Regarding the exhaust, I have not found one that caused any issues, always the carby. One other thing to check is the main jet is clear. Before I went too far I would try a bit of starter fluid in the plug hole, sometimes it wakes them up. And don't be fooled by the plug being wet, I don't know why that happens sometimes and it won't start, but if I modify the carb they usually fire straight up and then you have full throttle control. Some days I might modify 3 carbs with probably a 90% success rate. The odd carb I just can't get to work for some reason, they just end up in the spares box
