When going to spray Clear Gloss lacquer, can I thin it with ordinary lacquer thinner or use the Model Master Lacquer thinner and then clean with ordinary lacquer thinner? Also what would be a good thinning ratio. I usually use a 1:1 for my paints. I usually only paint acrylics though.
Lacquer thinners, to my knowledge, are pretty much the same across the board. Testors might be a little “hotter”, but you shouldn’t have any trouble regardless of the thinner you choose. Since this is a clear lacquer, pigments aren’t going to get in the way, so a 1:1 might be a little too thin. Try a couple different ratios 'til you find what works for you.
Just as a side note, for decaling, I’ve been using Testors clear out of the spray can. I spray some into a plastic cup, and then use a brush to apply to the area where the decal is going to go. No muss, no fuss.

I’ve always used plain 'ol lacquer thinner from the hardware store or Wal-mart. A 1 to 1 ratio would be fine or less thinner if you want a heavier coat. Experiment on scrap to see what you like on the ratio. I use the cheap stuff because you want to run a good bit through your air brush to clean it afterward. Make sure you get it real clean or you’ll never get the lacquer out after it sets up for a while.
I just used the MM Clear gloss laquer using the manufacturers suggested mixing ratio of 3:1 paint to thinner on my A-6E Intruder. The results were very good. The layers built up well using a Paasche-H#3 tip and compressor set at 15 psi. I generally use Future for my clear coats but I cant beat how fast this quality clear laquer dries in preparation of decals as well as a finishing coat. Like others mentioned, I didn’t bother with using the MM laquer thinner- I use the store bought thinners, except when thinning MM enamels for airbrushing. The MM A/B thinner seems to atomize the paint perfectly. Happy modeling!
