Slow Starting
My car has had new battery, cables, new cut-off switch but when trying to start the car its turns over too slowly to catch.
Im going to dismantle the starter and check that over today, but is there anything else I could be checking?

I guess you have checked the battery. I recently had a similar situation which turned out to be an old battery (charged OK, just didn't have
the wellie). New battery and car starts on the button again.

Put a jump lead direct from battery neg to engine block to make sure you have a really good earth . Maybe poor battery or timing too advanced?

Not enough cranking amps?

Find someone with an inductive ammeter and measure the current needed to crank the engine, faulty starters tend to need higher amperage

If the battery is ok the usual cause is too much ignition advance at cranking rpm.
Before doing any more parts swapping you need to do a cranking voltage test, ie. measure the battery when the engine is turning over.
There can other causes, worn crankshaft thrust washers are a common cause especially on engines with timing chains.
A knackered starter can cause it also usually because carbon dust in the starter is causing a short circuit load within the starter or on older
inertia starters the shaft is bent.
I would recommend you buy a decent digital multi meter that can measure starter current I use Uni-t UT203 it cost led than £30 from eBay.

Easiest way to check if your battery is shagged, is to have another vehicle running with jump leads to your battery
If you car spins over and is fine, your battery is duff, if it doesn't, you have a wiring or earthing problem
Thats was probably spelt wrong, or had some grammer, that the "grammer police have to have a moan at

Thanks all.
Stripped the starter down and cleaned it up. Bushes has a little surface corrosion from sitting for so long so cleaned those up. Then cleaned out the
horrid old grease that has gone hard and replaced it with fresh.
Starts on the button now  I can now drive the car in and out of the garage. Happy Days
Nice recommendation on the Uni-t UT203 I'll be investing in one of those come payday Alway thought DC clamp meters were mega bucks.
I have quick release clamps on my battery so cant use jump leads direct to the battery, have to use the starter or master cut off switch, think an
Anderson Jack is on the shopping list too.
