Draw 2 "freezing/locking up" and "Windsaver" noise

I'm new to the chromatic after playing blues on diatonic harps for 25 years. I was gifted an inexpensive Swan 1040 and started messing around with it. It did play pretty smoothly and although the slide was a little clunky it sounded good except that it wasn't very loud and apparently not very air tight. You could actually bend some of the draw notes like a diatonic as well. Looking in it you can tell there are no "windsavers".

So I looked to upgrade and decided on a Suzuki SCX-48. Still not too expensive but around $200. It has a much better tone and the slide is great. One problem I'm having with it is on the draw 2. If I try repeated draw 2 notes it will just "lock up" the reed and not sound. My cheap Swan does not do this. So I contacted Suzuki about it and they said it was all in my technique that is common to blues diatonic players using too much air and that I would need to learn to play with the instrument. It does make sense and I have tried to play around it backing off some and it seems to mostly have worked but not totally to my liking. So I was wondering if there was someting more I could try to modify the harp to make it a bit more responsive on the draw 2 and occasionally on the draw 1.

The only other thing I have started to notice with it is a bit of a buzz from the "windsavers" especially on the draw 1. In fact if you play in a quiet spot you can really notice the "windsavers" popping up and down on both blows and draws on holes 1 to 4. Maybe this is just the way chromatic harmonicas work or maybe the Suzuki I have is still on the cheap end of things but it's a bit distracting

Looking for a bit of advice and direction on learning better technique if that's the issue or on modifying or setting up the Suzuki SCX-48 to sound better or trying another Chromatic.

Thanks!   Craig
