Finally trading my rem40e plugs for tempest urem38s fine wires does anybody know what the gap setting should be for the fine wires ?.

Tom,

FYI,

The gap setting is in the Service Manual, sorry don't know the page. Just make sure you check the gap. When I installed a new set about 2 months ago they were off from the factory.

Jeff,
Thanks for the reply, the service manual calls for 0.018 to 0.022 I assume these gap settings are the same for Rem 38/40 + the fine wires a good average would be 0.020 does this sound correct. ?
Thanks Tom c.

Those are the gap settings for massive electrode plugs. I would check with Tempest before I tried to adjust fine wire plugs. I think that they have a different gap. They usually do not require any adjustment after installation.

Tom,
There is a fine wire gap tool that is available from most of the big supply houses that is quick and intuitive to use. It has a fixed gap measurement based on the size of the wire electrode. I don't know the dimension off hand but it's what I have used for years and have great results.

Thanks JEFF jim & ZACH,

I Will look for the gap tool & go for .019 inches the Iridum plugs are in the Engs now and running nice & smooth with the gaps all over the place .017 to .021 as per Tempest "CAUTION DO NOT ATTEMPT TO RE-GAP PLUGS", I'm to anel not to have them all @ the same setting I actually think I might be able to tell the difference,must be that military airline stuff still in my brain.

Thanks TOM c.
