Hi All,



So I attempted to tune the DC3 today but think it is wrong and
sparking on exhaust on one of the cylinders



Anyone have the Later Model DC Timing Procedure handy?



I tried to follow timing similar to an SC - which says to line up
advance 25 degrees (hole in flywheel) then hand turn the impulse
until #1 cylinder sparks then put magneto in tractor without
adjusting anything.



Well, I did that and think it is firing on exhaust.



Flywheel only has a D and I can measure out any advance on the
impulse coupler as it fires in horizontal.



Thanks

those tractors have the big D that you line up in the centre of the hole on compression stroke on number one cyl. then you line up the mag slots with rotor points to number one cyl. then bolts it on not completely tight. then crank it SLOWLY one turn till it clicks again and STOP and see where the big D is in the window. adjust the mag using the slots to get the big D centred in the window. thats it. you do not have advance with the mag or it will kick your azz, actually your wrist or arm!! meaning break it.

Hi Rustred,

Apologies but I think I am a little confused.

If I put the engine at TDC on #1 and point the rotor at #1 cylinder - the next cylinder to fire will be that #1, right?

So when I crank it over one click, wouldnt that mean cylinder #3 is TDC even though I just fired #1 spark?

If yes, then you are saying to reverse the flywheel to bring the D back into the window, ie #1 is TDC again and #1 just fired?

If this is correct, I wonder what I did wrong earlier cuz I set it at TDC with the D in the window - then turned the rotor to my #1 plug and hand impulsed the set on tractor

#1 cylinder is the one farthest from the radiator, yeah?

Did you have #1 on compression stroke? Sounds like you are 180 degrees off.

Hi Case,

Yeah, I think so too.

The previous owner said he couldnt get it running so I got a good deal on it and from the things I have noticed so far, it wouldnt shock me if the plugs were in the wrong order (I have them how I received them).

But on thinking about it and while I am not sure, but for Case DC tractors, wouldnt the #1 cylinder be the closest to the radiator?

i said one turn or revolution. all you are doing is getting the D in the centre of the window with the #4 cylinder.

geez, not only case but all these old tractors #1 is at the front of the engine. tell me why you would ask this question. appears that is why your having so much trouble. and more info. left of the engine is ALWAYS as sitting on the seat, standing behind the tractor ,or looking at the flywheel from behind. same as firing order, ... most 4 cylinders are 1342 on most old and new tractors.

and also, there is no i think so... with plugs out and a paper towel plug in the hole while turning it over with the crank the plug will pop out as its coming up on compression. that is a guarantee on compression stroke. have you done that? there is other ways but you will get further confused. put paper plugs in all 4 holes if you want. crank it over and watch them pop pop pop pop out in the firing order. thats as simple as i can describe it.

Hi Rusty,

You are saying there is a D in the window for the number #4 cylinder as well?

I thought there was only one D on the flywheel, specifically for just the #1 cylinder, but it sounds like you are saying there is a D mark for every cylinder?

The D on the flywheel come up whenever number 1 and number 4 piston is at top dead center.To time the #1 piston MUST BE on Compression stroke.The #4 valves will be on the rock,meaning exhaust valve is is just finished closing and the intake valve is just starting to open.
The #1 valves will be both closed on the compression stroke anytime the piston is on the up stroke and down stroke.
Stick a paper towel or rag in the #1 plug hole and when it blows out it is coming up on compression stroke.then line up the D in the timing window.Get the mag ready to fire the #1 plug wire (note location of the drive tang) let the impulse click, then back up to where the drive was before impulse, Install the mag just snug and start engine

Hi Den,



Thanks for the breakdown, much appreciated.



I followed your post and got the magneto timed - went to start and
still nothing.



This time, I decided to cheat and sprayed a little starter fluid into
each of the plug holes, then went to fire it up and puff puff puff :)



so at least I know I am igniting but now onto the carb to ensure
good fuel vapor

Try some starting fluid into the carb intake while trying to start it.

i dont think u understand. there is ONLY ONE D on the flywheel. if you have number 1 cyl at TDC compression with the showing and give it ONE COMPLETE REVOLUTION , that same D will appear in the same window again with #4 cyl. being at TDC. give it 2 revolutions and you are back to #1 at TDC. PISTONS ON CYL'S 1 AND 4 WILL ALWAYS BE IN THE SAME POSITION AS THEY ARE RUNNING MATES.

You said
that same D will appear in the same window again with #4 cyl. being at TDC. give it 2 revolutions and you are back to #1 at TDC.

I know you meant to say 1 revolution and you are back to #1 at TDC.

I think the difference here is that on only one of those turns will #1 be on the compression stroke while #4 and#1 both will have (D) in the hole at TDC. That wasn't stated as maybe it wasn't important to that part of the conversation.
