Review on Motion Pro 08-0013 Brass Carburetor Adapter: High-Quality 5mm x 0.8mm Adapter for Enhanced Performance by Austin Wolf

First. Description is wrong. All you get is what you see in the pictures. two long adapters and two short adapters with o-rings and nuts. nothing more. While I was hoping for built in limiters, I'm still not disappointed with my purchase. Installation was quick and easy. Loosen the manifold bolts from each bottom carb, carefully insert one (any size, doesn't matter) into the hole, connect your gauge vacuum lines, and you're good to go. The local store wanted $20 for a pair of these, so getting four for half that price is a steal. If you're looking for carburetor timing adapters yourself, get these and 20-25 feet of heavy gauge clear air hose. There are plenty of instructions on the internet for assembling a homemade pressure gauge. I built mine for under $5 so my total investment is in carb sync. <$15. and I will never have to pay a dealer $100 to do it for me ever again.
