Okay, another dumb question from me to the intellect of the board. How steady should my RPMs at idle be? Quick history to my question.
I had a vacuum leak where the carb attaches to the intake manifold. Rather than get just a new gasket, I ordered the indigo PCV kit (as my slash tube was missing and I was blowing whatever was in my crankcase into my cabin ). I thought this would fix two problems at once.
After installing everything, my idle would vary about 200 – 300 rpm. Even after adjusting the idle screw on the carb, I could not get a consistent idle. I was around 600 – 850 rpm. Not rough, but not consistent.
After reading some posts about the PCV kit causing some air/gas mixture problems, I removed it and just replaced my gasket. My idle is much more consistent now, but it will hold at around 600 rpms but occasionally drop every 10 seconds or so to about 450 – 500 rps for just a quick second, then go back up to about 600 RPMs. When I give it gas, no problem.
So I said all that to go back to my original question, should the RPMs at idle be spot on the same…say at 600 RPMs, or is a little fluctuation in the RPMs normal.
Thanks.
