stripped and rebuilt pair weber 40,s.Engine runs as though on choke,but isnt.checked all jets but no info on brass floats ie height travel and fuel height.Any offers would be appreciated as i am powder coating black my garage wall!

What is the number after40dcoe on top of carb ? different series had different float hieght . Have an old haynes manual somewhere will try to find it if you can give me series no.

dcoe 34 and dcoe 35

i suppose one rear one front?

Remove carb top , hold top in vertical position with float hinge at top and float holding needle valve shut , measure between float and carb top gap should be 8.5 mm . With float away from needle valve gap should be 15mm all measurements are with top gasket in place and DO NOT allow for thesoldered joint in the floats . Use a piece of dowel the correct dia with grooves cut out to clear the joint so that measurements are taken from the float bodies. If carb still floods needle valve may f be at fault or you may have too much fuel pressure. HTH
