I think it won’t be difficult for Tone to find a correct spring because he already did this with his propane mixer see [Gas “carbourator”](https://forum.driveonwood.com/t/gas-carbourator/5133).  
My question is about the mass of the conical element. If there is a bump in the road will the conical element move and create a bad mixture? Perhaps we should make a very low mass conical element out of thin aluminum?
