I have an Agway (MTD) mower with Briggs & Stratton 287707 engine with electric start. I have been having problems starting it recently and to make a long story short I am considering installing a recoil (pull start) start. Can anyone tell me is this possible? What is involved? From the parts diagram I'm guessing I'll ned to purchase the recoil unit (399671) and clutch (390391) is there any thing else? A walk through would be a tremendous help! Thanks in advance.
