Timing issue?
could the intake manifold gasket be causing this maybe once the engine warms up gasket may leak but runs decent when its cold or just started? gasket looks a little ruff maybe in places it is an edelbrock performer rpm foro a thermo quad but im running new square bore gaskets and a summit one inch carb spacer all new on it. no leaks on that part
"could the intake manifold gasket be causing this"
I seriously doubt it.

Are you making assumptions? or have you tested them?
i would hope not considering it was new out of the box 2 days ago lol. from summit like i mentioned. but thank u for the info i may check that out. got the primary float set just fine its just the back is full at idle.
Obviously the rear level is waaaay high.
New don't meanchit any more.
You're gonna need to learn about carbs and such, so you might as well order a Book. If you have an electric choke, then for sure it should have a fast-idle screw on the passenger side, and a mechanical interlock to prevent the secondaries from opening when the choke is on.
My Mopes have never much cared about what brand of plug is in it. The Champions that are in it today were installed in 1999, and have over 100,000 miles on them.
Your vacuum advance us not the problem unless you hooked it up to full-time vacuum and then set your timing to 10* advance. This is full-time wrong for your engine, and fails on two counts.
1) if the engine loses vacuum, for whatever reason, to the point that the vacuum drops out,then the idle speed will drop, maybe enough to stall. and
2) when you nail the gaspedal, vacuum drops very low , and if the engine has a stock timing curve, and was idle-timed with FT advance, it will not have near enough PowerTiming.Yur gonna need another Book.
on a different note;
Are you still running the factory log exhaust manifolds and single exhaust? If yes, make sure something is coming out the tailpipe at speed.
