Jereme6655 Posted September 26, 2011 Report Share Posted September 26, 2011 have you done a leakdown test after it started revving up high? the ignition should not have anything to do with causing a high rev issue. Quote Link to comment Share on other sites More sharing options...

Jereme6655 Posted September 26, 2011 Report Share Posted September 26, 2011 also do a compression test.....these two tests can tell you alot and whether you need to tear it down or whether you caught it before the top end grenaded itself...
