RE: blowing fuel out exhaust
Yes my friend...patience is KEY...I can't stress that enough and I HAVE in just about every thread here in the Redcat forums and some several times...LOL!
That is the BIGGEST problem most people have when trying to tune these things...(especially newbies)...they make an adjustment..(usually a BIG one like a 1/4-1/2 half turn or better)...then nothing happens immediately so they keep turning screws and get frustrated... you need to change a little at a time...run it and see what happens....also...do you have a temp gun or anything??.....temperature is key to proper tuning also....these should run anywhere from about 210-240...that is about the best and safest temp range..
Good luck and let us know how it goes![8D]
