Hi fellow HEF members, I have a British Leyland model 154 20hp tractor we use for all sorts of operations and need some help with it ... so Friday I was brushcutting a fence line at about 75percent power and all of the sudden it started surging the rpm's a couple hundred higher every few seconds or so kinda random... so I cut the power to idle and it sill surges but not as much or as often... anyway limped it back to the shop had it idling for a few minutes and then it just died.
Oil and temp were fairly normal when operating although it was a pretty warm day and temp gauge was a tiny bit higher than usual. I don't put a lot of hours on the tractor so it sits for a while now and then so it's kind of a seasonal use tractor.
After it died I tried to restart and it wouldn't even puff so let it sit a bit worked the throttle and kill levers then tried again cranked a few revolutions then a couple puffs and started right up but still surging... went ahead and shut it down for the night was pretty much done for the day anyways and figured I would check on here for anyone with a similar issue... or hopefully PumpGuy will see this thread and says "Yep... common problem with those CAV pumps... I can fix it right up for ya'"
