Anyone know of something I might have in my garage or where I can get a gauge to set the gap?
.002” is the gap you need, two cigarette papers folded over will give you that, they are .0005” thick. Although a non smoker I always had a pack in my tools as they were just right to pack a piece on the surface grinder to square an item up.
…and …BONUS! …you can use them to have a celebratory toke in the back seat after. you get the throttle set up.
So I dump out the tobacco, fold it in half lengthwise, and that should be .002?
Yes, that would do it - commercial cigarette papers are probably the thickness Robin states, but keep in mind there are big differences in cigarette paper thicknesses. Comparing Zig-Zag white to Export A - huge difference.
Yes, I rolled my own for many years (ex smoker now)
Anyway, why not pick up a set of feeler gauges and do it right? Feeler gauges are probably the same price as a pack of smokes, right?
I have 3 sets of feeler gauges no .002! But the feeler gauges are also flat, hard to set against a round opening.
I’ve just checked my sets of feeler gauges and mine too do not have a two thou feeler - just 1.5 and 3.0 thou, very strange!
However they will bend easily to fit a round throttle body hole so I’m sure a 2 thou would too
Great, cleaned everything set plte at .002, reassembled and now idles at 2000 rpm, even with the air screw off! I think I will try resetting the butterfly with the engine running to bring it down on the idle.
You’ve got a vacuum leak mate!!
Possibly I will try spraying some starting spray in the area see if rpms change, I did have to open the throttle plate quite a bit so maybe I goofed. Also did not clunt the turns when I remed the air screw so when I put it back in I downseated fully and then opened 1/2 turn, no idea where it should be.
