QJet Questions

[Kilian]

I'm in the middle of a QJet rebuild and have a couple of questions.

The carb that I'm using does not have electric mixture control (blue connector on air horn) but it's missing the black plastic insert that is shown being used in place of the mixture adjusting solenoid. Is this insert needed or something that would have sometimes been left out at the factory? Not sure if the carb has been apart in the past to know if a PO just discarded it.

How do I check the electric choke for proper operation? Can I use a battery charger etc. to apply power and see what it does?

Thanks for the help.

From the sound of it, you have a carb that pre-dates the MC Solenoid. If so, there's no cutout for the solenoid. No insert is missing.

Unless the choke coil is physically damaged or corroded, it's unlikely that it's bad. But yes, you can put 12V to it and watch it move.

Thanks for the reply. My QJet has a hole that the solenoid would have fit into, right now it's just an empty space that is open to the float cavity. Some of the carbs I've seen online have a black plastic cup that fits down into the hole to fill the space.

Does it have a TPS connector? Pictures are easy to post.

A battery is better to test with than a charger.

You need a battery or a 12 volt power supply for testing, not a battery charger. Even a bunch of D cell batteries taped together can give you the 12 volts. A battery charger may work, but the output can spike quite a bit when very lightly loaded.

OK, thanks for the info.

No electrical connectors for the carb. Thanks.
