sir gee mun lao meri gul, cyl is 40L
a couple of years ago i told him how to go about tuning, so most of the things he does by himself. e.g. plug/mech pt adj., A/F mix. settings etc except valve clearance adj.
about timing, hmm, tukka. a mere fluke can sometime bring u to such accomplishments. btw, got it checked with timing gun, it's in reasonable range.
