After lots of research, I just purchased a Tanaka tcb-230sf trimmer. I'm very pleased with it so far, and I'm really glad i got one of the Japanese models instead of the new Chinese ones.
Anyway, it has a non-adjustable carb, which is a bummer, but I'll get over it I guess. My question is, the manual calls for 50:1, but I run 40:1 in everything else I own. Will running 40:1 instead of 50:1 lean out the mix too much since I can't adjust the carb?
I asked the guys at the shop where I bought it and they insisted that increasing the oil will "richen" the mix. They did say that running more oil will make the engine run hotter (right, guys, because it's leaner).
So, that's my question, can I safely run 40:1, or do I need to keep two mix ratios on hand? Also, how would I know if it's rich enough? Would I run it with no head to see if it 4-strokes at WOT?
THANKS!
