My Mk1 Essex is really sluggish on starting. On turning the key the starter motor really labours. On the next attempt it might turn more freely. Often I might attempt 5-10 times and sometime until the battery is drained.
If we leave ignition to one side could it be-
1- I need more power, bigger batteries, although sometimes I double up.
2- I need a new starter motor
3- the turning of the engine has become too difficult
4- something else
Many thanks
