If you're going to get shot then just go to a scrappy and get a battery around 700 cca. If you're keeping then 1000 cca better. The Optimax batteries are very good or you can get cheaper on the batterymegastore. Think someone on here recently fitted an MF31?

Oh Mozz, get the cam out and work a thin brazing rod up the hole, ( I'm talking oil way by the way). You could always try carb cleaner with a thin tube (as fitted to WD40) then high pressure air line. Get it sorted then it's a keeper because you have to get your use out of it, you'll never get what you spent on it back. Wish you were closer, and I was in the country longer. Still waiting for your call, probably munching cake.

The blockage should be fairly easy to clear it is where the debris goes to when cleared that is the problem. It may self disperse with a bit of luck. I have explained this to you.
