Getting my dads case 1960s 430 gas tractor going after idle for years. Rebuilt carb. Now spark is intermittent. Had to remove distributor as cover
would not remove easily. Have a j. I. Case shop manual..

I am new to tractors and ignition systems, but Trying to follow installation and timing in manual.

Which is number one piston? Forward or aft?

Does static timing procedure ensure the spec of 4 degrees BTC?

There is intermittent on opening and closing of points as seen from voltmeter on distributor to ground when cranking. Did new coil, points, capacitor.

What kind of oil/ grease goes into port on side of distributor?

Thanks for any help.

I can only address the 1960-64 430, dry clutch and the 148B engine.

#1 cylinder is closest to the radiator. Timing is 1342.

Careful static timing can get you close to TDC but can be way off. Tendency is to rotate distributor head to achieve a smooth idle which will invariably be 4 or more degs BTDC depending on carb and general engine condition. Use an induction timing light with pickup on #1 spark plug wire or the coil wire just above dist cap at engine idle rpm below 550 to set timing. Pic is timing light pickup on coil wire.

A light oil for dist lube oil cup, engine oil is fine. Light layer of dielectric grease on dist cam. Since you appear to be having intermittent dist function you should pull the plate and check out governor springs, lube flyweight pivots very lightly and check that movement is free. Springs should retract flyweight fully & smoothly. Pic.

Front piston is # 1. By aligning the pointer in the peep hole with the timing mark on the fly wheel, number one piston at top, and rotor pointing at # 1 wire on cap, you get a close setting. Final is achieved by moving slightly loosened distributor either direction. 30 wt oil for lube. It's much easier to have someone with a light looking for the mark on the fly wheel, spark plugs out, and someone turning the motor from the pto on the rear with a pipe wrench. Also a short piece of gas hose is useful to feel where # 1 piston is. When your done the wire terminal on the distributor should be about the 7:30 clock area.
 
Thanks, will try this weekend. Where is the reference mark to shine timing light at? I will replace the wire between distributor and coil, not high tension wire and verify no break in continuity between distributor post and contacts high side.
 
For 1960-64 430, dry clutch and 148B engine, I am not up to speed on the later 430 tractors.

Timing is the same location as this older tractor. Should have a push-on type cap.

Timing marks on the flywheel will be the same or similar to this pic, IGN line is 4 BTDC.

On my 300 148 gas engines there are two marks, ING and DC. The (ignition) ING is 4 degrees advance. I would think you can make a chalk line on your first or upper line and it would be what you would use.
 
Thanks for all your help. Got it running today.

My flywheel marks are different, see photo. Took an hour or two of bumping the starter and wrenching the pto before I gave up on any hope of seeing ING etc, Just about 20 lines on flywheel.

So after I cleaned and lubed the advance and replaced low voltage wire from coil to distributor and cleaned connection of this post to high side of points, and replaced plugs I had spark but not start. So after about 5 tries of aligning rotor/distributor/points I had success. Used the middle of all the marks as TDC.

Perhaps because plate on control panel says 440.

Thanks again

I don't know what year range your tractor is, appears to be an early model dry clutch 440 utility with an optional hand clutch & maybe triple range but that is not the timing I am familiar with. Does it have a model/serial nr tag on the dash so we can pin down the year?

That top timing line probably is the maximum advance of the distributor at full load governor rpm which is typically 1750 rpm. Check the model nr on your distributor, the factory IAD 6003 2F distributor stop plate is set for a full advance of 26 degs and starts to advance at 570 rpm on the 148 cid engine. I would sure get a light on it and look at the low end of the timing marks see if you can find an equivalent of IGN or possibly it is timed at full governor rpm like the AC WD-45.

Given your pic, someone here should know how to time this thing. Doesn't your Case manual address timing? Also look in General Specifications section for engine rpm, distributor advance, etc.

I would get rid of that add-on gas filter, most of those things don't do well in gravity systems and tend to starve the carb at some point. Sediment bowls are very efficient full flow if your gas tank is reasonably clean.

Thanks for help, I cleaned fuel tank and bowl, so will remove filter. Shows model 440 and s/n 8244447. Manual is JI general shop manual and adresses ignition timing with IGN mark. But I could not find, so I think each line is 1 degree and gives -10 degrees to +10 degrees.

I ran out of energy today trying muscle pto and look at flywheel for 2 hours.

Was planning to put light on it next time, but not sure about 4 BTDC in manual.

Thanks hose worked well. I brought an inspection scope, but would not fit through spark plug hole. Got running today after lots of try and try again.

Quick way to get to the marks on the flywheel (to mark them in yellow paint pen) was to pull plug in #1 hole and stick long screwdriver in it. Then slowly turn motor until screwdriver starts to go back down. You are at one of the TC's for #1 and your marks should be visible. Go slow on the crank, it will bind the screwdriver if you're not careful.
 
I timed mine and set timing to 4* before TC, as this was a little advance and she was running very well. I have a 148 gas in a 57 310. I have electronic ignition and larger gaps on the plugs but you should see similar, might play with it between 3* and say 7* and see where she runs best. Check for blue snappy spark on pulled plug, if not check primary coil resistance, [b:021bf7b9bd]contact points condition[/b:021bf7b9bd]. The new condensers are poo, I had 2 go bad within a week and so I did electronic ignition (a pain if you don't have to).
 
s/n 8244447 is late 1964 model year. I would bet that it is transitioning into the later 430 series. The older timing marks apparently do not apply. I have very little practical experience in the later 430 series tractors.

Be interesting what you come up with a light. Also your distributor model nr. As far as I can tell from the parts list all the 430 series used the IAD 6003 2F distributor. There appears to be a flywheel change in 1965-66, either that or a part nr change for the same flywheel.

In case you don't already have the 430 series parts list link, (enter 430 in the model search box if the page doesn't load). Covers all the models in the 430 series including the 440 utility. There are 3 separate listings for 430 on that page. Many of the part nrs have changed over the years for the same part.

Did static timing at position shown. I saw a 530 flywheel photo and looked like mine. The attached 1st photo shows The position of the static timing at 1 degree BTDC, which is where the engine finally started and ran. The other photo is more than 15 degrees ATDC.
