nitro stan

whats up all, new here but not nitro.
i looked through the GO engine thread and didnt see what i need to know.
i got a GO .28 3 port sport, its not very tight (new). should it be? sence its not a race spec engine. this is what i was told by a couple people

iv got 7 tanks on it so far and it runs like its going to be a beast when im done

its got 3 shims on the head botton, should i remove one? im running byrons gen 2 20% race fuel

thanks stan

If it came with the 3 shims installed I would finish break in at least before I would emove 1 of them. Maybe 3/4-1 gallon.

I agree. Keep the shim in for about 1 gallon then if you want a little more power remve the thinner .1 shim. Or you can just swtch to 30% nitro and keep the shim installed.
