Hi guys! Lumabas na rin Boxey ko!!! SL 4G33 ;D

The thing is, It seems like there is something wrong with the engine... I mean, it accelerates like a van. A kia pride outruns it on straights(tested with a friend)...

I mean, I've heard hypes about this car so I'm thinking there's just something wrong...

What I've done so far:
Top overhaul
new oil
new sparks
carb has been adjusted
The timing has been.... well, timed.

I've heard many people say, "hey nice box. Matulin yan." and they do know it's an SL...

What do you guys think is/are the problem/s

Thank guys very much :D
