Hi Joel,
Not sure on the Type 3's but on the twin Solex Kombi's the hot idle valve (the one mounted on the throttle body below the carb itself) was installed on Auto's only and opened and extra jet (allowing more fuel in) for a faster idle when cold to prevent stalling, so I guess you can blank it of OK if doesn't stall when cold. Similarly there is an 'idle mixture enrichment' (next to the central idle adjustment) which also increases fuel when cold, and shuts off when heated by a resistor. All the ones I've seen have rattled to pieces and I haven't been albe to find a replacement. I have blanked mine off with no ill effects if the chokes function correctly. I believe they are mostly usefull in very cold climates!
Andy.

Actually, they are there to prevent "run-on" or "dieselling." They simply cut off the idle fuel when the engine is switched off. I had a dead one on a beach buggy many years ago and replaced it with a stock idle jet as a temp fix and the run-on was present, but not too bad - but type 3s tend to run a bit hotter. It's your call.

70AutoStik,
Your thinking about the solenoids on one of the idle jets (one on each carb.), and they are for preventing running on as you say. (And yes, they can be replaced with a standard jet with no ill effect if your engine doesn't run on).
This is different to the hot idle valve installed to the carb's of auto's though.
