Subject: Re: LR125 at Silverstone Auctions on 4/09
Simon hi,
various factors come to mind. We spent an eye watering amount rebuilding the solex (could have bought 3 SU and manifolds for the same sum) and another £1k having them set up right, they are not well known and I suspect real expertise is thin on the ground. But now they are superb and have needed virtually no tuning in 10 years or 10000 miles. Since putting a 4 speed auto in my car, it is quite high geared, meaning 30 mph on the flat may barely be above idling, yet the engine copes very well and I put this down to the flexibility inherent in the twin choke design of the solex. Compare with my other manual car, which granted has high lift cams etc and 3 SU, and it really doesn't like below 1800 to 2000 revs
that said I do know at least 2 cars were specified with SU from new, 118 but it basically had a full DB5 engine with 3, and 152 which only had a pair (and I don't suppose we'll ever know what cam shafts it had)
The solex when it changes from slow running to main jets at about 3000 rpm has quite a dramatic effect on performance, which I suspect the SU setup won't have
horses for courses!
Best wishes
David
