hey guys just a quick question. Today I wasrunning my grp non-tuned out with an ambient temp of about 75 to 80. So I got out and my engine was really rich when I started and assumed it was my engine breaking in a little because its got just around a gallon on it. Then It leaned it until it ran well with a good amount of smoke. I temped it and it was at 225 so I thought it wouldnt hurt to richen the lsn and the hsn just a small turn(about 1/6). I did his and it literally was rich to the point were it bogged and cut out. Are these engines that sensitive or is that not normal?
These engines new to be warm in order to perform. I let mine idle on the box 3-5 min before my qual or main and defiantly make sure to run it 3-5 min on the track before I even try to change the tune. I have a modded tuned .21 so I know mine is more sensitive but it is seriously sensitive. When these engines are cold they will sound so rich like they are going to die and they will. Keep it running and let it warm up, then tune it. Once they warm up they lean out, so if you have it tuned perfect but its cold or not up to running temp when you run your race it will lean out and heat up and bog in performance.
