OK, another "ambiguous" bite....
Specific gravity of....
40:1 is .863
50:1 is .812
Which one's richer?:greenchainsaw:

OK, I'll bite....
40:1 has 3.2 oz oil
50:1 has 2.6 oz oil.
Uhhhh, which one's richer.
Depends if you think more oil or more fuel is richer. There are good arguements for both.

Me too... I look at it from a hot rodder point of view more fuel = richer. So more oil in the fule makes a leaner fuel charge. But some will agrue different.
Gary
no disrespect intended and correct me if i'm wrong, but i recently did alot of reading that suggested 40:1 was a leaner mix than 50:1. reason being you have less parts of gas per 1 part of oil than you do at 50:1.
After having to install new fuel lines in my Husky 371 3 times in 3 years because the tygon line shrinks and the mix leaks out of the tank I switched to 110 leaded because it is the only fuel around here that doesn't have governmenthanol. I have used it for 2 years now a haven't had an issue. I mix it a 40:1 with Klotz R50 and have been happy.
What? You guys mix oil into the fuel? There is a seperate tank for oil on my saw...
Gary
yeah i never stopped to think it could be looked at as more oil = richer
Like others have posted ,I think the 50:1 comes from government standrds.
You were right the first time. Rich vs. lean are terms normally used for fuel to air mix ratio's, not fuel to oil mix ratios. Adding more oil doesnt richen the fuel mix, it just lubricates it.
yeah i'm not disagreeing with that, i just meant i never thought that some could be in our discussion and using the terms differently than me.
Yeah, I always think of rich vs. lean as air/fuel ratio.
Adding a little more or less oil to the "fuel" side should not change the A/F ratio much, since oil is technically a fuel, as well, with some BTU's in it ... my cents. Let the carb sort it out!
