The Honda engined machine also had its issues despite bills for over £1100 (yes, you read that right) in the last six months! Problems included collapsed front roller bearings, seized/worn out traction clutch push rod, sticky, incorrectly set up main clutch , four inch crack in the engine platform and strangely enough considering that new cylinder bearings had been fitted, unequal length reaction springs on the cutter unit! All fixable with knowledge, attention to detail and a bit of graft. The collapsed roller bearings were a bit tricky as the outer races were buried deep in the roller end caps and required the old trick of running a bead of weld around the inside of each race which when cooled shrinks and loosens race. A sharp tap and they fell out. Have tried to upload some images but although I succeeded yesterday, today it just sits buffering. The only thing that's changed is an upgrade to iOS8. Hope that it's not that as it will mean a bug fix from Apple!
Going to email the images from the iPad to the PC and see if I can post them from there.
Looks like that has worked!
