Think that would be about the same with the 35mm? I started with 175 main and have went up 2 sizes everytime. I've gotten all the way up to 190 and it flattens out on top. No backfiring, just doesn't pull any harder at full throttle. I threw the 175 back in it yesterday and I think it was actually better, so looks like I've been going the wrong way.
I'm not sure at all which way to go with the pilot. It has a 48 in it now. It won't start cold without choke and it hesitates a little right off idle. I'm thinking it's too rich and I need to go down a couple sizes, but you would think it would crank without choke if it's rich.
