Six Pack issues and rebuilding by tommyg29

Thanks Chryco, my existing jets are big at 80 inboard, 86 outboard, but I will start with your suggestion.

The build is mild, close to stock but with headers and 3" exhaust. Also, my choke is disconnected and I will keep it that way.

The fuel tank had about 1/8 (I think) when it happened.

Its hard to tell with the gauge not being the most accurate.

Just waiting on glass sight plugs, fuel lines and bronze filters, then have to pick up a few jets and I should be ready to start reassembling. 

I will use my old fuel lines to get them tuned right, and when I know everything is working well will put the new lines on.

I'm thinking it will be best to get the entire fuel line assembly put together on the bench, carefully using teflon on the threads, and then installing the whole assembly as one unit.

I think I have everything either on my work bench or on its way, except needles. The ones I have seem ok, and the rebuild kit comes with new needle seals, but shouldnt the needles be replaced also? 

Even though Ill probably never need 90 percent of them, I broke down and bought a kit of jets from 65-82. It was the smallest and therefore the cheapest set I could find on ebay. So It looks like I will try 65s and 80s for the outboards, since I already have a pair of 80s from my inboard. 

Might as well check my ignition system while the top of the motor is naked, so I picked up a timing light. 12/36 are the numbers I should expect there. Not going to fool with the advance. Its a great msd billet distributor and Im gonna assume the centrifugal was set up well. 

I have been getting a little run on lately after turning off the key, and from what I understand it may be because the msd system is passing on a residual charge. The fix has something to do with the ballast resistor, which I disconnected years ago.

I HATE run on. Its pretty embarrassing when you pull into a cruise and turn off the key, only to have it choke itself to death over the next few moments. At least its not as bad as  the emission strangled 1974 350 camaro I had in high school (my first car). It was such a dog, it often took almost a minute to choke itself off. My buddies would laugh and laugh, but I was rarely amused.

If I have been getting dieseling, everything Im doing will probably put a stop to it, including new plugs gaped at 48-50ish 

The prior owner used jets of 80s inboard and 86s outboards so you could say it was running rich, and that may have contributed to my problems.

Chryco recommended 80s and I have read that recommendation elsewhere also for my setup.

Finally got to putting the carbs back together after letting things soak in mineral spirits for the better part of a week.

Got the inboard put together with only a few minor issues.

Pulled apart the outboards and found a few things.

First, my front outboard has some minor damage to the outside front of the float bowl that could cause some sticking of the float, but it seems to operate freely. However, the dent made it very difficult to actually remove the float, so something is amiss there.

Also, my outboards have exposed idle needles, and one of the tips was broken off. At first of course I turned them in and found all four outboards out about 5/8 to 3/4 turn, but one of them the point stayed stuck in its hole, and I had to push it out from the throat.

Finally, my rebuild kit only came with one "110" fuel inlet needle valave, so I had to order two more for the outboards. I hope "110" is the correct size. My outboards werent labeled.
