volume, engine must be cold, piston must be free

of carbon deposits and cylinder head must be lev-

eled.

– Remove both spark plugs and bring one pis-

ton to Top Dead Center a using a TDC gauge

(P/N 414 104 700).

1. Bring piston to TDC

– Obtain a graduated burette (capacity 0 - 50 cc)

and fill with an equal part (50/50) of gasoline and

injection oil.
