IH 130 won't start

57 130 with a 6 volt system. New plugs, points, rotar, condensor has spark but seems weak getting gas and adaquate compression, timing is right. Should this be a negative or positive grounded system? Any 130 information would be appreciated.
 
Buggy: It should be positive ground, but that could have been changed, and if so will work well, if all proper changes were made.

If you think it might be gas related, several things could be wrong. First, most add on inline filters don't work well on graviety systems. You could have a blockage in neck of sediment bowl. There is a screen in elbo going into carb, could be plugged. Your carb might require a rebuild kit.
 
What are the changes that should be made to a negative ground?
The carb. has been rebuilt. I'm thinking of pulling manifold to check for intake blockage. Pulled the valve cover and all valves seem to be working.
 
Make sure that the fuel tank, sediment bowl and fuel line are clean. If you have a in-line fuel filter, get rid of it. You probably need to check the inside of your carburetor. Take it apart, spray all parts in carb cleaner several times, and use lots of compressed air to clean the inside/outside of the carburetor. Make sure the float level is correctly set and install a new carb kit, YT should have the kit you need, but make sure you get the right kit for your carb.

Good luck!

Andy.
 
Make sure that the ignition system is wired correctly for pos or neg ground, here is a link to Bob's wiring diagrams that will help you with the wiring. If the tractor was neg ground and you hooked it up pos ground, it would have blown the coil, so make sure it is wired right and that your coil is still good.

I have it hooked up to a negative ground and it hasn't blown the coil. Not sure if everything else is wired properly. Gas tank sediment bowl and carb cleaned thouroughly. Float is within range.
 
Try a spray of starting fluid into the air intake on the carb and try starting it, it should try to start or run for a couple seconds. If it runs for a couple seconds, it is not getting the gas into the engine and is only running on the starting fluid. Put your hand over the carb air inlet with the engine cranking, there should be good suction there.
 
Plenty of suction at the carb. we tried spraying small amount of gas into each cylindar also.
Spark seems weak with Autolite 386 plugs.
 
Andy: Good point on right carb kit, even though there were only about 10,000 130s built, IH used two different Zenith carbs during the production run. Some parts are the same on both, however the needle valve and seat are different.
 
Are you sure your mag or distributor is in time correctly with No1 piston at TDC on the compression stroke? Remove No1 plug near the radiator and hold your thumb over the plug hole while someone slowly cranks the engine slowly until you feel compression. Then keep cranking
until the piston is at TDC. Your timing marks should be aligned. Your rotor should be pointing
to the No1 plug tower on the cap.

Weak spark could be cause by a weak coil. Hal
 
Buggy,
Ignore the people who obviously didn't read your original post. Weak spark is most likely a weak condenser or coil. Spraying a little gas in the cylinder should give you at least a pop, IF the ignition is doing its thing. If you get a pop or two from gas in cylinder then you have a fuel problem. Are the points gap right ? points clean? How's the coil (6 or 12 volt)?
 
have installed a new coil,the timing is right on,each plug is sparking in sequence but it doesn't seem to be a bright blue spark.I'm thinking I should invest in new wires next.
 
Get someone to help then try this. Remove #1 sparkplug put the wire on it and make sure it is grounded. Now have someone hit the starter with the sw on. With your thumb or finger in the sparkplug hole watch when the spark apears at the plug that should occur when you feel top of compression stroke with your finger in the hole. That will tell you if the rotor is lined up when it fires and your finger feels the push from the compression.You need someone to hit the starter button unless you clamp the sparkplug to the steering shaft. I do this as a quick check when someone tells me the engine wont start. If the plug fires when compression is there it has to be a gas problem.
 
new 6 volt coil with new points and condenser,points gapped at .20 I've tried turning over with 12 volts resulting in very few minor pops
 
That condensor can be bad out of the box, had it happen a few times. Stick you old one back in and see what happens, ALTHOUGH, it does kinda sound like you have the firing order backwards.Maybe switch 3 and 2.
 
Yes, new wires would be a good idea, but make sure you get copper core plug wires, automotive type wires for cars are nothing but trouble on tractors. I've never had much luck with Autolite plugs in my tractors, try Champion D18Y and see if that helps.
 
If the rotor turns CW your need your plug wires in this firing order on the cap and to their respective plug with No1 near the radiator. Hal

Yes it will burn the coil out on a distributor if the battery cables are not hooked up right, I hooked them up wrong before and the coil fried and the postitive cable burned off the terminal on the battery. It has happened to me a couple times before and it will ruin the coil.
 
Then I suspect you have had other problems. Simply hooking up the battery cables backwards will not burn up the coil instantly!!!!!!!!!!!!!!!!!!!!!!!
 
did you adjust the points the correct way? if done wrong, they will be open at all times, just open wider at some intervals.

I give up, you evidentally know more than me, although I have been working on and with tractors, especially Farmalls, longer than you have been alive Andy, so if you say hooking up the battery cables backwards, blows up a coil, then so be it. You are way smarter than I am for such a young man............But when the day comes that you realize that you have other problems that made your coils explode because you hooked up the battery cable backwards, just remember ole John, who will be sitting there saying, I told you so!
 
I never said I knew more about tractors than you, I'm just saying what happened when I had the cables on wrong, again, I never said that I was so much smarter than you are.
 
Im through, you apparently dont know sarcasim when you read/hear it. But I will offer this advice, go out and take a copy of Bobs diagrams and recheck your wiring. If hooking up battery cables backwards blew your coil, then you have a probelm somewhere and it will one day happen again, or you hooked up a 6 volt coil to a 12 volt system. Be careful Andy!
