Hamiltonbobs Premium Quality Electronic Ignition Made for IH International.

Just finished installing this kit on my late 60's IH 504. Overall took about 30 minutes to install the kit. You do need end wrenches, screwdriver and electrical cutter, stripper, crimper. As you read on will likely also need timing adjust wrench. Thought about changing to electronic ignition about 1 year ago, but it was cost prohibitive. This looks to be a new kit at the right price. Well worth the money. You will want to be a bit mechanically savvy. The piece that fits on the rotor shaft was a bit tight and I had to shave it with a dremmel tool a little to make it fit. If not seated all the way, the sensor doesn't pick up to trigger a spark. After installing, the timing had to be adjusted. Had to advance the timing about 1/8th turn. Had to adjust it to get the tractor running and adjust again after warmed up. I then had to re-adjust my carburetor both the main jet and the idle port. Once all adjusted correctly, it now runs great. Glad to not have to deal with points and condenser any longer. I would have given a 5 but I didn't have to modify a bit, so giving a 4. If you are burning oil like mine, get some spark plug adapters (didn't find any on amazon) and then you can put modern plugs that have multiple probes and ceramic coated electrode to keep them from fouling out. I also bought new plug wires set from Amazon that connect at an angle rather than straight as the spark plug adapters made them stick out further causing the straight plug wires to touch the air filter housing. I expect to not have any further ignition issues going forward.

Not that hard to install works great tractor starts Every time runs better add's power highly recommend for your small tractor.

Worked great once I got it attached and installed. Wish it came with mounting screw had so search for the old screws from the points.

Easy install, the 1955 IH 300 Utility starts easier, no more misfires, burnt points, and tiny screws to mess with in the cold and snow. Highly recommend.

The part does not fit my application but says it does fit on the link. I need to return it! I also received three orders of same thing but only needed 1
