What is the minimum needed for cub to run?

Postby Brandon966 » Fri Apr 01, 2022 6:40 am

Referencing my "too rough" cub project, I was able to get the head off without breaking any bolts, and got the engine un stuck pretty easily. During this process I have decided that this particular cub is just too far gone for my skill set and its probably better left to someone else who has more time than I do.

That being said, I'm going to reassemble it to list, but if simple enough I wouldn't mind seeing if it would run. I do not have a battery but do have a hand crank, I'm assuming the only thing needed to potentially get this to fire off would be for the generator to work...or does it absolutely have to have a battery?

I'm sure it wont be that simple, but considering how easily the head bolts came out maybe there is a little bit of luck left in it.

From the pictures in your other thread, it looks like there is a coil on a distributer. It will need a battery or just a jump box to power the ignition.

A 12V battery or jump box would work for a short time. The coil won't like the 12V for long. I really have no idea how long the coil will last.

Before you try to run it, what do the cylinders look like? Are they rusty, scored, or is there much of a ridge at the top of the bore? You'll also need to replace the head gasket as well.
If the cylinders are rusty, you won't want to run it without removing the rust by honing out the cylinders.

What Paul said and you won’t need the generator working to run.

There have been many cubs that cast far less of a shadow than yours that people got running.
When you only have 9 horsepower you need to know the names of all of the ponies!

Battery charger or jumper cables to power the ignition system.

Opinion. I wouldn't try to start the tractor if you are going to sell it. Oil the cylinders, oil the valve stems and make sure all valves are working, set the head and hood in place. Place ad in Face Book or Craigs List with a link to your posts on this site.

I would prime the oil pump and make sure that oil is flowing into the oil filter housing.
I have an excuse. CRS.

The minimum does not mean greater wear or potential damage will be avoided.

You'll need those head bolts torqued right , AFTER adding sealant to the right areas of them to avoid coolant leaks , and the head properly gasketed. With retorquing to follow if run awhile.

Removing carbon deposits on valves and cylinder tops (as mentioned) might be an important consideration. Valves at least need to move full span and seat properly.

A thorough check of carburetor for being clean and fuel system , with use of a "proper" pony tank a substitute for cleaning the tank and line.

Priming oil galleries as mentioned. And after the mentioned check of cylinder walls, some oil added to keep compression upped if possible and reduced rings screeching. (Not plug fouling amounts though when you're going to try to start it). You can turn it (after priming) without plugs in to give excess one avenue of escape. Though plenty will remain if over done.

Check of air intake system and oil in cleaner. No sense sucking garbage /debris into your carb..

Ignition. Points dressed and checked for proper gap. Plugs gapped right and not fouled. Plug wires not shorting out.
Clean contacts for coil and distributor tower pylons and rotor and condenser , with condenser isolated properly to keep from grounding itself.

Kill switch working right. Or keyed or toggled ignition switch if so equipped.

Be sure fan is oiled.

If you're going to sell it why not have a good battery with it? More so if you're going to get it running to sell as a runner.
And if it's going to run...Why not keep it? L.o.l..

I think you all scared Brandon966 away!

Brandon966,

The minimum you need is the engine back together as it should be, then you need air, fuel, compression, and spark.
