  1. Lambda sensors can also cause a missfire, particularly if the car is only used for short runs and the engine doesn't warm through thoroughly. The plugs can get wet with petrol. Soot builds up on the sensor. A good thrashing in an intermediate gear will often clean the sensor and dry the plugs and so cure the missfire.
  2. Last time they resurfaced the towpath in B. Stortford they used I think Granite chips onto tarmac, sprinkling them all over the place, and didn't roll them in properly ,if at all, more than half ended up in the river.
  3. Any good 'trade' motor factors would sort that for you. Or online, ''In-line filters'' just put the details in their search, or phone them. Dolomite Sprint and TR7 would be the same engine. The Acclaim is a Japanese 1300cc Honda design engine.
  4. Maybe the Hurricane is though, having the same engine.
  5. A large proportion of the cost is probably down to time wasted whilst the workers are messing about on Facebook. I had an enormous surprise last week when I discovered my old secondary school's website. I posted some stuff about school dinners, how I dreaded sport and described the various administrations of punishments, which raised a laugh. What I didn't know was that the website used Facebook and that I needed to sign up on the dreaded site to get full advantage of the school website and so I did and began having a little wander around it, checking to see if any of my friends and relations use it and wow!!! To my surprise they nearly all did ''Big time''. But the biggest eye opener was the fact that most were on and off it continually almost 24/7, and talk a load of drivel. The list of your friends on the right tells you when they were last on I believe and the rate was roughly 2mins ago, 30mins ago, 7mins ago, 1hr ago, 18mins ago ect, ect, ect. Absolutely amazing when most of them are supposed to be at work. I'm only glad that I'm not their employer. No wonder we're struggling to break out of the recession with all this carry on and wasted time. Must go folks, to get back on Facebook, I'm hooked, like ------ am I.
  6. Proper log burners are unsuitable in boats, especially narrow boats They are very long in depth and would need to be fitted sideways to avoid having to jump over them. They have no grate-firebars and burn the logs on the flat bottom plate. They are purely functional and so are usually ugly. A multi-fuel stove is the way to go, although not as efficient in heat output burning wood as the proper log burner.
  7. The thin stainless flue will not last long unless vigorous sweeping is avoided. Let a skin of hard, dead sooty clag build up in it, this will help prevent the acids and corrosive chemicals in the fuel from attacking the metal. Then sweep lightly in future trying to leave a thinnish layer of clag behind. It should last a good few years then.
  8. It's good. Its when there isn't any weed growth you need to worry which means the blacking's worn off.
  9. Well, the nearest they got to an electronic rev limiter was in the 1960's, a rotor arm with spring loaded HT centrifugal contact which retracted at a certain revs and cut the ignition spark to the plugs, Jaguar E type, Mk11 3,4, 3.8, 4.2 S types, plus others, I recall to mind.
  10. Could be idle speed too slow, or resistance on the prop shaft, over propped or nackered batteries causing the alternator to work overtime.
  11. Have you tried cleaning and probing the pilot and main gas jets?
  12. My first car, a 'Rosemary' a 1936 Ford 8 Y type would bounce valves at about 3,500 RPM, hold all the valves open and the engine would cut out and chime back in when the revs dropped, I regularly did this in second gear. Most old S/V engines had soft-weak valve springs especially the old S/V Ford engines including the 1172cc E93A and 100E's all had very soft valves springs, probably on purpose to act as governors to prevent over revving.
  13. Probably the expansion and retraction coupled with continually being worked of the metal during continual heating and cooling gradually altering the molecules, Though oil pressure relief valve springs or indeed the calorifier PRV springs are only quite gently worked compared to the fast hammering of engine valve springs.
  14. Or by moving the mast or a deep keel backwards or forwards to balance the mast-keel-rudder ratio. Small amounts of imbalance can be corrected by just raking the mast forwards or backward a bit,(tuning).
  15. They certainly can seem to shorten over a long period of heating as can oil pressure relief valve springs.
  16. Due to the springs gradually over time getting annealed and softened by engine heat.
  17. Negative helm on a motorboat is a bit similar to that on a sailing boat. The rudder- tiller direction force is unpredictable and will push and pull on your arm one way or another all the time which makes it very uncomfortable and difficult trying to steer straight, as you say, let go the tiller and the boat immediately dives round to left or right.
  18. Never noticed it with them, probably because I was weakening with age at the same time.
  19. Lea or negative helm is when the tiller is pushing against you all the time, particularly when sailing upwind. It's called lea helm because the rudder is being forced over to lea-ward or loo-ard ie down wind side of the boat which gunwale is lower when healing to to the wind (dangerous). Weather or positive helm is when the tiller is gently trying to pull away from you and the rudder is trying to turn towards the weather or into the wind side of the boat, the high gunwale side, (correct and not dangerous).
  20. To be honest I can't remember suspension torsion bars ever weakening ie Morris Minor, old early 1950's MO Morris Oxfords, certain Mitsubishi's, E type Jaguar ect, though they are-were adjustable for ride height.
  21. Negative or lea-helm is particularly highly dangerous in a sailing boat too. Let go the helm for any reason and the boat will swing off down wind out of control, whereas with proper positive weather helm, let go the tiller and the boat rounds up and luffs head to wind, sails stall, boat stops and all is calm.
  22. The letting down of tyres should be made compulsory before cyclists enter upon towpaths, especially those horrid mountain bikes with 701 gears whose riders resemble huge and terrifying flying insects what with their skinny legs whirling round clad in Eval Kaneval licra suits emblazoned with go faster flames and stripes and wearing weird streamlined crash helmets and blue or orange coloured chrome wrap around sunglasses. They do look a sight which could easily give young children horrific nightmares or even daymares in serious cases. Special posts should be erected with a nail dangled on a string at every towpath entry point which should be used to poke the tyre valves to let all the wind out. A sentry box could be erected there too containing a big ugly bloke brandishing a pickaxe to enforce the law.
  23. I don't think I've worked on a boat that hasn't had some rust in the engine bay, especially cruiser stern boats. Most boat builders, even the so called bespoke brigade too it seems don't bother much about preparing the area properly before painting and usually just slap red oxide straight over light rust and dirt and one coat of bilge paint on top of that which usually only holds down the rust for a few months or so.
  24. I bought my Wanner in 1964 and it's still going strong after greasing literally thousands of nipples. For example the old Fords E93A, 7W, Y type, E83W ect, ect, ect had near enough 30 grease nipples on em. If you take a nipple to the shop and try snapping it into a new Wanner grease gun type claw collet you will need pliers to pull it out again and the shopkeeper may object if you don't go ahead and buy it.
  25. If it did go in healed the problem would be keeping it healed whilst in the lock. Half a ton of cannon balls moved about might do it.
