1937 No start

sometimes its something sooo simple. Last night I built a 9N dist and bench tested it with good spark inspite of foreign made points and condenser that had to be "fitted". My son took it and put in on his neighbors tractor and nothing. They then discovered spark plug wires were off the plugs and plugs were loose. A little tighting and varoom!
 
been so long ago I forgot but has a differant working distributor been tried. Sure would rule a lot of questions.
 
If you check Macs Caps the wires are as TOMo in 121 post took the time to read off a cap and the are right.
Right Side Looking from fender.Number 1 is top left,2 bottom right,3is top right,4 is bottom left.
Drivers side viewed from fender bottom left is 5,bottom right is 6,top right is 7,and 8 is top left.
As I have been saying right along number 1 is innner top left or 11 oclock.
NOTE this is viewed with caps on dist "Not on bench."
also if they get swapped from one side to other it wouldn,t run.

Ya had to ask right . We are playing with both types as many of the cars at the Newport hillclimb use our ignitions.
A fellow barner sent me a email a few days ago and got the brain cells going. He stated that we shold use the 36 distributor with the dwell adjusting screw holes in the helment bottom and remove the "make set" of contacts and use only a single set of points. This to me makes sense and in the next couple weeks i will get one done and spun up.
Stay tuned .........
 
That should work Bubba, early Packards had dual points and a conversion plate is made for them now to convert to single common points. I put one in my 29 and it runs fine.
 
Bubba, Would it make any sense to put that distributor on a known good running engine to try it out, after you do your machine checks, before you ship it back to the owner? That way we could definitely rule out the distributor as part of the problem. JMO

No real advantage to using a live engine with the test equipment we use.I have side caps coming from Van Pelt and will run the entire unit with wires , loads and a view of rotor both visual as well as a scope waveform. At this point the distributor is pretty much perfect ( without wires and caps).
 
After reading this problem over from first post i,m still bashing the dist.
There is maybe one more thing that has been over looked.
The timing of the of the points.
Seeing the a 2 points you have a make and brake set.
So the dist turns counterclock wise and when the first set makes,
the other is made and when it brakes "AT that time a spark should be
at slot time,putting spark say 12 oclock and slot same time.
"The rotor maybe right"" but the points cam is off"
say cam was off 30 degs and cap off 10 dges being off 40 total.
If these are new parts they could be made wrong.
Slot time is TDC,spark has to be same time,and the rotor lined up with cap.
This can be done and NO Machine is needed turn by hand.
I hate after market junk sorry.

So what your saying Bubba is that the dist looks perfect except for the wires and caps,which we can assume the fella put these in himself. Points to wires in wrong or caps wrong which most of us have been saying all along.This is an interesting thread and very informative for all who are following it. Love a good mystry.ken ct.

Yep thats pretty much it. If for some reason the distributor had a problem , it certaintly doesnt now i have ran this thing to death a couple days in a row.
As far as anything being made wrong , twisted etc i have compared every part to the baskets full of the same unit more than once since i have had it.
I havent shiped as of yet as i want to see some waveforms on a scope with the side caps and wires attached, should get that done early this week and ship back to customer....
 
So he didn't send you the wires or caps which could still be wrong when he gets it back.And he will have the same problem.ken ct. I still think hes got the wires in the wrong holes. ken ct.OMO with out getting a look at the whole setup caps in place ,wires installed and in the tubes,the whole cheebang the way he installed them.
 
If the points fired late say 35 to 40 degs late the rotor would be close to #4 that cylinder would be close to bottom and fired late causeing to blow back thru carb on number 4.
The car did run and he didn,t mess with wires or cap.
That make sence to me but i don,t have dist.
 
Bubba is the only one to see the dist and he only got 1/2 of it.Could have been setup wrong by previous owner and never fixed?? ken ct. I would love to get a look at this thing [the whole thing wires caps and metal tubes] all attached to the dist the way he was trying to start it. ken ct.
 
"Points to wires in wrong or caps wrong which most of us have been saying all along." - ken ct.

( .... psst, Ken. You started out saying it was the power valve ... ;))

I got beer riding on this.

Well in his first post he stated it was backfireing through the carb. Its not good if hes running a 94. He never stated which carb he was useing.And still hasn't.That was a shot in the dark we all make mistakes LOL ken ct.:)
