reving problem
Hello
I have just fitted a Range Rover 3.5 on Strombergs to my Landrover and have just started it for the first time yesterday.
On choke when it's cold it runs absolutely fine, and once it reached normal temperature I checked the timing and balanced the carbs and set the mixture by lifting the piston and adjusting through the top until no speed difference was heard.The tickover is not too bad now, but if I try to rev it at all it just drops down and cuts out.
I have noticed though, if I pull the choke out no more than an inch or so, it revs freely throughout the range.
Any ideas please before I start messing with my original settings.
Thankyou.
Graham.

Hi and welcome,
sounds to me as if its too lean mate, and pulling the choke allows more fuel thus being able to rev again,
have you checked the CO out of the exhaust?

The rubber diaphrams do perish and would give exactly the problem you describe. Had this on my late Fathers Sd1 and the difference when the new rubbers were fitted was tremendous. They are only a few quid too.
There is an excellent book on the market (try Ebay) called SU Carburettors and fuel pumps. Its a blue book and gives details on rebuilding carbs etc and also suitable applications for aforementioned swops. Check out this link:

Be aware that HIF Carbs are very problematic with sticking needle valves. Again easily rectified with a kit from someone like Burlen fuel systems.
