Kapag naka-neutral sya and I try to rev, parang nag-iistuck up sya at some point. Just upon reaching 1k rpm ayun parang medyo nagstuck sya pero aangat din after.

As for the spark plugs and fuel filter, kakapalit ko pa lang nung January. But I'll have these components inspected tomorrow pagpunta ko kina Speedyfix to be sure.
