Hello
I'm having some issues with my carburator, it backfires everytime i let go of the gas. The air/fuel screw has been adjusted to what the manual says it should be and the idle is also okay.
It started happening some time ago and i dont know why it does it. I had it dynoed a few days ago sadly without lambda sensor but it only made 27whp. Which seems to low.
Does anyone know why or have an idea of what it may be.
