I have the screws as well, and the TORs I'm running are the straight-through types.
If you decide you wanna try the 155s, we should get togehter and swap -- I have a pair of 155s and 160s that're lying dormant.
I also need to check to see if the port-side vacuum seal on the top side of the carb is seated properly -- when we pulled it apart last time we had a bear of a time getting it back in... so we sort've stuffed it in and hoped it would self seat. I'm wondering if that's the problem, I'll find out tomorrow. Still, you'd think the bike would be consistently wonky -- right now, teh low end is much better than it was, but the top end is utter crap.
