Just curious why you would block off the oil metering holes.. ?
Hi I think its when people are running premix from the tank.
Think its safer omp can always fail, as a matter a fact mine keeps showing issues on my PFC with it being out of range so I run premix just in case.
but im sure someone else in the know will give a give more info.
