1.5 Year Project Running, but not Moving Under its own Power

[samhmarco]

Hello 2cylinerhanda Fans,
I am in need of your help. I have been working on my 1971 Honda AN600 for 1.5 years, I have completely rebuilt the engine and it is now running and idling, but completely dies when its under load. I assume its a fuel, spark or timing issue, but wanted you expert opinion.
Please note the following: The wheels spin (or wheel because of differential) when put in gear and vehicle is off the ground. Vehicle starts much better when vacuum advance is heavily advanced. Vehicle starts and ideals very nice. It rev's up fine, but when clutch is let out vehicle starts move but dies immediately.
I have provided videos to assist in analysis:

Thank you so much for your help,

Are the back wheels able to rotate by hand?

[sam marco]

That is a very valid question. I dont know. I thought I was but it would seem that I am not. I replicated the action in anther manual I have by starting to high of gear. The shifter does have a decent amount of play but I thought pushing it straight up was first I could very well be in 3rd I will experiment tomorrow and report.
Thank you so much,

Yes, if the brakes are not applied.

1. Your carb is not fully installed, shove it in farther.
2. That's not idling, sounds like about 3500rpm.
3. When you accelerate your vacuum plate goes wrong direction
4. Better clean & lube your mechanical advance, regap points to .015"
6. I bet your cam timing off by 1 tooth.
5. You need the air cleaner installed for correct running
7. Good thing you are young enough to stop the car without the brake booster installed.

Bill,
I just wanted to share with  you, you were right sir. I was trying to start off in 3rd.... For never driving one of these I didnt quite understand the shifting pattern. Thank you for the advice.
Kind regards,
Sam

Hello Miles,
Thank you for the input. I was actually able to get it running... it helps when you in 1st gear not third...
In regards to #3: should the vacuum plate pull backward or push forward?
Kind regards,
Sam
