Post subject:  Getting this thing tuned up correctly?
Okay, I took it out for a test run and it's running warm for one.
It sounds like it's flooding out when I give it fuel.
If I hold the throttle steady, it hesitates like it's starving for fuel?
The timing I set to around 15 after?

What is the proper proceedure to getting this thing closer to running right?
I am thinking that if I stomp on it - instead of dying it should scare the hell out of me?
Also need to get the kick down linkage figured out. I thought I had it, but didn't notice any "kickdown" when I stomped on it - like I said, it sounds like it's just flooding out.

Gonna try again tomorrow to get it right.
I took the pinched tranny line off and was able to put a section of fuel line on there for now. I will be getting a better setup on there as soon as I can though. Don't want to keep the fuel line there very long - don't trust that!

Anyway, it sure was nice to have a vehicle again!
Just can't wait until it's a kickbutt vehicle!
Later,
Dan

It could be that you need to do this:

If the timing is really set to 15° after TDC, that's going to be a large part of your poor/hot running. Try 5° before TDC for a start.

Thanks Dan, I'll give that a try in a little while.

It's cold and rainy AGAIN and I have to put my heater back out in the van to work on it AGAIN - the old sore bones ache too much right now. One of the biggest problems I have when trying to do anything anymore.

Isn't there a place in here somewhere that tells the correct proceedure for getting this thing closer?

What I mean is - set timing, then idle speed, then adjust carb?
Or set idle, then adjust card, then set timing
Or??
Oh, and where is the kickdown adjustment proceedure?
I tried to follow what the books have and am not sure I have it right yet.

Know what I mean?
Brain not exactly working on all 6 cylinders anymore either ya know!
Thanks again Dan,
Dan

Hey Whale, don't know what mods have been done, i.e. runnin throttle cable instead of rod, etc, etc. But outta my A100 FSM says this.
With engine at OP temp and idle set at 500rpm, disconnect tranny control rod at the carb bellcrank. [At the carb base]
Hold the tranny throttle control rod full forward so lever at tranny is against the stop. Adjust rod lenght so the ball socket alings with the bell crank, then snap onto the ball end.
Now, Disconnect throttle control rod at the carb base bellcrank, adjust the rod to provide a pedal angle of 115* with ball socket aligned with bellcrank ball end, then snap it back together.
Road test for kickdown operation. If tranny doesn't kickdown, lenghten tranny control rod 1 turn and repeat test.
SIDENOTE from ME!!!- On adjusting the height of the pedal is a crapshoot and a pain. When I did my Sup-six conversion, I swaped over to a cable[go-cart] for the throttle and it was a test and tweek til I was happy with pedal height.
As for timing, etc. set timing first to where you want it. Mine's happy around 10*btdc, adjust carb speed and idle mix. When happy there recheck timing, and test drive.
When your all done you can come and drop my / for me! :D
Just kidding

Well, I just tried to get it to BTDC and when I try - it won't even start - it just tries to backfire.
The closest I have it right now is at 5 after and it is still acting like it is flooding out.

69 - I thought that's what I did! As to the kickdown adjustment, but I guess I will have to try it again. One problem I am guessing I have is the length adjustment on the rod going up to the carb from the kickdown lever. I had to find one and I just bent it until it was sitting in the holes as close as I could get them, then I went through the adjusting proceedure you described. Oh well, with all these f'n meds - looks like I'm gonna have to try it again and again until I get it right.

I am running linkage - not cable on all this too.
And as far as the "dropping" goes - I would Love to help - cause that means that I got this thing running right finally!

Well, it doesn't seem to matter where I set the timing - it still acts like it's getting way too much fuel.
I have 55 and 73 jets in the carb right now - that's what it came with.
I adjusted the needles to 1.5 turns out from bottom.
Should I try leaning them out?
Or?

I also hear what may be a vacuum leak. It isn't there all the time, but it sounds like a high pitched whine at idle - and disappears when I give it any fuel. Gotta try the starter fluid around the carb routine and see if there is a leak.

I am starting to wonder about the cam - I just dot-to-dotted it when I installed it since I have no idea how to degree it in. One of those things that may take me weeks to understand and figure out how to do!

Oh well, I guess I will just keep plugging away at it.
It's gotta get better - right?

What kind of carburetor are you running...? Guessing some kind of Holley 2bbl?

Well, they need to be set correctly. 1½ turns out is in the (very) general ballpark, but it's not a spec, it's just where you set them so that the engine will run, no matter how poorly, so you can warm it up to do the final adjustment. You set the idle speed to spec, then close the mixture needles clockwise ¼-turn at a time or so (both needles the same amount) until the engine just begins to drop RPM because it's too lean, then you open the needles back counterclockwise ¼-turn at a time or so (both needles the same amount), keeping track of the number of ¼-turns, until the engine just barely begins to drop RPM because it's too rich. Then, you close the needles clockwise half the number of quarter-turns you counted between lean fall-off and rich fall-off, and that's your final adjustment.

Carburetor cleaner is easier and far safer to work with for this test.

Thanks Dan - I'll give that method a try next!

I have the timing showing at almost 30 AFTER TDC!

This is - SO FAR - the best that it runs. BY FAR!

I'll let you know what happens with the needles - and, it's a Holley 500.

AND I definetely need another kickdown linkage, linkage- the way mine is set up right now, it doesn't kick DOWN - it pulls up! Which in my opinion - DOES NOT WORK!!! :D

Not too mention the shifting - I have to start the damn thing in gear right now because the shift cable just bends at the top and does not push back into the lower gears!

Hey, at least I know that my luck is holding true to form!!
If it weren't for bad luck I wouldn't have any luck!

Thanks guys,
Dan

Sure you're using the #1 plug??????????

Otherwise I'd think the pulley damper has slipped and you there's no clue of where TDC actually is..........

Um, that's cause it's Sunday... :D But yeah, 30 after should barely run (if at all)... I think there's the very real possibility that you have some balancer slippage going on there.

It's either that, or the dampner is from a different vehicle.
I tried and tried to get it to run nice at the 5BTDC mark and it would only act like it was starving. It would backfire and it was heating up more than I figure it should.

Once I put it to where it is now, it acts like it should - lots of pep if ya know what I mean.

Now I still need a shifting cable and a kickdown linkage that I can use.
The kickdown I have does not work.
If it isn't one thing it's two or three others.

Typical of my luck!
Oh yeah - prime example of this - I ran it down to the local store out here - 2 miles - put 15 bucks worth of gas in - 5 gals - and came back here - got here and started smelling gas - searched around and guess what I found? The damn fuel hose that runs from the filler tube down to the tank was leaking! It all of a sudden decided that it was too rotten to hold the fuel! Another thing I have to remember to fix now! See what I mean about my luck?!?

Dan, are you disconnecting and plugging the vacuum advance hose when you set the timing? And is the vacuum advance hose connected to a ported (not manifold) vacuum source?

I am plugging it - and I have it connected to one of the connections on the bottom of the carb. There are 3 there - small, medium, and large.
Small - vacuum advance on dist.
Medium - plugged
Large - pvc

I adjusted it again to 5BTDC and now I'm gonna try and get the jets adjusted.

Will let you know in a little bit what it's doing.
It sounds to me like it's barely running and I cannot adjust the idle any higher on it right now.
