Pete, I'd suggest having your mechanic take apart the carb. This can be done without fairly easily. He then takes it apart and makes sure the vacuum tubes inside the carb are clean. He also removes the mixture control plates and cleans them. As I recall, he then strops them by rubbing them together with an abrasive so they are both very flat and seal well against each other. After assembly, your Stromberg carb will have a very controllable mixture control. It's not that big a deal to do. When mine was done, the billable time was about 1.5 - 2 hours. I've saved many times that cost in fuel over the years since.

I really appreciate your taking the time to respond. Right now every gauge is out of my Coupe and I am getting ready to paint the instrument panel and send the two AH's and altimeter to the shop for calibration.

I was very busy and couldn't answer then. I, also, have had lots of trouble with Topica in the last month or two. Strangely, after I set up Netscape to easily get my mail from my netscape.com e-mail address and subscribed there, my regular address started working find with Topica and hasn't failed me for a couple of weeks. To answer your question about gauges: I don't have a CHT gauge. I do have a sensitive EGT I got from K&S. It's a single probe gauge so I don't get cylinder diagnostic info. I've become convinced that Coupes MUST have the sensitive type of gauge. No matter how carefully I listen, I can't hear a sharp or big change in the sound of the engine when leaning. Nevertheless, I get a very distinct peak and drop as I lean with my Stromburg carb. My Stromburg carb responds slowly so, as I lean, I make small movements and wait 10-30 seconds to see the results. My K &S EGT gauge has 25 degree marks that are about 4 millimeters apart and I can control my EGT to 10 degrees with accuracy. After adjusting it, I turn the knob to put the needle on the special mark so I can easily see deviations as I fly along. The non-sensitive gauges that show you 500 or 800 degrees in one sweep of the dial with no adjustment knob are barely worth bothering with IMHO. As I learned from the book, I lean to 100 degrees rich from peak for max power and 50 degrees rich from peak for level cruise. At altitude, I really can get the fuel burn rates at 100 mph down to the 3.5-4.0 gph the charts say is possible. From Iowa to Connecticut required only two fuel stops (and three on the way back).

I do tend to think something is amiss from the Topica end however. The Coupers are really responsive to a lot of issues on the site, however, when I put out the e mail asking for input regarding the EGT and CHT units currently in use by Coupers, I did not get a single response. This does seem odd, given the responses to many other requests. Either no-one uses a CHT EGT gauge, or they did not get the message. Just seems a little odd to me. I finally got what may work because of Lee at Skyport, even though he does not carry the units, he was able t ========== ==^================================================================ This email was sent to: [EMAIL PROTECTED] EASY UNSUBSCRIBE click here: http://topica.com/u/?aVxiLm.aVzvvT Or send an email to: [EMAIL PROTECTED] T O P I C A -- Register now to manage your mail! http://www.topica.com/partner/tag02/register ==^================================================================
