I know this sounds stupid but I do not know what to mix my fuel at, I have seen guys mixing at 50:1 but the gut I just bought it from said 20:1 ?

I mix my Suzuki DT85 at 40:1

Thanks in advance, any help would be apprieciated.

The Merc and the Suzi both do best on 50:1, Dave.

If the Merc has been running 20:1 you should probably do a decarb. Check the Engine FAQs for decarb advice.

Good luck.

Thanks for the quick reply and the decarbing tip.
