Looking for a real good holley carb guru to send out my 2- 500hp carbs for a fresh up.

Still Looking

No guru needed......... I can do them in my sleep.

I use Dean Nickerson in Bristol, PA. but these were more than just rebuild, he did a stage 5 mod. removed and blended the air horn (choke tower) and other internal mods to go improve flow.

Some on this site will voice displeasure, however, I have had only one issue with one of his carbs. The accelerator pump diaphragm failed after 4 years, but that was hardly his fault. Also, jetting was perfect, Same plugs for 4 years looked perfect when I replaced them, tan just like my women.

Since im in pa also that sounds good.

if its just a freshen up, they are really simple to do yourself.

Yea ive done them before on race cars,, just have no heat in my garage where the boat is and would like to just pull them off and send them out as it cant cost that much because they are easy as you said.
Thanks

What are they doing that you think they need rebuilt?

Still work good but one motor was stalling when put into gear and both load up when ideling and they havent been touched in 10 years since new. I have powered up my hp 500s to around 600hp and a crane 741 cam so they may need a little more jet as well.

Sounds like your power valves may be leaking. Have you ran it with the 600 hp yet? If you have I would look at the spark plugs and see what they look like but if the power valves are leaking you would have to shut down after a run and pull a spark plug right away with no idle time.
