yes they are underneath. I have the same type of carb on my 150 scooter and it runs great. Granted it has good compression and vacuum. The only issues with the is finding the right main jet to give me power yet let the engine run cool enough.

Back to the ninja 250. what is the chance that the low compression would cause it not rev past 5000 RPM? IT just bogs and dies. If I back of the throttle I can usually keep it running.

Thanks
