Please tell us a bit more; has it got four good compressions? Has it got the correct late high compression head? How do you know the timing is right? The ideal SU for easy fitting is the early Morris Minor type (around 1930) which has a fixing flange much the same as the 26VA, but there are also plenty of slightly later ones with vertical fixing holes, but an adaptor plate made from aluminium is easy to devise. When using an old SU make sure it is clean, particularly the dashpot/piston system, and you will have to find the right needle. The later postwar SUs need more work to fit because they rarely have a horizontal body.
