Re: mixture

50:1 use a good TCW-3 oil

Re: mixture

Unless you are more adept than I am with carb adjustments (dual carb system, right?), you probably should rule out other probabilities before starting to tinker with settings. See if you can get it running with brand new gas and oil (50:1 oil mix -- don't go lighter on the TCW-3 oil, but too much more will just foul plugs). If you can keep it running reasonably well, let it run for a while and it may clean itself out.

Re: mixture

50/1 is mediam...... NEVER EVER EVER EVER use less then 75/1 some motors say 100/1 but this is when the Motor is work A.O.K and never does it is safer to stay below 75/1 with 100/1 mixture!!!!!<br /><br />-
