control connection block and carburetor control rod question

[Steve Swan]

I'd appreciate if you could answer a few questions for me. I am helping a local buddy get his 29 together.

Re: 1929 JD model, the various throttle/oiler control parts. I've been reading the parts book and would appreciate if you can tell me if my understanding of what i am reading is correct.

If i understand correctly, for the 29JD, the parts book calls for the 3368-28 control connection block, the 3363-28A carburetor control rod, the 3370-29 carburetor control connection, and the 1238-24 throttle lever.

I'm trying to understand the relationship between the throttle/oiler control wires and the control connection block, the control rod, the control connection, and the throttle lever.

1. Does the 3362-28 control block connect the throttle and oiler control wires ?

2. Does the the 3363-28A carb control rod attach to the 3370-29 carb control connection and this connection attaches to the 1238-24 throttle lever ?

An ebay seller has control blocks and rods for sale. He says they will fit the 29JD. However, the pn's he has available are not what the parts book calls for.

1. The 3363-29 block seller has for sale, parts book says are for 30-31 twins.
2. The 3363-28 rod seller has for sale, parts book says are for singles and 45's.

3. My question is this - Will the seller's 3362-29 block and seller's 3363-28 rod work for the 29JD, given parts book calls for pn's 3362-28 block/3363-28A rod for the 29JD?

Here is seller's ebay auction - https://www.ebay.com/itm/HARLEY-LINK...JXCQNK&vxp=mtr

Here's how it sits on one of my spare 1929 motors.
The first two photos show the bracket and wire as attached to the oil pump.
The third photo shows a general view of everything up top.
The fourth photo shows the bracket, connection block and wires as they are connected and are mounted on the front cylinder.
The fifth photo shows the throttle block and throttle arm.
The final photo on the next post shows the bracket that holds the oiler wire on the rear cylinder.

Tommo, Thank you very much for taking the time to take these pictures and post them. They are very helpful.

In the first photo, what is the control coil for that appears to come out the bottom of the oiler?

What DLX number is the carburetor on your engine?

I'm not in New Zealand looking at Tommo's engine,but I would guess that is the extra length of the control coil for the distributor that is simply wrapped around the engine. It looks like it wraps around the front and then is tucked in behind the gearcase.

Tommo
Thanks from me also. Great pictures of how that rat king is all connected.
I've always found it odd that the front 1929 coil bracket is available as a reproduction but that the rear is not.
The rear also seems much more difficult to find in the bottom of boxes at swap meets whereas the fronts pop up from time to time. Got a box of spare rears on the shelf where you could spare a few?
Thanks

[Tommo]

Mark's correct.
The spark control coil is looped around the engine.
Carb is a DLX58

[Steve Swan]

Tommo, from what i understand, and i may be wrong, it seems there is not certain clarity what DLX number was fitted to the 29JD. is this true? is the DLX58 the correct carb for the 29JD. my buddy is using a DLX55, that Tom Cotten so masterfully rebuilt and conserved to JD specs. And, again, thank you for sharing the pics of your 29 engine.

Thanks Mark, for your reply. my buddy has a rear bracket repro, but i do not recall it having the 2 pieces held together by a screw. i will do a bit more researching top see what he has.

Before I make an educated guess with regard what carb is right for what model we need to be very clear as to what bike we're talking about.
61" J model or a 74" JD.
All to often people ask questions regarding a J model but call them a JD.
This is not right and causes confusion.
Most but not all parts are common to both bikes so before I answer your question I wish to know exactly which model you are talking about.

[T. Cotten]

...my buddy is using a DLX55, that Tom Cotten so masterfully rebuilt and conserved to JD specs...

Just for clarity, Folks!

I conserved what was sent to me, specs aside.

As Steve notes, the literature varies greatly upon what is "correct", and many existing DLXs are un-documented, so far...

"Correct" is an existential problem for the judges, not me.

I am referring specifically the JD models, 1929 in particular.

Fully agreed Tom. The DLX55 you rebuilt was the only carb my buddy had and he knew it was most likely not the DLX model number for the 29 JD. He was just glad to have a carburetor to send you.

Now we're getting into the fascinating subject of undocumented brass Scheblers used say 1929-31, and I'd appreciate fresh insights. The 1928 Schebler overhaul manual shows the DLX 45 used on the 1928 JD with the DLX 48 on the Police model JD. This list also shows the DLX 38 for 1927 and the DLX 53 for 1927 racing and hill climbing. Original mid-1930 VLs use the pot metal DLX 80, with contemporary Indians taking the pot metal DLX 77, 79 and 81. That leaves the brass DLX 58, 66 and 72 as the remaining ones most commonly seen, which by inference would have been used on the 1929 and early 1930 JD/VLs. These are all three bolt 1 1/4 inch units like the DLX 45s, which is the one I see most often. Would anyone like to step in with info on carburettors from original 1929/30 big twin Harleys?

Well Steve,

There is literature out there somewhere (as per Yarocki) that says that the potmetal productions started in June of '29 (I have had both bronze and potmetal Hen DLX76s across my benches.)

To further muddy the water (but ignoring 1" Models for now), there are unspecified bronze DLX61 and 67s out there. Mystery models abound.

Until a Schebler Rosetta Stone appears, we can only be forensic.
Logically, we must presume any '30 bronze Scheblers installed by H-D had to be left-over stock, used by convenience or cost advantage.

The factory was not as concerned about its legacy as we might be..., so the judges may never come to agreement with the fossil record.

I've got two 1927 J's as well as a 1928 and 1929
With the exception of one 1927, which has a HX181 fitted they all have DLX 58's fitted.
There are two very original 1929 JDH's here in NZ and both are fitted with DLX 58 carbs.
So we have 3 J's and two JDH's all fitted with 58's but we have no JD's to add to the mix.
My 1929 J was owned by the Service Manager for the South Island HD importers from new and I am the second owner of this bike.
It is very original machine and Herb was a great one for not changing things so I'm pretty sure the DLX58 on it is the correct carb.
So my educated guess is that most if not all 1928 and 1929 HD J's, JD's and JDH's were fitted with DLX 58's
