Just started mine today after 8 months of it in the garage.

1.FRESH OIL
2.NEW OIL FILTER
3.NEW FUEL FILTER.

Check trye pressures.2 of mine had lost 15 psi.

After changing them items,i started it up and left it running for half an hour to check if any seal/gaskets had perished and anything leaking.

Just my starter motor that was f*ked.Don,t know why.

No problems with petrol for me.Was nearly empty so just stuck a fiver in it.
