I've got a manual coming<br /><br />It's a 2000 <br /><br />model# J6R5IB<br /><br />Serial# GO4880267<br /><br />The man I bought this motor from said he ran it at 50:1. A mechanic I talked to said it was made for 100:1. That sounds way too lean to me and I'm probably not going to do it, but I thought I'd get your opinions.<br /><br />I could also use the spark plug type and gap if anybody has it until I can get my manual. Thanks for the help!
