Well, it looks like my tuning skills are getting better, but I still have a couple of issues to sort out.
What I have now is the following: start the engine from cold and I have to blip the throttle a bit until the engine will run without stalling. Then, when it is upto temp (approx 65-70C) it will run for about 50 seconds with a decreasing rev count eventually stalling - this was as Josh described in the team trinity website.
If I then press the throttle quick the engine will stall - I have to blip it a few times until the engine cleans itself out, then I can pull away.
At this point the engine will at first four stroke for the first lap, but once upto temp will run cleanly and the temp goes no higher than 100 C.
But when I lift off the engine revs remain high for a couple of seconds - a sign of being to lean, I though?
Also when I come back into the pits after a hard run, the engine temp doesn't drop much below 88C at idle, but if I do the pinch method, then the engine slowly increases in speed and eventually dies after about 5-6 seconds - but this is a sign of being too rich
After the engine has idled for a while, I again need to blip the throttle to clean it out before trying to pull away or else the engine will stall, as it four strokes.
Could it be then, that I have to richen the LSN and lean the HSN? Any help would be appreciated.
thanks guys, Mark.
