put in a hotter plug a 77t or 87t odonnell plug is perfect. factory seting on the low set needle is to rich to run so lean a bit there until you get a nice idle.
always heat your engine and put it on the ground and start running in with short blips of the throttle heating and cooling cycles is the best way imo just follow the run in guide in the engine section that engine will take nearly 2 gals to run in so take it easy and dont lean to soon.
cheers
ps just run a 7mm carb insert
