Did the guy say he just rebuilt it also? Maybe pull the exhaust pipe off and look up the exhaust port and check to see if the piston is in backwards.

No i rebuilt it and I'm pretty sure I did it right. My dad is a retired mechanic and he was there with me when doing it. Could the reason be that the rings are slightly off than where their supposed to be on the piston. It is kinda hard to keep it lined up when putting the cylinder on.
I'd check it out anyway. Thats just one more thing to eliminate in trying to get it running again.
What exactly do you mean by the rings were slightly off?
Ok. Good thing you took that pic. I threw that out there to see if that would help you. Everything else I can think of has been mentioned.
None that I'd recomend. Order a flywheel puller...I got mine for like $16 shipped to my door off Ebay.
The rings are positioned by pins inserted into the piston, there is no way you can get a jug on if the rings have ridden up over the pin.
Maybe I have spoken too soon, I do know a guy that works for RAG Engineering that managed to fit one FBH style.
Give RAGs a ring!
I didn't see this mentioned at all but I have to ask...is the idle turned up enough to where it will start and idle? Is the air screw adjusted right? If the oil injection was removed was the carb nipple blocked off?
If the oil injection nipple on the carb is not blocked up, you will be running a dangerously lean mix at all throttle openings.
Premature death of a fresh rebuild is imminent.
Every other tube should be open to atmosphere.
..................................................................................................................................
Idle adjusting.
Set float level, make sure that all jets are clean and fuel flows freely from the float bowl drain when the screw is cracked open.
Start with air screw 1.5 turns out.
Set idle screw so that it has some sort of idle. With TORS it is the big screw under seat on top of unit. With no TORS is is the brass screw midway down carb body.
Warm up motor and then set idle screw for a faster idle, 2000rpm+
Adjust air screw either way to get the fastest idle.
Adjust air screw a little at a time leaving 10 secs or until the motor responds.
Re adjust idle screw for desired idle .

Do you know anyone that has one of these machines that you can use thier puller?
