Anyone used a career 707 mk2 ?? What's your views on them ?? iv had 1 for a little while, its got a slow leak from the filling valve. the chap I had it off has had it for about 10 - 12 years, and kept it under his bed unbagged .. and over time when filling up im lead to believe possibly dust?? as got around the inlet valve and its not closing tight hence the reason its leaking. im just not sure whether to to get it in for a service or put it up spares or repairs for either a swap for something else or to sell it. could anyone get me a rough idea in what its worth cheers
