Sorry Bozo Hadn't rely looked at this thread in a while ....yeah, thanks for your answer to my direct question.
To fit the intake I had to widen the mounting holes.slowbalt,
Did you have to modify the HT intake manifold for use on the HF engine?
Also, what kind of throttle controls are you using on the handlebars?
What is your elevation there? Where do you get the jets. I haven't run a China girl carb in a good while now. This is like starting over. I have one of the older NT carbs and figured I'd leave it be with the unused engine it came with and pick up a speed II version of the NTUpdate. I found out that I did have jets to fit the NT style carb. It is actually the Speed carb. It's just like the NT but with a fuel cutout built in. I actually needed to go bigger on the jet, not smaller like I had originally thought. I started with a 70 jet and ended up running an 85 jet. It was fuel starved with the 70. It idled nice but would die with very little throttle.

Thanks!I got the jets from Ebay. The speed carb takes 5mm jets. The Rt I have takes 6 mm jets. I'm at sea level. I filed the mounting holes open then used 1/2 " bolts to hold it on.on.
