you may think so i've got like 2 gallons through my magic wheel with no broken parts and not becasue i drive it nicley. it starts on the first pull and is quick. as far as the carb goes the hole not in centered is the linkage. mine runs at close to 300 degrees but runs great with plenty of smoke so it's not a big deal. E_V, when you say it doesn't idle do you meen it stalls as soon as it starts or when you hit the gas. if it just won't idle and is being broken in it's just tight. heat it up with a heat gun or hair drier and that should help to break it in. if it stalls when you give it gas lean the high speed needle a little bit. once you get it broke in and running. get it up to temp and lean out the high speed needle until it runs smooth at full throtle without flaming out. then pinch the feed line and it should idle the same for 3 seconds. if it takes longer then lean the low speed needle until it does. it it stalls right away then richen it a little. it will probably run a little hotter then some engines mine does. it runs hotter then my fantom and my .21 engine in my 1/8 buggy. just make sure there is plenty of smoke and you'll be fine. i hope this helps. i don't pretend to be an expert but that is what i did and i never had a problem with mine. good luck.
