Does the 261C with 6 degrees of overlap, per engbldr spec, cause a lean fire condition?
I believe my newly rebuilt 22RE is running a lean mixture (based on spark plug readings)
andykrow's newly rebuilt 22RE is running a lean mixture (high NOx per emissions test)
Years back, when a guy who was seriously testing cam profiles for is 22RE reported that the 261C "caused a lean fire condition".
This may be coincidence, have nothing to do with the cam profile, or caused by one or more conditions or components.
I'm considering removing the 261C, and install the stock camshaft to simply eliminate the camshaft potentially causing the lean mixture I believe I'm experiencing.
