With undiluted oil down to -10°F and diluted oil below this temperature the present motor should be satisfactory down to -30°F.{Mr Friese} Should it be considered necessary to operate down to -30°F with undiluted oil a modified starter will be required. Suggestion is a Simms B5612 type starter (12V) fitted with a reduction | ||
