tunning help

i have a bv1 and it has the os .15 engine. the running temp is 150F. what i cant seam to do is take of quick. it will always gurgle and then go. do i need to make it run hotter or should i tune the low end needle. i have seen peoples running temps at 230F is this alright. should i lean the high end needle more or lean the low end. im not sure if 150F is a low temp. is it?

any help would be great

Obviously your engine is set too rich, when the engine sets too rich, it'll bogs down when take off, when it's set too lean, it'll bogs down at high speed. Trying to keep your running temp between 200-250F. In your case, you need to lean out the needle setting (always start from high needle and work your way out from there). The character of your engine is depends on how you break it in. My NS12 engine runs great between 225-260. Hope this helps.
