Small Engines (Lawn Mowers, etc.): Mountfield 81303 settings, low speed, airflow


Question
Hi,
I have just restored a Mountfield 81303, it runs a treat although I am having difficulty setting the airflow/idle correctly.
Can you advise on the settings/number of turns out
Regards
Mark

Answer
Hi Mark,

Sorry for the delay.  

The high speed mixture screw is initially set at 1&1/2 turns out.  Then adjust it to give good acceleration and top speed while keeping the screw as far out as possible.  The low speed mixture screw is set at 3/4 turn out, then adjust to give a smooth idle.   

Good Luck.
Michael
