Hi Folks,
Happy Labor day weekend. Would appreciate any
help on the following question. Have a standard
brown jet star. Plug wires were removed. Looking
at the operators manual it looks like the firing
order is 1-3-4-2. in the book it shows the dist cap with the plug wire holes at 12,oclock, 3 oclock 6 oclock and 9 oclock ( looking at it from
the left side with the radiator to the left.
When I look at the tractor from the same view I
have plug wire holes on the dist cap at 10 oclock
2oclock, 4oclock and 8 oclock, there is a wire that
goes from the coil to the distributor that is at
4 oclock, My question is where do I start with
plug wire #1 and do they go in consecutive order
clockwise or something else.
I was looking at my dads well worn operators
manual page 78.
thanks very much for any help and God Bless!
Jim

Page 78 in my manual is a sketchy attempt at a wiring diagram. It shows firing order 1 3 4 2 clockwise. I believe the Jet Star Four Star series are counter clockwise.

Position of the distributor can vary depending on how the shaft is set when it is inserted in the engine so clock position compared to manual should not be a concern.

Remove #1 (front) spark plug. put finger over plug opening and rotate the engine. Observe direction of distributor rotation. When compression forces your finger from the hole you should be on #1 compression stroke. The distributor rotor should be pointing at one of the plug outputs in the cap. Put #1 plug wire on that port and continue with #3, #4 and #2 as it rotates around the cap. If distributor had not been moved you should have it set.

I hope I am reading you correct. I looked on my jet as well. The + wire from the coil to that feeds the points is a good place to start this at. The #3 cylinder plug wire would go on just in from of that dist post or to the left of it on the cap if standing on that side. That would be clockwise and while going clock wise #1 then #4 then #2. The distributor turns counter clock wise and this post reads a little strange but hope this gives some kind of point to start.

I would do all that and check the fly wheel for timing marks.

Many smiles!!!
Went to the farm yesterday to work on the jet
armed with My new info. Turns out the Manual
is printed wrong on page 78 it turn counter
clockwise not clockwise. Took out #1 plug and
my compression point was at 2 oclock for #1
(I was at 8oclock for 1) continued on Counter
clockwise for 3,4 & 2. Runs smooth! I think
My Dad would be smiling from above, Many thanks
to Rvirgil_KS and Kevin Moschenrose for your
help! Time to put it to work and make wood before
the snow flies.
