Default Modifying a s&s MGL

Got a terrible annoying problem with my carb an "L" mg type.
Runs well at high at hi and low revs but around 3000 it runs like shit.
Will a Thunderjet smooth it out and if so where to mount it.
Remember that it´s a conventional choke-style carb.
Any input is welcome.

Hi Stomper,

Before you start moding this beautiful old carb, check your transition holes, 3 or 4, inside top of carb, betwenn iddle screw and butterfly, are not gunged up... Don't clean with a drill, use stiff britthle from a brush.

Anyone that can play drums with underwear on their head while wearing a monocle is alright in my book...

Here is a GAL I have w/a ThunderJet. I have seen others with them; they were all placed in this position.

Your problem might be in the exhaust area. If your pipes are too big it could cause mid range studders.
thunderjets can help this problem. But on the L carbs there isnt much room for the thunderjet tubes because of the choke flap.
You could cut a notch in the choke flap, or just do away with the choke flap and use the ol trusty "hand over the velocity stak".

hers one with 2. YEAH!!!!!! I had a redneck with a crossbones ask me "what kinda fuel injections is goin on there?"
