I've never ran the stock carb. But general consensus says a stock carb will out perform a Weber off-road. But on hwy, a Weber is awesome. My old 85 Nissan 720 had serious carb issues, and a Weber was the way to go. It gave me almost 30 mph on hwy, and a crap load of power, and I never had issues off road. But I never did any serious stuff. Just fire roads.
There are some people who has ran a Weber effectively on their crawler. Marlin used to run one on his 20/22R hybrid, before he went to a 3RZ. He would switch to the stock carb when he had to smog.
And I deleted your double post.
