haha, j/k but I was wondering how much of a PITA it is to rebuild a holly 650 double pumper (i think its a 4150) ? my dad said dont touch it, it will be a nightmare! but i know it needs to be rebuilt so anything i should know ?

 

No one else tried, so:

Holleys are one of the easiest to rebuild. Get a good quality kit (i.e., not from JC Whitney), have a good clean area to work.

Disassemble per the instructions in the kit. Lay things out in order as you take it apart. Use a real dip-type carb cleaner (not a spray can or generic parts cleaner) to soak the parts. Use compressed air to blow out all of the passages after they've soaked. The kit will likely cover models beyond yours, so make sure you use the right gasket, etc., when putting it back together. You'll have pieces left over, so make sure you've put back in everything you should - not to much and not too little. Adjust per the instructions. Use a new gasket to the manifold (it may or may not come with the kit).

Start it up, adjust the floats and idle, test drive, be happy.

Holleys are easy to rebuild. The first one I ever did took about an hour and a half....now it takes me about 20 minutes.

Get a genuine Holley kit tho, preferable the Trick kit over the standard rebuild kit. It's like $5 more, but worth it.

told ya it would be easy dan. i wouldnt sell you a peice of **** anyways. you know that. oh and that carb doesnt breath fire. lucky you.

 

buy a holley book. the instructions in the rebuild kits cover about every different model ever made. it makes it confusing if you dont fully understand your carb. BTW once youve learned the basics of the holley its a walk in the park to rebuild one.
