I had real good luck with mine. Plenty of power for Intermediate and pretty much bulletproof once you get it set right.
Mine actually came from Frank, of post #9 above.
As Ed pointed out, the carb needs to be re set to work with the pump. The technique I used was to get the high end right, then close the throttle until it started to get rich. Stop the engine, look into the carb and adjust the low speed needle to where it's just entering the jet at this point. That will get you close.

I ran mine without the pump but with a header tank. Worked fine and didn't have the potential for flooding one got with the pump. It was a little tricky to start by hand the first one of the day but after that it worked well enough. I didn't own a starter that could turn it so never used a starter on mine.
It didn't turn the same props as well as my Webra 160 and 145's did but it worked okay in the light planes I had it in
