G'day Tyler,
3200-3300 rpm at full throttle is normal for one of these - I have a May 2001 built XTS50 [think it's US origin], on an alloy chassis Masport Maxicatch 550. With the snorkel, too - a very good idea, that.
This one has the Quickcut cutter bar too, and it seems to work pretty well. It does have problems ejecting the clippings in really heavy growth, but doesn't seem to lack grunt, at all. So in these conditions, I just do a first cut at max height setting [or run the line trimmer over it], then a second cut.
With these older-design sidevalve Briggs, they were designed to use SAE30 monograde mineral oil. I have zero oil consumption issues, running Penrite Small Engine SAE30.
From experience, even using a 20W-50 multigrade oil in one of these sidewhackers will result in some oil burn.
