Sorry Frag I didn't mean to cause any offence and I appreciate the help you've given me to date. I'm not making excuses for my lads driving - he's pretty much where I expect him to be aged 8 and I'm happy with our engine builder. I know from experience that dads like to mess about with carbs but I'm more inclined to leave them once I've got them right. I left our race tryton alone after it was set on the dyno and it was stress free for 9 months before I re kitted it and it still works fine. I have tried applying that same approach with the tillotson and sometimes it's spot on and sometimes it's miles off with nothing I can see I'm doing wrong. I've tested pop off on the various spring weights (to check my pop off tester as much as anything) and I found the results to be consistent with what others have posted on here. I run the standard spring in all 3 of our carbs and I'm starting to think it might be a fuel problem and not a carb problem but I don't remember having the same problems with the tryton. I used to buy fuel 5 litres at a time and bin any excess or clean the kart but I've started to buy it 10 litres at a time and top up the clean fuel container. I don't know if this is a problem but it's something I'm going to change. I have changed other things like the plugs though and the oil ratio. We were having a nightmare at clay last event where he reported it kept losing power and I will speak to our engine builder as to what May have caused this. I noticed an airlock in our fuel line but I don't know if this is the problem. I have tried 150ml in 5 litres (3%) and closed the jets to 75 (from 80) on the low as suggested and it works well in reasonably dense air but I found with a reduction in air density I guessed a couple of minutes in on both jets but I have yet to find the sweet spot. On the tryton in less dense air he would make small adjustments to the high jet but I would always put it back in denser air. On the tillotson this is impossible and as for winding the low jet in 5 mins when we took 3 teeth off from 81 to 78 at clay, it wouldn't run properly at all to the point he came in and said the sprocket was useless (his words) so I wound it in 5 mins and it flew. It was fine up until that point on the 81 sprocket.
