Title: Plug Gap
Post by: pep on March 25, 2019, 11:04:13 AM

Change the plugs frequently  .......... cause there is a very nice performance bump when done.

Wondering how many set or even check a plug gap. Thought I'd bring a tool to the table that will not only speed the process. Exact and even gaps are totally repeatable every time.
 A manufacture preset gap will have a range + or - small detail that dose have an impact.
FWIW

You set the dial to a specific gap width and slide the plug electrode and ground into the gauge and press the handle - bingo!! gap set to whatever you dialed with the gauge. Old School, but it works. Not recommended on iridium or platinum tipped plugs though -- it's very likely you can chip the thin electrode with these tools

 Here you go,  set the gap size, open the gap some, then insert plug, close and set gap.

@ Ray LOL yeah that one you have there certainly is old school. I find the gap sizing disk interesting, but limited looking it over.

Have actually sold a few of the gapping pliers.

As to gapping plugs for work, small engines get gapped to 30 and if I am in the shop I will gap them.  On the road, they get eyeballed most times but can't say that I have ever had a problem with a plug gap done by eye but then again, we ain't talking high performance or high rpm

The gapping pliers are nice. Makes the job quick and easy. I've seen some of the supposedly pre gapped plugs be way off.

I always check gap before I install new plugs.

Never seen the pliers before.

I had a set just like Rays, back in the late '70s, they were in my toolbox----in the trunk of my '68 Roadrunner.

Some SOB decided he wanted it more than me (the Plymouth), never to be seen again----at least by me.   :'(

I always check the gap after pulling a plug or putting new ones in as it is habit. I don't have a fancy tool to do it though.

How do they adjust for different lengths of plugs?

I bought one in the early 80's off the Snap on truck. It came with a disk that went up to .035.  Bought a second disk for wide gap HEI plugs.  Probably not useful for a single, but saved a lot of time on a set of 6 or 8.

The collar that the plug rest in, flips it is pinned off center, and changes the length.

Disk is .085 now
