Jetex flow rate

[scootersi]

Hello all,

I'm trying to cure a top-end issue on my Sil 200, reamed Jetex & AF Clubman. I've concentrated so far on the fuel system and have done some checks on the flow rate per Sticky's recommendations. I have more the enough fuel though the tap (fast flow) & hose at 600ml per minute.

I then connected the carb with float and needle valve in place and got 165ml in a minute which is understandably a lot less than from the tap alone.

Question is whether any Jetex experts out there think the flow rate through the carb could give me fuel starvation issues and if so has anyone had joy with drilling out the float valve aperture?

Regards,
Simon.

There have been a couple of issues on these carbs and flow rates. I too have a new Jetex and took advice re the spindle binding on the plastic float. The answer is to run a small drill through the float to free up the movement. JOB DONE SO I THOUGHT. I then noticed that the width of the float causes an interference fit around the spindle housing and the body of the carb where the pin pushes through. I sanded down this part of the float which freed it up. Hope this helps. Colin
