Nightrock had his pajero re-painted by that shop in calamba. I'm sure meron din magaling dyan sa Binan...that town use to be haven for local built jeepneys...marami pang magaling na latero, pintor and mechanic dyan palagay ko.
considering that your car is 20 years old na, baka may diprensya na nga ang jets or needle ng carb mo. Maybe what you should try muna honda, baka meron silang repair kit for that carb of your prelude.
kung DIYer ka naman, I'd suggest that you get yourself a repair manual for your ride...available on the net...usually around US$10-25 lang.
The most difficult part to get in a carburator repair kit is usually the rubber boots (parang maliit na motorcycle shocks cover na rubber).
All the rest could be recycled - bearing, jets, needle, springs, etc. - yung gasket pedeng i-DIY. Yung needle (the one you turn to adjust the air feed could be sanded para mawala ang "leeg" due to wear-&-tear.
Mahirap magkalas-balik ng carburator pero it's a thrill (for me...DIYer kasi ako).
The most important part points are:
1) don't overtighten the bolts when you put it back
2) replace all gasket
3) use a "shellac" to seal the gasket sa manifold and throttle body ng carb - (not doing this would make the car like sinisinok due to a vacuum leak).
