hey cheese
after reading a couple of your posts it sounds to me like you've fallen it to a common trap with GO engines where your HSN is to lean and your LSN is to rich with a high Idle to compensate.
this tends to feel like your bottom end is lean bogging but it's actually the HSN causing the bog and the more you lean the top the worse it gets.
A couple of easy checks are to
#1. make sure the engine is up to temp 2-3 minutes of running minimum
#2. give the buggy a good run away and then back to you to make sure that it is well cleared out then bring it to a stop in front of you and listen to the revs.
#3 if the engine sounds like it's over reving (high idle)and then the revs drop back after 5-10 seconds it usually means that your bottom end is to rich.
#4 also try the pinch test - repeat step #2 but instead of listening to the revs pinch the fuel line at about 1/2" (10-15mm) from the fuel intake on the carb. It should only increase in rpm very slightly around 500- 1000 rpm max any more than this and your to rich also.
hope this helps
