  1. '26 disc wheel inner tubes

    The fact is that even independent tyre fitters (you can forget the chains) very rarely handle an inner tube these days. There is also no profit in repairing a tube if they can sell you a new one.! My local outfit are helpful enough when dealing with modern tyres but when it comes to an old car they are just not used to our ways. The practices of old have no place in a commercial facility these days. Even if it is not strictly illegal to replace a valve in an inner tube, the guys doing the work will just say it is so you go away. As to the major proposed changes to the rules by the authorities; we have a last ditch hope of side stepping their worst effects through the efforts of the FBHVC - the Federation of British Historic Vehicle Clubs - who are listened to by the ' All Party Parliamentary Committee" which examines the effects of legislation on our hobby and the businesses which it supports. We are hopeful that sensible exemptions can be agreed. I have spoken recently to the owner of the 'Suffolk Sports Cars Company' who tells me that they (and other producers and kit car firms) are appealing the changes and are quite hopeful of a good result. The replica 1930s Jaguar SS100 they produce is based on the the JAGUAR XJ6 saloon of the 1980s so has a fully refurbished but "old" XK engine which would never pass today's exhaust emissions tests. The cars can be bought ready assembled or in a home build kit form (which I am keen on). I have suggested that if they are unsuccessful in their appeal then perhaps they might like to consider LPG as a fuel not tested for emissions. They had not thought of this and didn't realise that an open loop system could be used with twin carburettors. I think the solutions are usually there if you look for them. Ray.

    Rant as much as you like, Bob. This is my thread and, as you know, I like a diversion now and then. There are a lot of people here who think leaving the E.U. will shake off some of the chains but I'm not so sure. As I write this, our Parliament is carbon copying every single bit of red tape that has ever come out of Brussels and transferring it into British law. We will end up with Brexit In name only. There is even a name for it: "Brexino". We are even adopting the new M.O.T. standards as decided by the E.U. This means that any car over 30 years old will be deemed a VHI (vehicle of historic interest) and will be exempt from the road worthiness test...unless it has been "substantially modified" in the past 30 years...in which case it will have to not only take the test but meet all the latest exhaust emission standards...which, of course, older engines cannot meet. Take a look at some of the brilliant cars which could become extinct.http://www.suffolksportscars.com Ray.

    If you scratch the surface of almost any of the new regulations you will find the letters "E.U." I have no idea whether or not the U.K. will fly or die outside the E.U. but hopefully we will see an end to suffocating legislation. If we don't, then what would have been the point of Brexit? The plan now is to fit a 820 x120 mm beaded edge tube (as shown in the middle photo). I am told this will work. Ray.

    I very much appreciate your help, however BSI recommendations are just guidelines. I think it unlikely that a tyre centre will carry out any repairs that could possibly (however unlikely) result in litigation. They are generally all looking over their shoulders these days. As to your other suggestion. I am sorry but I am not familiar with the software to which I think you are referring. I am probably a dinosaur. Ray.
  5. 26 DB Initial valve clearance set up

    There was no gasket on my engine so I made sure the area was free of oil contamination then stuck A 1/4" strip of cork along the bottom of the valve chest. Being at the front, it holds back any oil that is swilling around on the "lands". Ray.
  6. '26 disc wheel inner tubes

    Therin lies a problem. I understand that this type of repair is illegal in the UK/EU. Even if I was able to get the tubes modified, it would compromise my car insurance... you just can't win these days. Then again, how safe would it be?. Everything is steering me away from tube valve replacement.
  7. '26 disc wheel inner tubes

    So would you glue the valve base (like tinindian has posted) in place of the original rubber valve on the outside of the tube?
  8. '26 disc wheel inner tubes

    I already have a less than perfect option.; I just like to be better safe than sorry. Ray.
  9. '26 disc wheel inner tubes

    Thank you Tinindian. That valve is described for tubeless tires. I don't know if it would be possible to fit to an inner tube.? 27dodger and Keiser. Thanks. I have enquire with various tyre experts over here and despite their best efforts to find a suitable 21" tube of the right diameter they have come up with nothing. 21" Truck tubes appear too big for the DB rim/tyre. I wonder if there are suitable tubes available in the States? Ray
  10. I am having real trouble in obtaining bent valve inner tubes for 400/450 - 21 tyres/tires. The valve needs to be metal as it comes into contact with the rim. It also needs to be bent over - and long enough to exit the disc wheel to the front. (See photos 1 & 3). Trying to inflate the existing tyres (with the valve behind the disc wheel) is a very inconvenient and dirty job. The existing rubber valves on three of the wheels are also chafing on the rim and won't last much longer. In the middle photo (courtesy of Vintage Tyres at the National Motor Museum, Beaulieu) a "beaded edge" tyre inner tube with an angled valve extension is being considered but it is not quite the right size.(More like 22" ). How easy is it for you guys to get the right inner tubes? Ray.

    I would keep the tappets in the same order and position because they will have a corresponding wear pattern relative to the cam lobes. Personally I would junk the old springs; not that you are likely to get valve bounce but so you get as snappier a valve closure as possible. Be careful how you handle the tappets. It is an easy thing for them to drop down into the engine and that would be annoying if you have just fitted up the oil pan.!

    Yes, the groove is worn by the pin under spring pressure. If it's not too bad, the groove can be machined out. Incidentally, all the pins were bent on my engine but new ones are available from Myers. Ray.
  13. 26 DB Initial valve clearance set up

    One thing you might like to attend to is wear to the valve spring keepers caused by the retaining pin. In theory, the valves should be able to rotate on their seats but when the pin wears a groove in the keeper it prevents the valve from turning. Incidentally, this condition can also lead to a tapping sound as the pin jumps in and out of the groove under spring pressure.

    I cannot claim any credit whatsoever as this idea came from an MG expert. Believe me, some of the MG guys over here have mind boggling technical skills not found elsewhere. Ray.

    One way to achieve optimum combustion regardless of which petrol is being used is to set the timing advance relative to exhaust temperature. It is an easy thing to fit a thermometer (or temperature sensor) to the exhaust down pipe and test drive for a couple of miles and record the temperature. Try the same two mile test at the same speed and compare exhaust temperature readings. Eventually by experiment the optimum temperature can be arrived at. Lower exhaust temperatures mean lower under hood temperatures, cooler carburettors, and less vapour lock but more importantly indicates more complete combustion before the exhaust valve opens. Ray.
