Sorry for taking awhile to respond I has to get a Kubota RTV finished so it could be picked up before the storms arrive today.
If memory serves me well that it just as the ACR closes and yes it would more than enough to cause loss of ignition. Be glad it hasn't fired as it would jerk the pull rope out your hand. I had a few Honda's with bad ACRs that actually dislocated a finger or two. Hurts as like heck too.
ACR = Automatic Compression Release
