hello folks,<br />my motor has just recently (well, the last two times I had it out) begun to idle worse than usual (actually stalls occasionally now, never did before) and this past time I confirmed that the revs are down 500-1000 at WOT. My thoughts were perhaps I've lost a cylinder or something, or maybe it needs to be decarbed or whatever. Carbs were rebuilt six months ago by a shop, plugs are 3-4 months old and look normal. I am using the same fuel oil mix as always, haven't done anything different to it lately.<br /><br />Oh, and I'll add that in addition to rough idle, it will often stall as I put it into reverse.<br /><br />What would your recommendations of where to start be? I don't have a compression tester. should I just go get one? or is that not the first step? <br /><br />Thanks much guys!
