Default MIKUNI HSR 42 starved for fuel

My ride is a 1999 FLSTC... had it from New..
at year 2 I had a stage 3 upgrade because the EVO 80 didn't have the power I needed.
put in high compression pistons hooked header pipes, upgraded cam, and a Mikuni 42HSR carb..
bike ran very well until trying to start this new year.
Bike won't start...
I Drained the float bowl
I put new gas in
I have a Pingel peacock and Lots of fuel to the carb
Change the spark plugs
Put gas in carb and starts immediately but then stalls do to no more fuel

Any ideas what I can do next?

Are you adding the gas to the carb throat or the bowl ?

20+ years that carb has been on your bike, sucking up all the crap gas we have these days. If you are certain you are getting fuel from the line to the carb, buy your self a full rebuild kit and have at it. 2 beer job on a Saturday. Might as well change the intake seals while you are there. Good luck.

Thanks for the feedback... just wanted to check out if I was missing something before I did a rebuild.
thanks again
