Monoblock petrol level
« on: July 09, 2013, 11:40:15 am »
Monoblock carburettor float chamber covers frequently have a dimple in the centre to indicate the petrol level however without x-ray vision this seems of little value. If you remove the covering nut from the idle jet and push on a piece of clear plastic tube the petrol will fill this up to the level in the float chamber. Amal used to supply shims to put under the needle float assembly to raise the level of fuel , if you wish to lower the level a piece of brass can be soldered to the float. Where the needle touches the float must be mirror smooth otherwise a sideways thrust can be imparted onto the needle causing it to stick open. Sorry if I am teaching grandmothers to suck eggs but it might be useful to someone. Graham
