Hi all. Need some help here guys. i want to really clean up my carb because i'm not satisfied when i go to workshop to service, they just take it out scrub a little with a 2 inch paint brush n some petrol then blow with air. can i take out the carb n dismantle it piece by piece, clean it n put it back together. will it go out of tune then? Or maybe u guys have a 'step by step' instruction for this? Is there also any gasket or anything that needs to be replace after taking out the carb? thanks all.
