Hi .New to Forum..Need info regarding Emission control parts on a Lance Milan 150..Will not start in cold weather..Enricher works fine. Tried a new carb with same results..Beginning to think dealer connected vac hoses wrong or a component is defective. Lance Power Sports is no help.I know 1 hose from intake manifold elbow goes to fuel pump with a y going to carb cut valve. Where is the second connection on intake elbow go. presently goes to plastic round component with a second hose coming off and going to a round shot glass size part that has end filed with holes that draw in outside air. Wish i could get pictorial of proper hose routing and source for replacement parts....any ideas
Starts ok at 65F or higher...If motor starts in colder temp it stalls and after many restarts it seem when motor has warmed a bit it will run ruff but eventually smooth out and can obtain 55mph on open road. other thing noticed is idle /fuel adg. screw doesn't seem to produce much of a chnge in RPM. Will try to take pix of mess of vac hoses and submit. NOTE also tried 12v Dc pump with regulator and filter with no change in problem. When cold the enricher valve is retracted and when 12v Dc is applied it extends the proper amount in about 5 minutes. (Note) new carb with new enricher in place presented same problem.
