Re: DB18 Torque Values

Brian H : please do not equate modern high tensile wheel bolts with those of a car designed before WW2 . The advice you have given may well be dangerous , because applying torque appropriate to the modern era to an old car will probably stretch the stud , and this leads to unscrewing of the nut(s) a...

Re: V8-250 Saloon: Carb Fuel Pipes

Just as a matter of interest, the flow potential of a pipe at any given pressure varies as the 4th root of its internal diameter , and thus the 5/16 pipe will deliver slightly under 2.5 times the flow of the 1/4 inch pipe, which corresponds more or less exactly with what has been stated above, where...

Re: Basics engine help!

I think you have so grossly enriched the mixture that you would never get a hot start. Take a carb bell off and see where the jet is : if it is significantly more than about 1/16 inch down then you are very rich . try screwing the jets back up to the 3 flats position they occupied and see if you can...

Re: Daimler Carburetors

Gosh, Stan, it IS complicated ! Just one further thought, which may be useless, but I shall give it nonetheless : the description of the carb suggests that while there are 5 or 6 of those vertical tubes in the " tube block " in the main body , not all of them carry fuel by having a jet in them , but...

Re: Daimler Carburetors

Stan : looking again at the carb diagrams, you make no mention about the air valve for the primer. Is it possible that this has become closed off/choked up so that neat fuel is being drawn through the primer ?

Re: Daimler Carburetors

Stan : I have no expertise in these carbs, but I think you are almost certainly right when you suspect a petrol primer defect. The primer is in fact very similar in principle to the electric "starting carburetter" used on SU setups on most Jaguars with a spring loaded needle operated by a small sole...

Re: Going Hybrid

Well, at least with the amount of hydrogen generated the explosion when it comes will just be a small pop

Re: Run Click And Collect

Since you are perfectly entitled to go anywhere in England since the change in regulations 9 days ago , I am pleased to hear that you were not stopped. it seems that someone has taught police to read the Regs in the weeks since this started

Re: SP250 strange braking behaviour

This is almost certainly a. contamination of the discs as already mentioned , e.g. by rust patches on inner or outer surfaces , or b.warping of the discs ( less likely if it has come on during a period of disuse) , or possibly slack in the wheel bearings allowing the disc to run eccentrically ( also...

Re: Clayton Dewandre Servo Specialist

Rolf - is this for a V8 250 ? if so, your best , and cheapest, bet is to fit the uprated servo sold by SNG Barratt
