Super C wont turn over

Albo5000 · Apr 11, 2011

I just bought a 53 Super C. It was last used two years ago and it will not turn over so far. when I pull the starter lever the engine will crank very slowly. Battery is mostly charged, 6v, 593 cold cranking amps. Also floods carb.

Additionally, when connected to 12v battery via jumper cables tractor cranks a lot harder but will not turn over. When connecting 6v battery with provided cables, cranks slow. When connected to 6v battery via jumpers to the starter, starter winds up like toy motor but will not crank engine.

I am definitely going to rebuild carb but i want to get tractor started first. Also going to replace all the hoses, belts, plugs, wires, distributor, and eventually rewire the entire electrical system.

What should i do to try and get her running? Is it worth it to re-wire as a 12v system?

If cranks, it is turning over. Pull the spark plugs shoot some starting fluid in the cyl. and put the plugs back in(Fast as you can)and try to start in. If it fires then you know it is a fuel problem.

is the started spinning freely with out engageing the flywheel

When it cranks the fan and belts all turn about an 1/8 of a rotation. It cranks about every 8 seconds or so. Tried pulling and cleaning spark plugs and blasting carb cleaner into engine with no luck.

When you say fuel problem....what exactly should i be looking for? Replace with new fuel. Should I be adding lead to the gas? It was built in 53...

Sounds like you have a bad connection. These smaller tractors should wing over pretty quick on 6v. Replace the cables with ZERO gauge cables, and clean all of the ground mounting places with a grinder or sandpaper. Should turn over good as new then. Carbs will drip after cranking over for a bit, just how they are.

are you getting fire to the plugs?? if it spins over real good then you might
not be getting any gas in the cylinders.

I always poor a little oil in the cylinders when i first get a tractor that's been siting. i take the plugs out, pour some oil in and let the engine turn over till its quits spraying oil out of the cylinders, put the plugs back in, make sure I'm getting fire to the plugs and make sure I'm getting a good flow in the carb.

You should start with installing 00 battery cables and don't make them any longer than necessary. Clean all connections until shiny and that includes where your battery is grounded.
If you removed the distributor you need to make sure you have it timed right to No1 piston on the compression stroke. Hal

So I will try to replace the cables. How do I know if it is a distributor or mag?

Also, does anyone know about the Fuel. Should I be buying leaded gas?

El Toro · Apr 12, 2011

A distributor requires battery voltage. The mag doesn't. Hal

Run the ground cable to a starter mounting bolt or a bolt close to it. That short cable by the battery box has too many rusty joints for good contact.

Albo5000 · Apr 12, 2011

And this is definitely a positive ground?

(quoted from post at 05:35:30 04/12/11) And this is definitely a positive ground?

As long as it's 6volt, yes.

Crank and turn over are the same thing. I think you mean it turns over but won't start...
A couple pictures would answer a bunch of the questions you're getting...

When it comes to the flooding whats it doing to make you think that? If you've got gas coming back out of the carb you're seeing a very common problem where the need sticks. Take a 3# hammer and tap the side of the carb, see what that gets you.

Take your multi-meter and see what the voltage out of the battery is. A 6v battery should read 7+ volts. If its less theres your slow crank problem.

Its quite possible somebody has run light gauge battery cables, this is pretty common as a lot of people bump start their tractors and the light cables are fine for lights only. The proper cable is the same around than your thumb (0 or 00, I forget), if its sized more like your car its too small...

Alright, It does crank, does not start. As for the Carb flooding, when i pull back the air intake hose fuel streams out after cranking. (similar to when my friends H wouldnt start)

When the battery was hooked up to a meter it read 6v, needed a slight charge, and was pulling 597 cold cranking amps when the battery says it will do 625. I think regardless of the battery's charge i will replace the cables with 0 or 00 gauge, it is already grounded (to the positive terminal) on one of the starter bolts and the ground near the driver is dis-connected. I will have to try all the suggestions when it stops raining here.

Thank you all for the advice!

Looks like the starter needs work. (new bushings)

No need for leaded gas.

Ludwig · Apr 13, 2011

Yeah tap the carb with a heavy hammer, my Super M does that same thing when its sat for a time with no fuel stabilizer. Even cheap stabilizer fixes that problem.

6v is not a fully charged 6v battery just like a 12v battery isn't fully charged at 12v. In fact most fuel injected gas engines won't run unless the battery is 13v or more.
Put the battery on the charger and read your meter...

Dunno what you're saying with cranking amps, you've got a ballast battery tester?
