The spark seems strong. It seems like the #1 and #4 run when I first start then 1-3 run after its warm. When Im driving at lower rpms it runs on all 4. If I try to accelerate quickly the #4 cuts off, I think its the only one, and itll die if I let the rpms down. After that it gets hard to start. I was thinking the carbs need to be synced. I had the crbs cleaned and they told me it was gunked up, looked like it wasnt cleaned in years. I checked the jets on #4 and they seemed fairly clean and they werent clogged at all.
