Update on carb problems

[supercopjason]

I adjusted the secondary float yesterday and had it running better. Went and adjusted it more today and i hav a "tinging" noise when i put it under load. Most noticed at WOT. I never though about it because it kinda sounded like an exhaust leak but now sounds louder. The jeep seems to run quite a bit better.

If it's pinging you've got it leaned out. If you feel the carb is all good at this point you could search up some threads on here about working the advance on the distributor to eliminate the ping. There's a couple of routes to accomplishing that, it sounds like you are getting dialed in though.

ok checked timing and it was at close to 20* so i moved it back down to about 12 andi still get what sounds like a tapping noise when i give it throttle..

ok time for the dumb question of the day. When i give it gas while looking at the timing it moved alot. Is it supposed to move? i then hooked it back up to carb vaccume and it still moved just took more gas and longer.

As far as the carb i am at a point i feel like i have no idea what im doing anymore. just doing the same thing everytime.

Is the timing supposed to move?

Is the timing supposed to move?

Yes. Did you disconnect the vacuum tube from the dist and plug it while you adjusted the timing.

Even with the vacuum line removed from the dist. You should see the timing move from the mechanical advance inside the dist.

[supercopjason]

yes removed vac and plugged. then hooked it back up and it moved less hooked up.

I did go adjust the float levels again. Am i in jeopardy of blowing my engine with this "ticking" noise? It starts off lite but under more throttle it gets pretty loud. it didnt make this noise before but also shot fuel out of the secondary fuel bowl sight hole when i pulled the screw.

Do i need to just take this thing to a mechanic? Again if anyone wants to make some cash or maybe come out and shoot and have a good time.

Im freaking out here!!!

GGGGGGGRrrrrrrrrrrrrrrrrrrrr.......

I adjusted the secondary float then went for a drive around the block and now i pulled the sight screw and it poured out.

[supercopjason]

ok i cant really tell any difference when i try and adjust the secondary float. The tinging has been bad since i adjusted the secondary float. I am taking the carb to a specialist today.

Could i have damaged anything with it pinging?

Did you ever see the "specialist"?

Have you changed your power valve yet? If not you are getting no enrichment under acceleration, therefore running lean which can cause pinging.

If you remove your spark plugs, check for grey/silver spots on them, that would be small pieces of your pistons Don't worry, most likely you didn't cause a lot of damage if you didn't drive it for a long time with the pinging.

Just changing to an 8.5 power valve should fix your pinging issues and give you more power. From there you will probably want to change to 66 jets and a .35 or .38 accelerator pump squirter. But first start with the power valve, and always only make 1 change at a time.

Went and saw the guy everyone around here recomended. He works on all the funny cars and alco racers so he is highly touted. I didnt change the power valve because i was more worried about the pinging blowing my engine up. I did adjust the secondary float to low and ended up dropping the needle and seat so low it wasnt adjusting anymore. Also when he popped the carb open in front of me it was in horrible shape. There was a lot of rust settlement (i guess from the PO but it looks like i need a new tank) and all the o-rings had rotted.

[newellm]

Heh, having rust in the bowl could certainly cause all sorts of problems. Is he going to rebuild it and give it back to you and help you tune it?

Sounds like he should be able to get it running good for you if he does help you tune it. Give us an update when you get it going again.
