Ok so I ran it last night and was back and fourth with the top and bottom. So going off the needle settings above I first tried rob's suggistion. The pinch test gave me a high idle up and took for ever to die. But I left it knowing the bottom was rich and top was lean. Ran a few laps to tune by ear. Down the straight it was on fire. I could hear it at top rpm about mid way down the straight. I knew it was way too lean then and bottom was ok but still had a load up issue. Brought it in and it was 296 ouch. I know that took some long term life out but im glad the rod didn't snap. Came in opened the high speed needle about 1/2 turn to get me in the 200-220 temp area and did a few slow laps to cool it. That half turn was actually really good and I kept it there for the night. The bottom is where I struggled. 1 to 2 turns lean I would get a slight bog as if it wanted to cut off. 1-2 ours rich I had now bottom power. I would have to take wide turns for it to clear just to make baby doubles. So when I put it back to the setting in the pic above the motor ran ok for a practice motor but I would've race it as is. The mid to top was awesome and bottom I could make the smaller doubles but barely. You could hear it clearing out from 5-15 percent throttle and after take off like a bat at out off hell with plenty of smoke. I'm gonna try to get my GO pipe back or maybe post for another. I know pipes play a big role in power band but didn't think it would make or break a motor. But I'll find one and try it again.
Thanks for the feed back and I'll drop in with updates.
This is a long post but wanted to also know how many gallons are these motors getting if ran right and are the newer carbs worth getting? This is my first 2 needle carb. My old Go had another type of carb but I can't recall which. It 1 1/2 years ago. In fact the time I meet rob for him to check the insides. The intech br5 days lol.
