  1. Yep, never easy. I have always found that a system of mirrors can assist with seeing where you are going ... just kidding!
  2. To update: This turned out to be the accelerator linkage. Some spray lube at the pivot or rotating points removed the noise. Thanks for the help all.
  3. Okay, this is the same as mine where this end of the tube is clear and outside air can be drawn into the alloy tube . This is the same as my manifold where this hole is blind with no effective opening. And this 'opening' '(the hole just below the letter M in the word Workmate)' is where compressed air vents from when I blow compressed air into the alloy tube at the other end of the manifold. This 'opening' is where I have inserted my choke stove tube with the other end attaching to the choke thermostat housing cover. So the system operates by the choke thermostat housing having a slight vacuum that will draw air up the choke stove tube. Outside or external air is drawn in the other end of the alloy tube with that air being heated by the heat of the exhaust passing over/around the alloy tube. The heated air (not exhaust gas) then enters the choke stove pipe. The heated air travels up the choke stove pipe to the choke thermostat housing where the heat causes the bi-metal coil spring to move the choke plate. Thanks all.
  4. Sounds like the issue is whether the alloy tube end (where the choke stove pipe is usually attached) should be blocked. So that the stove pipe is not necesaarily drawing heated air but rather just heat?
  5. My car definitely does not have any restriction or ball sitting in the end of the alloy tube. I know that if I blow compressed air into the alloy tube then it comes out of what now appears to be the heat chamber. Which is where I have the stove pipe inserted. In comparison to your setup, I guess that with my setup it is possible the stove pipe could be hotter (at the choke thermostat) given it has less distance to travel to the choke thermostat.
  6. I believe you are correct but I am sure I can feel suction at the point where tube attaches to the choke thermostat housing cover plate.
  7. Hmmmm if I disconnect the tube on my engine then the choke thermostat housing is definitely pulling a vacuum through the tube attachment, so it appears that when the tube is attached then it will be pulling hot air. My choke thermostat housing cover is metal.
  8. Just for info, how hard are those tubes to pull if they were to be replaced?
  9. Thanks all. I will not bother as there is nothing horrendous.
  10. I will pull it off after a drive and see if there is any soot as that should indicate if it is pulling exhaust. Thanks
  11. After thoughts on adding seafoam to the oil of the 56 in order to clean the engine internals. Seen others do this to clean lifters to stop them ticking for example. But these have been modern engines. Anyone done this and any dangers? Thanks, Drew.
  12. FYI after some investigation I have found that the other side, of the tube sitting out at the rear of the exhaust manifold, is actually the hole in the centre of the manifold that faces the engine block (see arrow in photo within previous post above). I have now bent my existing tubing to run from this hole up to the choke thermostat housing. Appears to operate the choke thermostat but the tube certainly gets hot. Is there a danger of overheating the carburettor with these thermostat tubes?
  13. Thanks. All good and working with the old accelerator pump. Check ball definitely in there. Two nice streams of fuel now and car starts on first crank.
  14. Okay great. Thanks all. I have located the tube sticking out of the manifold. The existing tube was clearly in the wrong spot.
  15. Hi John, when you say 'back side' do you mean where the arrow is on the attached photo? The arrow shows the location of a port or hole where the hole opening faces the engine. Thanks
