Re: 1965 Datsun engined Imp. The Smurf murder house...

The pivot bushes on the low pivot arms are fractionally longer and larger and the low pivot arms are 1/2" shorter than the high pivot. The change was made because the pivot point of the arms were 1/2" further outward in the low pivot model. I believe that this change was made to alter the bump steer...

Re: Twin Dellorto Dilemma: flat spot

Just a little anecdote - when I was young and stupid (as distinct from now, where I am old and stupid) a mate bought a second hand MGB. The previous owner(s) must have thought themselves tuning experts and left their mark on the original SU's. As a result the vehicle would not hold a tune from one d...

Blue smoke on start is generally an indication of worn valve stem seals. As Sport Heads do not use valve stem seals you don't really have a problem. As indicated above may possible valve guides with a little wear - drive on! In regard to your throttle spring pressure - I presume the pic is with clos...

Re: 64 Mk1 Imp in Wellington NZ

As indicated compression tests are done with wide open throttle. Regardless of that, your results are worrying - IMHO, No 3 is acceptable being only 2lb down (within 10%) but you certainly have a problem with No 4. The only way that it could be a timing problem is if the cam lobes on No 4 are worn (...

35HP? Could it be 35 rear wheel horsepower? I cant remember the maths to convert it to flywheel horsepower but I am thinking this (35rwhp) would be about right.

Still Off topic. In regard to webers off Alfa's - Australia has had emission laws (and other vehicle safety laws) since around 1968 and for many years was out of step with the majority of the rest of the world in this regard. I have posted about this elsewhere on the forum. Around '74 we saw the int...

Your erratic idle is a mystery - it may be once you get it in a good tune the strange idle will disappear.

I have now read all your posts and see that you are running 38's and from memory they may have come off a race car and I think would be pre emission carbs.

Are you using emission or non emission type webers? Non emission type can be identified by the spring under the idle mixture screw. On emission types the mixture screw is in the same place but sits in part of the casting. Emission types have less progression holes. Are they off an Alfa? Alfa types a...

Here in Oz all our Imps are high pivot with the exception of the GT's (Sport in UK).
