Elect6845 does a great 346xp as well. He actually sent me his newly ported 346 for me to try with not agreement to purchase. I ran over 10 tanks of 40:1 through it without issue and continue to use it hard with great results, it pumps out 172lbs of compression. I'm pretty sure he knew I would have to buy it. You just don't send a saw of that caliber down the road. I need to save a little coin and get my 346 xp and 576 in the mail as well.
