Hi All, I've covered a small amount of miles since the full engine rebuild, say about 32..was running fine but now on start up from cold, its sound like its running on about 6~7 cylinders. I thinks its the carbs again, last summer while the engine block was away at the engine overhaulers I stripped and replaced all the gaskets, rubbers, 'O' rings ect, didn't change the floats or jets thought, have fitted new needle holders, everything was cleaned & reassembled. If I pull the choke out then it'll stop, no rise in revs at all, could it be the one of the floats are knackared/ punctured ? could the old jets be worn ? Sounds better on higher revs though.
I have to replace the oil pump as fitted an uprated version as I did several yrs ago to my old P6 but on this one I stupidly removed a small amount from the bottom of each new gear & created the smallest amount of end float so once the oil is hot its loses it pressure, there should be no movement at all as its an extremely tight tolerance fit once the oil pump cover is back on so I'll need to replace these and fit correctly without any end float. I may just fit the old gears back in as still have them, the updated version is basically the same with taller gears, same as the SD1 version, the kit provides a same shape spacer which fits to the housing once correctly shimmed, I know the original pumps weren't great but they weren't terrible either, I have fitted a new tadpole style oil pressure relief valve & new spring, So not driving at all at the moment due to this & crap running :-(
