Okay first of all the manual has conflicting information and should corrected. On page 2 of the manual under specifications #2. It shows ratio of lubricating capacity: 30:1 and on page 4 under maintenance of the engine under #1. I shows the ratio of fuel to oil at 50:1 so my concern is which one is its. Because this section show in proper grammer of the fuel to oil mix of 50:1 and show on line #2. Of this section shows breakin rpm of 4500 at 0.5l of fuel. This is very conflicting and they might have to send me another engine because of it. I broke in the engine running this fuel mixture. And after going online and reading up on alot of other post. They say different. Please have you vendor correct this issue.
