Weber swaps are very common and effective with these trucks, typically a 32/36 DFEV or DGEV, plenty of threads about it on this forum.

Just take care you get a genuine Weber made in Spain, as the Chinese clones offered by Empi and others only licensed the branding and general design but aren't finished to the same exacting tolerances, so they can't be tuned to run properly in all conditions. You can spot the clones as they'll have a smooth/bright finish and only a decal, tag, or ink stamp with the Weber branding, whereas the genuine Webers have a rough/dull finish with the Weber name/logo and "Made in Spain" cast right into the body. Also, the electric choke covers are black plastic for cloned units, vs. translucent off-white for genuine units, but these can sometimes be swapped (e.g. to convert an original water choke to electric), so it's not a dead giveaway.
