Engine bogging down and backfiring.
So here is my situation, I tried to fix and start using my buggy again several months ago. The problem I had was a bad cdi. I replaced it, and the engine ran like it was new for probably 25- 30 minutes of riding. The engine then started bogging down under throttle, and backfiring on both acceleration and deceleration. The engine idled fine. I kept trying for 2 weeks, but I eventually got fed up with it, and stored it again.
Earlier this week, I thought I might give it another go. I replaced the carburetor and intake manifold. The engine started fine, and yet again ran flawlessly. I drove it for around 20 minutes, and then it started acting up again. It slowly started bogging down more and more, and also backfiring.
At this point I am very confused, because if it sits for a few months it seems to run fine for a few minutes then start having issues. I find it crazy that it will run perfect, then all of the sudden start acting up. Does anyone have a diagnosis?
Cheers!
