I have decided to rebuild the carter that came on the boat because I found a rebuild kit on eBay for $30.  I was not surprised at what I found when I opened it up tonight.  But I do believe this would cause the issues I am seeing with the motor bogging down.

I would definitely clean the snot out of all of that. Soak it in some solvent or something. I am glad you are making progress towards the water though :)

Yuck, that's a decades old disaster in there ;)

Lol..I can't believe it was running, have you ever removed the air cleaner...it should run like a champ now.

This is the carb that was on the boat when I got 2 years ago. it set for five years before that. When I got it I put one of my holley carbs on it. when I took the motor out my dad decided he wanted the carb that was on it. so I had to put this one back on but forgot I had not cleaned it until he reminded me. lol. so here we go the kit should be here tomorrow or friday and the time to get smelly and redo it.

here is what I have after a 45 minutes soak and then going over it with can carb cleaner.  it is now flowing through all the jets.  it is not as tarnished as the pictures make it look.   tomorrow I will clean some more then put it back together so maybe I can take her out on saturday.

Looks like you got some help ;)

Always!  makayla is truly a dad's girl and as long as I am in the garage so is she.  it doesn't matter what I am doing unless I am using the compresser because it is loud.  All I have to do is grab it and she is gone LOL.

the carb is back together, oldtimer is on the suburban and ready for another water test tomorrow.

oldtimer idled better and was more responsive.  she still seemed to load up at speed and pops but at least it recovers better.  I am going to change plugs and try again this weekend.  I think I am going to watch the choke to see if it is either closing or open at speed.  I may just have to make it stay open and deal with a cold natured boat.

Bring in your high speed needle it should only be one and a quarter turns out.

I will try that.  I put them at 2 turns like is recommended.  but I have not had a chance to try to adjust it yet

I dont miss owning anything with a carb besides my weed whacker

Right...

This is the one I get to mess with on a seasonal basis

That's nice what year model camaro is that?

70 z28 good work on figuring out what car that was.

I am a huge fan of the the older camaro.  my dirt track cars were a 1974 and a 1978 camaro.  plus that the piece of the head light gave it away.  only the camaros and firebirds (for a while until the tried to make them look different) had a headlight profile like that.  my dream camaro is 1970-1973 split bumper z28 with a big block.   

This is the full pic.. I love this body style

Bring it in a quarter turn then test, leave the low one alone. If that doesn't work you may need to go with a smaller jet.

I just had a thought.  I believe we are talking about different carbs.  I have a carter on the boat not a holley.  I have a holley but I put the carter on because it was the orginal carb for the boat.  so I believe with a carter the only external adjustment you can do is the idle mixture screws. 

Awesome looking car! Is that chameleon blue green?

I thought thet carter had a low speed adjustment as well it's always hard if you don't have tha carb in front of you. Another thing too look at but is highly unlikely is the amount of fuel in the float. The bogging at high speed sound like a jet. I ran into the same problem building my motor. I also ran into that by using the wrong intake. I polished my intake ports so the air wouldn't roll in the intake causing a hesitation at high speeds.

Carbs are fun... :D

Using my iPad with a split keyboard so sorry for the grammar

Very cool, I had a 98 Trans Am that color. Absolutely loved it.

My high school hot rod was a 74 Camero.   

To this day I still have an occasional dream about driving that car.   

Me too I love that body style what most people don't know Chevy put a Tom of research into that car. It was a beast for its time..
