Machan, recently rebuilt my 110 with the 2.25 petrol engine. Up to around 55mph, it's running nice and smooth way better than before.
But when I go beyond that, like on the highway, the pulling power just drops. Feels like something holding it back.
If I pull the choke out like 10%, then it runs a bit better not perfect, but improves.
Any idea what might be causing this? Could it be fuel-air mix, carb issue, or timing? Anyone had the same problem after rebuild?
