Having a no start issue with my JD E100 tractor. Battery fully charged, Briggs an Stratton engine rotates 360 degrees by hand. When I try to start, it will crank engine about one third turn and stop. My thoughts: bad cell n battery, bad starter or drive. Any suggestions? Thanks, guys.

IF you hook up jumpers, or a boost box, does it crank over fine?

I have had two issues like that, the first time the + battery cable was corroded under the connector crimp. Then the solenoid failed from corrosion and pitting. In both cases I could start it by taking a jumper cable from the battery + directly to the starter motor connection.

All connections are clean. Will try jumpers

My were clean as well from what you could see. The corrosion was inside the connector itself where you could not see it.

X2!
I've seen this happen before, but it was on a car.

My Father(r.i.p.), always said, "If your car won't start. Clean your Battery Terminals."
It wasn't always the cure, but it is definitely the best place to START your diagnosis.

So this morning I cleaned wiring connections and hooked up jumper cables to the Corvair. Same result. Starter engages but will not rotate engine. Turns freely by hand.

Do you hook the + jumper lead directly to the connector on the starter motor, bypassing the existing factory wiring.?

Yes. Isolated starter. Direct to ground and + terminal on starter. Same result.Think starter bad fly three years old and garage kept.

It could be the starter, yes - weak.

Here are the starter part numbers from an E100...

I had this issue on my Craftsman "Bob Vila" special. Id have to help the engine past that hard spot (it was compression) and it would fire up. determined it wasnt the starter at all, but the valves were so far out of adjustment (the 21hp V-Twin had 500 hours on it) that the compression was uneven, thus the hard spot.

Adjusted the valves (my neighbor was amazed that I had feeler gauges and knew what they were for) and after that it has started flawlessly for the next 150 hours of use.

That can happen, a lot of those engines have ramps on the cams that let them leak a little at low speed to reduce the compression at stating. You can turn them over by hand because you are turning slow. That being said I have had two starters get weak, one on a 12 hp and one one a Vangard V twin. They were both much older that three years though.

Thanks for the input. I'll post when it's fixed.

As said before, when the valve clearance becomes too great in a Briggs and Stratton engine, the compression release does not work, the engine struggles to turn over despite a good battery and starter.
Adjust the valves is my suggestion, does not cost anything and my experience was embarrassing that I struggled for years with a hard/slow cranking engine, as soon as the valves were adjusted my engine cranks over at normal speed ever since.

More than likely you will need to replace the camshaft. It's a pretty common problem with the Intek engines.

For my parent's machine, we kept putting fresh new batteries in. It helped but never solved the issue on a Husquavara Rider with B&S engine. Later I got a JD L100 from a neighbor with the same engine with the same issues. I eventually decided to replace the camshaft on the JD L100. It took about 3 hours to remove the engine, split the case, swap cams, adjust and re-install. It worked like new afterwards. Then I got the same kit and for the Husquavara and it solved the hard starts on that engine too.

The compression release lever is quite long and I think it wears at the pivot point over time. The one's I removed didn't provide any sort of bump for the valve, so no compression release and had hard starts.

If you look close at the picture, the vertical pin is attached to a sprung counterweight. At low RPM you can see where the top would raise the valve off the cam. Once the engine begins to rev faster, the counterweight rotates that small pin counter clockwise so that the flat section is even with the cam. Over time, that pin starts to flutter around and sprung valve just pushes into that cavity in the cam lobe, rendering the compression release useless.

I took about 3 hours to do the whole job of removing the engine, splitting the case, swapping the cam, reinstalling, adjusting, etc... I think the longest task was cleaning the gasket surfaces. Inexpensive kits are available in the aftermarket, but I still with with B&S parts since the cost was reasonable.

Wow, how many hours were on these engines? If you didn't do the work yourself the shop rates around here would make them junk

As I stated before, this machine is only three seasons old and just used to cut my 1/4 acre property. I just finished adjusting the valves as suggested. Issue still present. Found both valves with loose clearance.going to change out starter. Thanks

If this is still happening after adjusting the valves,
-> "When I try to start, it will crank engine about one third turn and stop."

AND if it is an Intek engine,

Then do yourself a favor and order a new camshaft kit (less than $100). It's not hard to replace at all.

Tony 66. Thank you so much for that U Tube video. I bench tested the starter, adjusted the valves, and finally found out engine would crank fine with spark plug removed. Next step is to locate a camshaft kit.
