Hey guys, anyone familiar with this machine? 1999 Rotax 380 Fan Touring with 360 miles on it my brother left gas in for 2 years. In excellent shape but of course gas went bad, Long story short pulled off carbs and rebuilt them and set volume and mixture screws to previous settings before disassembled. Started right up seemed to have good throttle response but weather was mild. Now in minus degree weather it starts when choked but stalls with small throttle input. If I choke it before it stalls and then then close it and rev it it will go pretty good and when it gets above the idle circuit runs like a banshee. Back off throttle at stop and it stalls unless I choke if for a second. There appears to be a vacuum nipple on each carb covered by rubber boots but 2 different gauges have shown no vacuum when hooked up to them. Maybe clogged? Does anyone know the initial settings for the mixture screws I can start with and then try to dial it in? Any tips on how to adjust these babies? I believe it's getting enough gas and it appears the low speed circuit is the problem. As it's 10 years old there's not much info I can find. I am wondering if there are special gauges I need to get a vacuum reading and so forth. I have some pix of the carbs if that would help.
