MODIFICATIONS FOR ENGINES WITH COIL IGNITION

IGNITION

Ignition features

Coil-battery ignition with double contact breaker and automatic advance with centrifugal masses. Ignition advance (fixed) 10" Automatic advance FuJI advance (fixed + autom.) Contact breaker gap: 0.35-0.45 mm.

25° ± 2° 35° ± 2"

Maintenance, checking and adjusting the double contact breaker Maintenance

Every 3000 km (2000 miles): • Check contact breaker gap. • Lightly moisten cam felt pad .. A» with a few drops of engine oil.

Inspection

• Remove the double contact breaker cover. after undoing its securing screws. • If contacts are dirty or greasy. clean them

with a petrol soaked rag. If damaged or worn, replace them. • Check contact breakers gap which should be between 0.35-0.45 mm.

Adjusting the contact points

Contact .. 1 .. : left cylinder. Contact .. 2" : right cylinder. • Bring cam ft B" to its maximum lift, loosen screw .. C.. and shift plate .. D» acting on the proper notch. Repeat the same operation for the other contact.

When adjusting the contact pOints it is necessary 2 to check the ignition timing as well.

Checking and adjusting the ignition timing (fixed advance) With the contact breaker gap adjusted at 0.40 mm (0.015) and with the notch .. 0 .. on the contact pOints plate aligned with the mark on the crank­case, the engine is timed : it is advisible to check the timing acting as follows : • To find the exact moment when the points

3 start separating, it is advisable to use an appro­priate timing light to be set up between the brea­ker feeding clamp being checked and the ground.

• Remove the rubber cap which seals the in­spection hole on the R/H side of the gear-box opposite the flywheel.

• Turn the flywheel anticlockwise (engine rota­tion) until the piston is at the end of its com­pression stroke T.D.C. (both valves closed). At this stage mark .. 5 .. on the flywheel should coincide with the mark on the inspection hole.

• Slightly turn the flywheel clockwise and then anticlockwise till mark .. 3 - is perfectly aligned with the mark on inspection hole : at this point (fixed advance) contact pOints of the breaker .. 1-should start to open.

• If this does not occur, it is necessary to sla­cken the two screws .E- fixing the contact plate and shifting the plate same, bearing in mind that shifting in the arrow .. F .. direction ignition is ad­vanced while shifting in the arrow .. G .. direction ignition is delaied.

• Lock screws .. E .. and check the opening of R/H cylinder contact (breaker n. 2) following the procedure of the L/H cylinder. Bear in mind that marks .. D.. and .. 2 .. on the

flywheel indicate respectively T.D.C. position and fixed advance of R/ H cylinder.
