Hi Group,

Sorry it's not a car but I thought I'm likely to get the most useful
help here.

I have a lawn tractor with a 14.5hp OHV briggs and trattor engine.

The engine has been difficult to turn over and has been getting
worse. The starter seems to stick when trying to turn the
engine over like it doesn't have the power to get past the compression
stroke.
However now it is smoking a bit so the power is going through it.
I've tried another starter motor and am getting the same sort of
results.

I can turn the engine over by hands on the top cover and it doesn't
seem
too bad.

Any ideas?

Tried a new battery or a jump start?  Look out for trickyness like the 
electrics being 6v.

Failing that check for a bad earth: corroded earth strap or duff 
terminals on the starter and batttery and suchlike.

Bad Earth or  feed from the battery? A high(ish) resistance
connection will drop the voltage across the starter significantly.

Also, perhaps the battery is screwed - have you tried another?

Cheers,

Hi David,

What is smoking?

Apart from the other suggestions, another possibility is a 
knackered starter ring.

The starter appears to start smoking. If I hold the key on to try and
get it to turn over.

I'll try another batter although this one seems to be ok.

Stick a meter across the starter whilst it's cranking.

I would say you have a high resistance within the starter which is causing 
the poor starting effort, and the smoke..

From the OP:

"I've tried another starter motor and am getting the same sort of
results."

Starter motors work in an highly overloaded condition, a continous run
motor with the same power would be about 5-6 times the size/weight,
have fins on the casing and a fan on the end. If it's held on too long
(>10-15sec in 20-30secs) it will smoke even with a low battery. Once
it starts smoking it is dead, it's insulation on the winding that's
burning.

Holding a motor on when stalled is the very best way to kill it. Using
a shot battery, needing an excessively long cranking period is 2nd
best way to kill a starter motor.
