morning hoping it will prompt experienced folks with these machines/distributors to comment on what I measured, what I did right, and what I did wrong. Haha!

I'm curious what you found. I go through the front mount Ford distributors with good results, but have never had one on a distributor machine. I'd be curious to see the difference between a machine set unit and one I do.
