I am trying to narrow down some poor running issues and have the 22mm Jetex in parts. Using the info in Stickys manual I have checked the float valve is sealing correctly and am happy that is ok. Looking through posts on the Jetex the common consensus seems to be to use Dellorto jets in the Jetex and that the float valve on early Jetex's was too long.
My float valve is stamped Jetex and has a red tip, and it 18.3 mm in height, looking around at various sites the equivalent Dellorto needle valve is stated to be in 17.3mm long. Is this difference in height.
- Likely to be down to it being an earlier carb and having a too longer float valve ?
- Dellorto float valves cant be used in a Jetex ?
Does anyone know the correct height for a Float valve in a Jetex ?
