Hello all, I've completed by fuel system refit for my surplus BMC 1.8 (westerbeke w50). There are new fuel filters, lift pump, rebuild injection pump, new glow plugs, and new injectors (all 4) tighter to spec (12 ft/lbs). Successful bled everthing according to the manual and got her fired up. She runs a bit rougher than normal. I was cautious to try and get the timing lined up. The previous pump was quite advanced, rotated toward the outside of the engine. The injectors were also in rough shape. My pump is the mechanical variant without the torsion bar. I don't have much smoke to speak of, perhaps a tiny amount that may be steam it's humid at 10 degrees today. The issue: However, when running I'll hear a 'Lumpy' or rocky feeling combustion (I believe) it's pretty consistent. I do not believe it was there before. It's more pronounced at lower rpm it increases with rpm until it's not very noticable. I slackened the Union nuts in the fuel lines and was able to make the engine very lumpy all the time on 3 cylinders. So I know all are firing at some point. The first and 4th fuel line sprays everywhere, while 2 and 3 are a little more relaxed at least not misting. I hope this isn't too much info. Basically, I'm looking to see if the timing could be the culprit here? Perhaps too advanced to cover for the older injectors? Perhaps I installed it not advanced enough? Possible bad new injector? Another thing I'm playing with for a future task is perhaps too much back pressure. I have way to much rise ~1.5M (60inches). The lump feeling does seem to coincide with the wet exhaust discharge interval. Perhaps I didn't notice it before? Another, thought I had: I adjusted the valve lash, if I over did it when tightening down could this cause that issue? Though, it ran fine with the previous injection pump. Any insight or thoughts would be much appreciated! Thank you!

Hi, I'm recently bought an 1957 Austin fx3 taxi, I'm located in West Chicago Illinois, USA. I bought the car 2 months ago, was in a heated storage for 20 years without starting the engine. I replaced fuel filter, oil filter, oil and fuel, and bleeding the air from the lines and pump, my question is why I'm getting only fuel coming out from the inlet line on one injector ONLY, and nothing on the other three inlets lines, could be something inside the inyección fuel pump? Or something related with the timing on the pump? Any other advices? Any information will be very helpful, thank you. Car has a BMC 4 cylinder diesel 2.2 bmc
