Smells like burnt gas,(I would also point out that I had the exhaust sit in viniger for de-rusting. That’s what I think it might be)
Here’s a video of it running

After further inspection I noticed that the left 2 headers were cold while the right 2 weren’t so I think there is a problem with the left two carbs. Probably something like “duh”. The left inner carb should work fine because I never touched it and it worked fine on the bike so what do you think I’m missing??
