RE: high speed

If the engine sounds like it's drowning out it probably is. Is it spitting raw fuel out the pipe? What is the main (high speed) needle valve set at? The factory recommended settings are really rich, and you need to lean them out as the engine gets broken-in...

RE: high speed

it is tuned to run normal at regular speeds or as far as i can tell i dont understand though how it only does this when it shifts to 2 or a little above 2nd

thanks
