Does anyone know if you can use carb internals: chokes, main, and idle jets from a Weber DCOE/Solex PHH side draft carb, onto a 40 mm DHLA Dellorto? I've got Dellorto's on mine, and it needs to be retuned, and Dellorto parts are not as easy to get as the others. Does anyone have some tuning parts they don't need for these? I need 36mm chokes, and I'd have to re-check what my idle and main jets are, but I need richer of both, especially idle jets. I've started to experience a severe lean condition and power loss at 6400 rpm after I match ported my cylinder head/intake and installed dual valve springs. Fuel pump/pressure is NOT the problem as I just put a new high flow electric pump/regulator and it still does it. I believe the carbs need to be re-tuned, but need the parts to do it. Can anyone help???
