Jim Sower Posted July 6, 2002 Share Posted July 6, 2002 Hey all, I am suspecting my CHTs are too optimistic since I am using bayonet probes on the lower regions of an updraft engine. Are there off-the-shelf (generic) plug gasket probes that I can replace my bayonet probes with? Or do I have to go to manufacturer? Just wonderin' where to turn .... Jim S.

Guest Guest Flyboy Posted July 6, 2002 Share Posted July 6, 2002 I would suggest you just going to Wick or ACS for for the spark plug type. All you have to do is make sure they are long enough and are the right type... K or J type. Quote Link to comment Share on other sites More sharing options...
Jim Sower Posted July 6, 2002 Author Share Posted July 6, 2002 <... make sure they're ... right type... K or J... That's what I was wondering. I thought there were more than one type, but I didn't know how many. I guess I'll have to look up the mfgr and find out what type I have. Might as well buy from mfgr if I've done that research with him. Thanks for the heads up ... Jim S. Quote ...Destiny's Plaything... Link to comment Share on other sites More sharing options...
Jack Wilhelmson Posted July 10, 2002 Share Posted July 10, 2002 You can just add 40-50 F to the readings and you will be in the ball park. You can also make your own thermocouples. Buy thermocouple wire from Omega Engineering .50 a ft. for 25 ft. Silver solder the wires to a copper sparkplug gasket. J type is the most common for Cyl. head. K type for exhaust gas.
