Do you have the stock screws in it? Reason I ask is I once used Keyster kits. Thought it wouldn't hurt to put in new kits. The replacement screws had holes in the bottoms. The stock did not. Couldn't keep plugs from seroiusly fouling around town. Put the old stock screws back in and no more problems. I need to mention I'm riding a 75 750F. Our carbs are different and I don't have a clue about yours.

I haven't changed the fuel screws, if thats what you're referring to, but maybe PO did.  I don't see any holes in the screws.  I think your carbs have air screws, mine directly control the amount of fuel in the idle mixture, so i don't think there should be any holes in them.

That Harbor Freight tester is the cheapest I've seen by far. If it turns out you'll need a 14 to 12 adapter for it, you can try these folks:

The cheapest specialty M/C compression tester I'm aware of is around 30 bucks.

yeah, i called the place and they said they have them in stock here in Austin for 4.99!!!  I can't quite tell if the thing has a 12mm thread before the fittings though.  I called napa, autozone, advanced autoparts, a bearing place, a hydraulic place, and nobody had a 14mm to 12mm adapter.  THANK YOU FOR THAT LINK, I PROBABLY WILL HAVE TO ORDER THAT ADAPTER.

If the Snap-On truck visits your area you can buy one from them. At Snap-On prices, of course.
