Hey Trpastor, had my buggy out over the weekend to finally give a tune after the run in. Went pretty well overall until a wheel nut came flying off along with a wheel!. Fortunately no damage at all. Just a few questions though. I had it set up nicely by the LHS so its idling well & the run in was no problems after I got a decent plug igniter. Now it seems I have to lean out the HSN needle. I have began to do this in very small amounts. Starting off on the rich run-in settings done by the LHS I first noticed that it acclerates brilliantly but as it gets to top speed it starts to "bunny hop" & splutter as if the trigger was being squeezed on & off then it would stall every so often. So I started to lean out the HSN and noticed that it now runs at a steady idle, doesn't stall but still splutters, just not as much this time. As it got hotter tho, it sorta smoothed out a little, giving a tremendous top speed, but still was effectively spluttering. Is this indicating that it's most likely still too rich and the HSN still needs leaning out? I beleive that leaning out the HSN needle effectively leans out the LSN as well? Does that mean, that as you lean out the HSN, you need to adjust the LSN again? I've got a smart temp and at its hottest it was about 250F, averaging around 230. That would also indicate its still a touch rich wouldn't it? It wouldn't be a servo problem or something? On the whole though its now idling constantly & seems to be getting easier to start everyday so at least thats a positive. Overall its dam fun hey. As these things are not indestructable I don't think I'll abuse it quite like some of the guys on here have. Still an expensive piece of machinery in my eyes. I've already flipped it a few times already without little effort so I can see how easy it would be for things to go awry. Curbs at high speed just doesn't seemed to be a good mix hey. I'm lucky that I have many wide open parks & car parks to run it in without too much for it to run into. Too powerful to run in my street without risking major damage. Could you also outline the difference between the LSN & the Idle screw(the little d*cky one thats a b*tch to get at) & their function please? Still a little unsure of their effect. By the way, that idle screw thats hard to reach, is dam hard to turn on my engine. Is that normal to be so tight? I haven't touched these 2 settings since the LHS tuned it. He said i should only lean out the HSN needle now. Also is there basic maintenance of these cars even a novice can do? Anyway a new wheel nut & I should be up & running again. Back to the park for more tuning. Cheers for now! ps. I feel almost guilty its summer here in Oz & the sun's shining....
