This needle moves up and down in a drilling
midway between the two barrels of the carburettor. It is moved by a piston
beside it, connected by a link at the top.The needle is very easily bent, so
disconnect the link before removing either the needle or the piston.Push down
the spring under the ball head of the needle. Lift the head slightly to free
the link. Push the link aside.TC auto oil seals.
Lift the needle out carefully. Unscrew the jet into which it fits using a snug-fitting screwdriver. Check both needle and jet for wear, which would cause erratic running and waste fuel. Signs of wear will show as minute groves in the jet or on the needle or bright spots on the side of the needle. auto oil seals.Replace them if there is the slightest sign of wear, also if the needle is bent.
When replacing the needle, guide it carefully into the jet. Reconnect the link to the top of the piston.Push down the spring and lift the needle to free the link. Carefully lift the needle out. Look for minute grooves or bright spots which indicate wear on the needle.Unscrew the jet with a correct-fitting screwdriver. auto oil seals.Lift out the jet; check it and the needle for wear.The choke setting is adjustable for summer or winter. The adjustment is made by moving a pointer attached to the choke body along a graduated scale. An average setting for all seasons in Britain is one one mark to the right of the centreline. In very cold weather move the pointer further towards ‘R’ (rich) and in hot weather towards ‘L’ (lean). Loosen the three surrounding screws to make the adjustment and retighten them after changing the setting.TC auto oil seals Big price cuts

The float level is not adjustable.As with any carburettor, the various parts are a precision-fit, and care must be taken to handle every part gently.Before finally tightening the screws holding the carburettor top, ensure that the accelerator-pump piston moves freely.TC auto oil seals Big price cuts.
