put the baffle back in
jetting a 150 won't make any power you can feel it will only run better .
It's only a 10 hp engine so even if you were to magically gain 25% on power WOOHOO now it is 12 hp see what I mean

Yeah, I agree that the simple jetting trick is noticeable. You can even make more power gains with the airbox. Install a Twin Air Hi Flo air filter. Also, remove the rubber snorkel from the top of the airbox. You should take that main jet back to the dealer and get the 115 main, as there is still more power to be made. The exhaust baffle should be out for the best power. This is what I have found, at least.
My stock 150F with the above changes can do a 4th gear wheelie if I'm at the low end of the rpm and clutch it just right. No way without these changes.

Some people just don't get the respect they deserve...
Way to go on the sticky, Mustang. I've referred it before, and used it some myself when jetting my 230.
