Default Re: Gas/oil mix ratio

A note to clear some things up-
Too much oil will cause carbon build up fairly quickly IF YOU USE NON-SYNTHETIC OIL.
The directions say 16 or 20 to one as stated above because that would be using automotive 30 wt. from the 60's.... The newer oils are far and away better than anything from even 10 years ago.

40 or 50 to 1 may be to lean even with good synthetic due to horrible loose/uneven tolerances in the wristpin and bottom end.
