Default Measuring idle gap

There are varying recommendations for idle gap. Just curious how people are measuring it.

Cheers

I measured a paper clip I had on my desk, and it was 0.6mm. I keep that in my tool box, and use it if I need to set idle gap. I don't have to use it very often though....

+1 for paper clips, I keep a pack in the toolbox, .6mm as well, have a couple of .8mm clips but thats a little big.

Measure with ears. All that is needed.

Thanks for the great ideas. I thought about using the verniers and something else later in the evening.

You know what I probably could do it by ear. Why would I if I have a clip that makes it easier to set the gap to what the manufacturer says to.

Why do we measure shock oil? 35wt 40wt
And diff oil.
Why do we balance tires?
Why do we use springs with colors specifying the spring rate?

Because it is all best practice for performance.
It relieves me when I don't have to guess because without that clip that's exactly what it would be is a guess.

Plus I like my clip. Hahah.

Back in the day ...I've seen Ron Paris did it by ear and sight when tuning young Swauger's car . Works for me. But I see what you mean.

Tell me how to measure silicone oil? To my knowledge we only trust what the bottle says. The same with springs or do we all have a spring rate meter?

The problem is that the idle gap is not a steady thing working on its own or determing other settings. It is the last adjustment to the carb in finding the right tune and it is really a setting which must be done on a feeling or sound. The LSN and HSN together the the kind of fuel and weather is finally determing the idle gap.

I don't measure it. Your right. I trust losi on that one. But it is measured. :-)

Your right on the gap being only a part of the a steady idle. I think that part confuses a lot of newbies
I traded some tires for an engine I knew had less than two gallons on it. The guy just got frustrated with it. I checked the carb and the gap wasn't off at all but the tuning was all screwed up. A new plug about 15 mins of tuning and it was a different machine.
I still ended up putting my werks carb on it though.
