Fox 4.2 runs erratic
I have a Fox 4.2 that runs very erratic since the day I bought it. Just a day ago though I found some posts about the DLE-30 running very erratic as well and it was due to the spark plug. From what it sounds like, I am having the same problem. The midrange will barely tune and the high end, when tune properly will not run very consistantly. The engine had tons of power but I just don't trust it at all. The spark plug that is in it is a NGK BPMR6F. Would anybody know of a better plug then this or a different plug that I can use? At this point I am going to try process of elimination. So, anything is up for grabs.
