Hi all, advice sort. I have been looking to buy my 1st ever landy (76 series 3). Having not driven for 20yrs I changed oil and filter fuel and filter and cleaned air filter and re-oiled gearbox and axles and balljoints. The landy runs fine reving the engine (2.25 desiel) in neutral and drives great in low range in all gears over rocks and up hills but in high range it has no power at all once in 2nd and stalls.... any ideas before I put in an offer and buy. Many thanks Anthony
