I need to rebuild the carbs on my 1999 Challenger 1800 but I'm having trouble finding out what model number carbs I have. I couldn't find a manual on here for a 99, so I have one for a 98 and it says BN-40i-38. SBT's website say's it has a SBN series. I am wanting to find genuine Mukuni rebuild parts, where is a good place to get them and what all should I need. The boat has always been in fresh water and looks to have no corrosion in the carbs. Also, what if any special tools do I need to rebuild them? Thanks a ton!!
