Also take care to see that the carburetter is fitted quite horizontally, so that when the car is on level road the carburetter is also quite level and does not slope one way or the other. The level, however, will be lower in the Carburetter owing to the increase of density, but this difference in level is necessary and precludes, as a rule, any modification of the jets. Most of the Carburetters supplied by us are fitted with an open main jet cover Fig. I think that I didn't manage to make it change position so I might be lucky and be able to drive it as it sits just by cleaning out the channels with brakecleaner?? Neither should the needle be forced on to its seating with a screwdriver, but slightly ground by turning round with the fingers. Consequently the following items should be examined:- Loss of efficiency in t he En gi ne : Check the compression and make sure the ignition is properly advanced, as retarded ignition is a very common cause of excessive petrol consumption. Make sure petrol is not leaking anywhere between the Carburetter and the tank.
Air Strangler on Carburetter sticks in a partially closed position : This would restrict the amount of mixture entering the cylinders, and cause loss of, speed.

First of all unscrew the dome air intake or air strangler on the back of the Carburetter, then take out the main jet below, and after this unscrew the main jet cover, when it will be found that by turning this to one side the choke tube will pull out of the Carburetter with the main jet cover. The engine will also run harsh and perhaps a little on the warm side. For this purpose new accelerator pump and operating levers have to be re-produced see photos. I9 , but sometimes in the case of old two-cylinder engines, where the suction stroke occurs at irregular intervals, we fit a dome cap as Fi g.

Now I need to pull the other carb and make sure I didn't make the same mistake twice I think I may have. The petrol pipe should also not touch any parts of the chassis, only where it is necessary, as the constant rubbing against anything hard is liable to wear a hole in the pipe.
This indicates that the petrol is being sucked through the slow-running tube, and if the ignition and valves are in order the engine should start immediately. As soon as the engine is stopped, the suction is released, and this liquid petrol runs back through the Carburetter, giving one the impression of leakage or flooding. The inlet valve guides may be worn and allowing air leakage between the stems and the guides. The O ring Supplied for this purpose in most of the repair kits is a poor fit and doesn't hold the jet correctly. Stop Screw on Throttle Lever impr operly adjusted: Set this screw so that the throttle always returns to the best slow-running position. Does anybody have any thoughts on which one I should use? I've read that stock size should be 27,5? This is effected by placing a muff round the exhaust pipe, from which muff a pipe is taken to the air port on the Carburetter. Any questions or concerns please contact me.
