I am to the wiring stage of my scooter project and I've run across a dilema of sorts.....On some wiring schematics there is a resistor, either 5 or 10 ohms, 5 watt, in series with the autochoke coil and on other schematics there is none. Anyone have any input on when a resistor is called for? Thanks in advance for any help you may be able to give.

I really don't know from experience so hopefully someone with experience will pick up and give you a better answere. It would effectively reduce the voltage being applied to the heating coil. That would for sure slow done how fact the auto choke stopped enriching the mixture on a cold start. If you do not get a better answer, I would put it a 10 ohm in and if I then experinced too rich a mixure or to long a rich mixture on cold starts, I would reduce the resisance. to perhaps 5 ohms- 5 watts. If still to rich I would eliminate it. Too low a resistance will also run more current through it and cause it to burn out sooner.

Your answer makes perfect sense since the autochoke is a heating coil of sorts and that would provide some adjustability in the time it takes to close.... Thanks again. |

Most of the newer carbs have a ballast resistor built into the enricher heater coils... here is the resistor you will need if your scooter had an resistor originally Attachments:

I am installing a new carb so I will assume it may already have the ballast resistor installed. Thanks again. |
