Hello Tubes

There is no shortage of P2 Villiers on this site.
The caution - I would think - is that this is a Villiers Junior carby
for the G series (70cc), rather than the Midget (98cc) engines.
They look similar but jetting must have been different.

Any help welcome.

Hi Phil
I am no Villiers carby expert.
I wish I had an answer. frown

There is an easy trick I have learnt - provided we have cylinder evidence...
70cc engines have cylinder cooling fins at 90 degree around the spark plug.
98cc engines do not.

Please keep us informed as to progress.
I feel you are assisting folks in a similar situation.

Cheers

Hi All,

With the junior carburettor the jet and centre piece is usually marked with a code. 98cc Midget Mk 2 is usually marked M7J and Mk 3 is usually marked M8J. Atco Villiers normally used the M7J. Not sure if anyone has the manual and parts book for the G series as this should detail the jet and centre piece code.

Cheers,

Sir Chook

Hello Sir Chook
Many thanks for the simple explanation.

Your explanation of the Villiers Junior jetting marks should help many members.
I am always amazed at your specialised knowledge.
