Hi, bit long winded but here goes, bought a Mk1 1300xl with a 1600 crossflow, came on twin 40s but running rough so changed to a new 32/36 Weber and ran fine but I had no history on the engine but it had a high pressure oil pump and fuel regulator so I thought the engine may have had some work done. Fast forward 2 years and the head gasket went, took the head off found steel rocker posts, big valve head and +.060 pistons, all seemed fine got the head lightly skimmed and reassembled ( new gaskets and valves ground in) Assuming after all the top end work that there must be a hot cam of some sort fitted but as the engine has not been removed I don't know which one it is. Engine starts and ticks over but falters under acceleration, I have set tappets at .015 both inlet and exhaust as a starting point but unsure as to what the timing should be, going to work on it this weekend, pal has suggested 14 degrees btdc would appreciate any help
Thanks, Jeff
