Hi again...
..just a quick (and final for that cooler at least) update
..duly got it back from being welded last night and popped it on, secured all, and fired her up... took all of 3 seconds to get things settled on the choke and look down, by which time it had offloaded about half a gallon of lube all over my mates lovely clean garage floor ... oops !
..took it off and spent the rest of the evening attempting to catch the remaining leaks with some mega tough araldyte compound, but to no avail.. I've replaced my oil pressure switch with a gauge and when it fires up there's around 80psi instantly - and try as I may, I just ended up chasing leaks further and further from the source... so it's a binner - foned my local breaker and he's happy to let me have a rummage round his coolers for something suitable - £20.. cant say fairer than that I suppose.
..so - if you fancy a shot at removing and cleaning that cooler - take my advice and leave the hoses attached at the cooler end... just aint worth the grief
ink:
Cheers
Dano
