Nah, Runs Great! Pulls Hard all the way to 5k...
just sometimes has a lil stumble when your doing 30 behind some a-hole on the highway and you jump on it to pass.
Probably no problem with the carb. You just need to be in the right rpm range when you kick in the secondaries. Since you are running a 4 speed, downshift to a lower gear and wind it up a bit (2,500 to 3,000 rpm) then her it rip when you get your chance.
