Will not start

[J Strickland]

1951 super A will not start. I have cleaned carb, good fuel flow from gas tank, checked for spark from pulling plugs leaving them hooked to their cables all have spark. It has a distributor and I have set the points to .020. What have I missed? I drove it last year and placed it under the tractor shed. I also drained the gas and put new gas in it. Thanks in advance. James

Needle in seat might be stuck not allowing gas into carb.

Do you have good compression?

 

[J Strickland]

Have not checked it yet.

I get in hurry , I shot some 2 cycle oil in cylinders to up the compression if it was flooded . Double check all the timing , and make sure battery is charged up , could fire outside but not in cylinders if spark weak . Make sure the air doesn’t have mouse nest blocking air supply , some thing’s that come to mind off hand

Try running a jumper wire from battery to coil in case the wire is bad or having a voltage drop. Have had to do that on my C once or twice if it sits a while.

If it's like my Super H, when it sits unstarted 9 or 10 months dry cylinder walls do not allow sufficient compression for it to start.

But squirt of oil into each cylinder before cranking and it will fire right up.

Remove the plugs and squirt some gas in the cyl’s. With a bit of oil. If it starts then u have a carb and gas problem.

try turning the distributor while cranking the motor. sometimes the gears in the distributor wear from lack of lubrication and will get out of time.

Is there a float bowl drain plug? I dont see one in the picture but maybe it is hidden. If there is a drain of some sort open it up. If gas comes out faster than a drip you know it is getting gas to the float bowl. Of the float bowl is dry your problem is somewhere between the float bowl and fuel tank. Post back to us what you found after you have it running.

The choke is the little lever on the right of your carburetor. Usually it is connected to the operator's station with a pull rod. That choke does not look like it has been moved in years. Turn the lever Counterclockwise to the end of that slot. If it starts, move it part way back or it will flood.
Just a guess. Jim

Great observation Jim

If freezing temps, could be ice in air cleaner cup
blocking air flow.

If it ran when he parked it, how would the timing change? Leave the timing alone!

I don't have any helpful advice but it appears to me that IH was getting their carbs from Briggs & Stratton.

 

[Michael Soldan]

That's my vote as well !

I am not seeing any cable or rod linkage going to the choke .
