Starting troubles/EU-I
For a petrol ICE to 'Start' satisfactorily, it needs to be assured of
the following - in that descending order :
1) Engine in correct tune by way of - i) Distributor 'Dwell Angle' setting,
ii) Ignition Timing, iii) Idling rpm setting AND iv) Correct A/F Mixture
or 'CO' setting as recommended by the OEM.
2) 'Adequate' Fuel Supply to and 'just adequate' from the Carburettor
to the Cylinders. A Blocked Petrol Filter can upset the apple cart. Faults
within the Carb such as a high 'Float-Level' or its other Auxiliaries
Circuits can 'flood' it. On the other hand, fuel lines from Tank to the
Carb/return can get choked with progressive wax deposits in old Cars -
like the Human Heart's. Replacing such Piping with new ones is the only
solution, as they cannot be cleaned satisfactorily.
3) With Ambient Temperatures below 15*C, one may have to take the 'Choke'
to some extent, the first thing in the morning. Please read and follow
your Owners Handbook in this respect.
4) Availability of a healthy Spark 'inside' the Cylinders AND Correct
'Ignition' Timing. Needless to say healthy/correct gap-set Spark Plugs
go a long way on this front - not to mention damaged HT Leads otherwise.
Faulty Ignition Coil or its Ballast Resistor 'by-pass circuit' of the
Starter Solenoid Switch can also compound the problems.
5) Plenty of fresh air - a blocked AC Filter can spoil the show too.
6) Correct/Minimum 'Cranking Speed' - for the lack of which a weak Battery
or a worn-out Starter Motor can be responsible.
7) Upset Valve timing due to a worn out timing belt.
8) Worn out Engine itself - resulting in 'compression ratio' below the
OEM specified ‘Service’ limits. |
