Default Hello from Virginia beach va

Hello to all
Just finished my first build Thursday I used this engine kit with a speed carb
Using a 32:1 mix
Got a top speed of 23 is that about correct?
Spits and sputters especially when cold the gets a little better but not right to me.

Welcome, and nice build. Personally, I like to keep it on the oily side when breaking in these engines. I suggest 25:1 for the first couple of tanks. I get away happily with about a 35:1 thereafter (I use standard 2-stroke oil and castor (80/20)). There are many different schools of thought WRT breaking-in. I like to keep it at around 20MPH for break-in. You WILL experience some sputtering (4-stroking) until the engine gets up to operating temp.
