Quick Fuel Technology 3-206 Non Stick Rebuild Kit for M4165/4175 Style Carburetor

fit perfect

Poor packaging! You will need an X-Acto knife and some patience to scroll around and dig out your gaskets and seals. Haste will make waste. The other problem is that all Spread-bores call for an 8.5 power valve in the front and a 6.5 in the rear. This kit comes with two 6.5 power-valves. Some of their kits come with dual 4.5's. Plan on buying one 8.5 power valve for the primary if you intend on doing the job right.The kit has quality parts, but having to do brain surgery to get your parts without ruining them and buying an additional power valve; not so good.
