2002 honda 750 shadow ace not getting power to the starter. If I jump the starter relay it will start. And my headlight will not turn on. Normally it comes on when the key it turned on. Both problems started at the same time.

check the battery or possibly the bike was in gear with the kickstand down

Either that or the relay that connects the positive lead to the starter is shorted. If you can get into the relay, you may be able to hold the contacts open if the switch is shorted or the contacts may have welded themselves together

It sounds like you may have or will be jetting your carbs. I did this using the directions with the kit and used the Clyman manual for this bike to show me step by step how to remove the carborator. You will only need to attach 2 of the 4 hoses on your carb. syncronizer. If I remember right, you need to remove the bolt-on cooling fins to expose the engine block. The is a black screw or bolt that you take out and screw the threaded metal adapter of the sync tool. Be careful using the sync tool. Be very light on the throttle or the vacuum in the cylinder will **** in the mercury from the sync tool - not good. The problem you are stating on idle & backing off sometimes happens when the carbs are running rich (too much fuel) Hope that gets you in the right direction.

I've posted this in other messages -- I had a similar problem with my 1999 ACE --- the two weakest components in the ACE electrical system are 1) the starter switch 2) the starter relay

Seems the switch goes bad easily..
I would gamble that your starter switch is bad -- I would try some CRC QD Contact Cleaner and then an electrical lube like CRC-2-26 ...
