Bike motor has almost zero power, but starts.

Then I would be curious to know what the compression of the engine is.

Also want to add that I think the compression was playing up around the time that I blew the engine.

I was gonna say that the video was pretty informative

Good! I'm glad it was helpful.

I don't have the HP carb from bike berry I got it from Amazon.

They're probably the same or very similar.

Hopefully it works!

Good luck!

I was gonna say that the video was pretty informative and I ordered a set of jets from 52 -70 so I'll give the #65 a shot. I don't have the HP carb from bike berry I got it from Amazon. Hopefully it works!

They're all the same, not going to work very well.

I'm pretty good at making thing go but couldn't make the HP carb work.
Here is a video of me and my people. About 50 seconds in.

I don't quite know how I can easily test compression. By best idea for you is that I can not spin the wheel without sitting on it, I can't move the bike from a stand still without clutch, but above 8kmh with pedalling I can turn it over a few times. Any tips on how to tune the idle screw on the carb? I forgot how and I know it's kind of a thing u need to feel for but still would like to know a good idea.

2 easy ways to test the compression.
1. Use a drill with a 14mm socket and spin the motor over clockwise using the magneto nut.
2. Spin the rear wheel.

Drill is easier, but alas, we may not all have one.

Has anyone been able to make a hp carb work properly?
All I have heard about them is bad.

I have 2, and the one I got it to run real good up to just before 3/4 throttle, then it would 4 stroke and bog out. But what good is a performance part if you can't do a zillion?

hp's are dellorto clones, right? I bet a real dellorto would work
