Is there any difference between a 400 and a 450 carburetor on the inside and how do you tell the difference on the out side i know they have numbers on the out side this is the number i have for the 450 362173r92 not sure on the 400 and the number i have for the 450 I'm not sure? I have a m pulling tractor that i would like to putt a bigger carburetor on it i know the choke is on the in side on these and i was thinking the 450 would be the best one it has a lot of compression and lp manifold and was thinking the 450 carburetor would work the best can't seem to get a enough gas to it. i drilled out the jet on the stock one and the metering stem to.
