1980 G wont idle.

A dab of rubber grease or oil on the enrichener seals, throttle shaft seals, and fuel tees would be a good thing, but otherwise everything should be dry...

[Douglas Money]

No sealer or lube of any kind. I found that after I assemble everything, I have to trim the inside of the bowl gaskets so the floats don't catch.

I've heard a bit of baby oil on the diaphram slides is all. I didn't use it, seems like it might slide smoother with some oil tho. Again just what I've heard.

I got new idle mixture screws and when comparing them to my old ones they're a bit shorter. so are the springs that came with them. I dropped one in and the threads do screw in. I'm just wondering if i should use the old ones or the new ones? or does it matter?
Here's a picture.

anyone? really wanna get this project moving along.

[DGXSER]

Trey,

You can use the old ones if ou use the new little o-rings and washers (provided they fit properly). Either one should work fine though.

[XSTrey11]

so even though they're shorter i can still use them? that great because if i use them i wont have to feel like i wasted money haha. thanks.

Sure! The carbs aren't super complicated, except for the fact that they HATE being dirty. Take your time and follow the instructions. If you really get into a jam, I'm only 2 hours away. Would make for a nice day trip!

This kind of offer is what makes this community so great! not only giving advice but he gives you an offer for some help. GREAT GUY!

[Lbrown311]

I don't think the new ones will work... the length of the mixture screw is kind of a big deal. If the tip doesn't reach the hole then the mix will have too much air. The tip of the mixture screw needs to fill that hole so you can back it out to the appropriate mixture. Unless I am missing something the new ones are too short and won't reach the opening in the carb body leaving you with no way to adjust your mixture at idle and will produce a lean mixture and an extra high idle.

Those mixture screws control the fuel not the air. And it matters not how long they are as long as they can get down far enough to block the hole, and I think the stock ones don't screw all the way in anyways, these may just screw in further. That said, the later style units are more prone to stripping the slot in the top than breaking off the tip being more blunt than the early model screws, so can be re-used, and it's really just the o-ring that needs to be replace although replacing the screw isn't a bad idea either.

But even if it won't screw all the way down, if it will get down far enough to get the right mixture, it don't matter, but you would have to try.

[XSTrey11]

Okay so we think the shorter ones are safe to use. Now this, and it may be a silly question but in which order do the parts go on the screw? Is it Spring, washer, rubber ring? or spring, rubber ring, washer?

[GLoweVA]

If I remember correctly, the o ring goes in first, then the washer, then the spring. Make sure they are lined up good and not cocked/crooked. Once I had it backwards and the spring pushed into the oring and chewed it up good.

[DGXSER]

Put the spring on the mix screw first, followed by the metal washer, then the rubber o-ring last. The oring is the seal, the washer keeps it flat and the spring adds pressure to keep it seated.

You after i posted i thought "what an idiot" thanks though.

One more thought, has the Petcock been cleaned and rebuilt. Mine had set for some time and at first worked then started leaking. Then the carbs that I had cleaned to a pristine factory appearance adjusted and syncronized started flooding out. Seems trash from the petcocks went right into the carb's. So if the petcocks have not been addressed and you have spent all this time energy and moneyYou still need to clean and/or repair the petcocks. I'd hate to see you go threw this and do a great job and then a little trash destroy your confidence.
