I just finished installing a 1275A with Rod Change.
I had removed it as my differential blew a whole out the side with the planetary gears etc.
I replaced the differential with one from a spare engine. Same FD, all complete. I of course replaced gaskets and drive seals and rod seal....all the usual bits.
I got the engine running but noticed that #2 was not firing. Did the usual things like swapping wired and plugs. Still #2.
So I pull the valve cover and go to check valve clearance.....put the car in gear so I can just rotate the hub. NOTHING !
The engine does not turn
Any suggestions as to what I have missed? I'm gutted ( I think is the right Brit term ). I had exhaust, steadies everything buttoned up. Installing twin HS4 carbs with manifold as a set was a feat !
