thanks everybody, looks like I have a few options to go with,
yeah I was thinking that running 30% would make it run hotter which is what I am battling along with tuning problems, seems like when I run the hsn right on the edge of rich it is sluggish till about half speed, by time I get halfway out of range it starts to clear up and wants to take off, if I lean it out it wants to shut off when let off the throttle, there is no in between so I was thinking that the plug I am using wasn't hot enough or maybe it is getting too used, so just getting some ideas on some new plugs to try, thanks to everyone for their input
I am running traxxas 20% with a n3 glow plug, I have heard that traxxas fuel has alot of oil it it and causing the plugs to burn out faster so I think that I will be trying a diff fuel as well..
thanks again[8D]
