im fairly new to carbs. On my 1974 w200 it has a Holley 2 barrel. When it starts up it will idle fine, when I give it throttle it bogs down and tries to die then will rev way up. I had acquired this pickup from my grandpa. He once talked about drilling the jets out to run it on alcohol but not sure if that ever happened. Any help to figure out what I need to do to get rid of the “dead spot” would be greatly appreciated.

TIA, Ethan

It doesn’t seem to get any better/worse when engine gets warmed up. I have been through the carb and everything seems to look okay. How does one check the acceleration pump?

Once the engine is warm nothing seems to be any different. I have been through the carb and all looks good. When I give it throttle I can see the streams of fuel spraying in the carb.

If the stream is steady do you guys think i should still put new jets in? I’ve been through the carb just haven’t put new jets in. Anyone have an idea where I can get jets for that specific carb?

All I had replaced was gaskets..I ordered the wrong kit for the carb. Where and what kit do I need to get if anyone could point me in the right direction to getting one that would be much appreciated

How do I know how much of a steam there should be? Looks pretty decent to me. Engine usually runs for a good 10-20 minutes before I checked it
