JB Weld should conduct temperature well with all the metal it has in it.

What do you guys think?

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

No. Use Arctic Silver Alumina Thermal Adhesive.

BTW, it also tastes great on toast

Which rtvs are sensor safe?

I have use JB weld on two of my engines and i works just fine. The Arctic Silver Thermal Adhesive is probably better and will give you a bit quicker thermal response but JB Weld contains metal which conducts heat pretty well.

Either way, make sure that the sensor tip is in contact with the head and not just sitting in the middle of the glue.

I'd like to hear from anyone who is using carbsmart successfully.
Mine just doesn't work right. It keeps thinking the engine is too hot and tries to richen the mixture. If I let it richen the mixture the engine has no power. Yes it is configured correctly. It just thinks the engine is too hot. If I set the temperature to the highest it works, but this is not right. I don't want the engine at 130 C. After 3 different sensors, I gave up. Now I don't use it.

been using CS on my Synergy's for over a year with no problems. and all the sensors were mounted with sensor safe rtv. you can tell its sensor safe cause it says so on the label.

From another source........
CSM recommends the use of heat transfer epoxy or RTV so I started to look for an adequate epoxy to cope with the job. I was finally convinced by a fellow modeler to go with the Arctic Silver Alumina Thermal Adhesive which seemed to be the best at the time. This epoxy is extremely heat conductive as it is packed with aluminum particles yet it doesn’t conduct electrical current making it the perfect choice for this application
