Hey guys, how come, when an engine is under prolonged load that it requires more fuel / can lean out?
Is it the heat increase? The way the fuel atomises?
I had it where it was tuned, be it on the very edge, but it would cut great for a few cuts, but then after a few minutes cutting a few decent sustained cuts, it would start to bog a bit, then it would be ok again if you let off, then you do another cut it would stumble.
Of course it’s too lean, and it’s an easy tweak of the carb, but I’m curious as to what is actually happening to cause it to happen after a few minutes of run time, rather than, say on the first cut under load.
Thanks!
