2000 F-150 w/ Technocarb Problem

[hsgreer]

I've recently purchased a 2000 Ford F-150 (100K miles) with a fumagated type Technocarb system (bifuel). The problem is when the truck slows down approaching a stop, is sometimes stalls. It runs fine at all speeds and only has this problem when slowing down. As you slow down and if the RPM's drop to around 400 RPM, it seems to get stuck there and then die.

Any help?

Thanks, Steve

possibly needs a low pressure reg, but before you do that have a setup procedure done on it. Technocarb sells a scan/setup tool that most shops should have.
