i just converted my 2 stroke trailblazer 400 to pre-mix and wanted any accurate input on fuel and air ajustments to the carb. thanks

 

it should be an air screw. i just set it where it runs the best and then screw it in 1/4 turn. thats just me.

 

thanks for the info!

 

I know you didn't ask, but most people premix at 40:1 or 32:1. I do the 40 to 1 on my 400. Thought that info might be helpful now that you converted.

Why did you convert it?

 

ohnet,thanks for your info,its all helpful,i plan on mixing 40:1 but will fine tune it as i go, i converted because my warrantee is expired,and the oil pump failed 2 yrs ago,i dont want to chance it failing again,thanks again!!
