mrtmartinp Posted January 29, 2016 Report Share Posted January 29, 2016 Hi This is an extract from an old copied manual I got a few years ago. looking at the bottom of page 38 though, that's a heck of a gap. Hope it helps though. Paul Quote Link to comment Share on other sites More sharing options...

mrtmartinp Posted January 31, 2016 Report Share Posted January 31, 2016 Hi szymon Just sent them. Still think that's a wide gap, so might be worth getting a second opinion. Paul Quote Link to comment Share on other sites More sharing options...
