Yea, as Al has stated most do. The secondary issue with these carbs and their short arms is resolution. I don't like throwing analogies out there but imagine at first driving a high power car in the snow with only 1/2" of petal travel. Now take the same situation and give the petal more travel ( throttle curve ) but you now have 6 spikes in power due to low resolution. Now set up that car with 3" of petal travel and an infinitely proportional power delivery. Don't anyone take this as me being irritated because I'm not, simply putting free information out there that took me years to learn. If people choose not to follow the advise then I just move on to helping the next guy. That said, I beleive between the video I posted of my 150cc Extra and the take off scores with my electric pattern airplane that my methods work. I do however find it funny that a couple guys from the AMA forum are questioning this. Perhaps it's because there isn't much of an audience there lately?

Once again, patiently waiting to learn how Franklin sets up his gas engine throttle.
