It does still happen from time to time on cars. My first car was a Camero that had had some "work" done to it. I noticed that when it was cold and wet that it would run like crap. I took it to the shop and we found some hose wasn't attached causing carb ice. ashontz wrote: > Just curious, why does this general not happen in cars?

Now that you mention it, I just had my carb off my little old pickup truck and it has a 12-volt honeycomb carb heater on the base. Didn't really occur to me til you just mentioned it. Be interesting to check the Nissan manual and see what triggers the carb heater, or if it's on all the time.

When the switch is on power goes to the plate. Jerry of Ga In a message dated 7/28/2008 5:27:14 P.M.

I haven't studied auto engines lately, but the old guys had a heat riser on the exhaust manifold or between the manifold and the exhaust pipe.? It was either vacuum actuated or with a bi-metal spring.? This valve would send hot exhaust gas either to the intake manifold or to the intake air filter.? Either way, it provided the heat to keep carb ice from forming.

This is some sort of plate under the carb between the carb and the intake manifold. Yeah, actually the heat riser would be the carb heat in a car. I'm not sure what function this other thing plays. Maybe helps vaporize the gas more. Just curious. jaybannist(at)cs.com wrote: > Andy, > > Have you never heard of a heat riser?

Most of those cars have a single carb mounted on a long intake manifold made of steel tubing. There is a heat riser and, on 1968 and later, thermostat regulated intake air heat. When aftermarket air cleaners and mufflers are fitted, these heat features are often removed. That is when they experience carb ice. The stock Corvair had the intake manifolds integral with the head casting, conducting heat to the carb throttle base. VW's converted to dual carbs seem to be immune because short cast aluminum manifolds conduct enough heat. Just curious, why does this general not happen in cars? Is it because the carb is mounted on the warm engine whereas and updraft carb is below the heat? -------- Andy Shontz do not archive CH601XL - Corvair www.mykitlog.com/ashontz Read this topic online here: http://forums.matronics.com/viewtopic.php?p=195405#195405 ________________________________ Message 8 _____________________________________ Time: 10:08:10 PM PST US From: "Jon Croke" Subject: Zenith601-List: photos at Osh of new aircraft Monday's visit to the Zenith Booth at Osh Airventure and Photos of the new aircraft at www.zenair.org Enjoy! do not archive ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith601-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith601-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/zenith601-list Browse Digests http://www.matronics.com/digest/zenith601-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
