Lol I don’t even know what cam is in it! I probably used this oil before but good to know that it’s got some thumbs up here lol

I have some 20W-50 VR1 “High Zinc” in my shop and am planning an oil change. Is this too heavy? Information: Flat tappet 340 High compression 12:1? Older engine oil pressure was on the lower side if I recall correctly maybe 30 psi but don’t recall what oil was used. Lives in Phoenix and it’s...

I saw that as well. Apparently there are several carbs of this type. The 777-7 is not a four corner set up however the 777-C is….

Thanks your advice got me looking at the choke. It was the choke and it was full on causing this. I feel pretty stupid. Oh well, live and learn. Thank you for the input!

Great this will be very helpful. Been watching UTG vids as well!! Any thoughts on the curb idle return issue I am having?

It’s not any of the cables or linkages as I have disconnected them all. Still will not hit the throttle stop screw which is turned in all the way.

The other issue I am having is the that the throttle is not making it to the throttle stop screw. No where near it actually.

Welp I can’t get a paper clip more than .25” in the hole so it looks like it’s not a four corner after all. Can you guys help me understand the other issue I am having?

Lol quite possibly as I stated I am not familiar with these. Yet….

Here are some pics Looks like this model is a 4 corner adjustment and indeed mine fell out while handling it prior to installing it. From Holley’s web site.

Yup the AF set screw now I know what you’re talking about! Thanks! It was in there must never been set right bc it must have fallen out….

Do you have any more info on the bracket?

Is there a decent parts diagram that can identify that rear set screw? I don’t know where or what screw that is. Also the idle set screw doesn’t engage and there must be a reason. It is like it’s 3/8 too short but I know that it’s not. Does the carb need something to bring the idel set point...

Hey guys I am not very familiar with Holley’s and carbs for that matter. I am in the process of getting my 340 running again but have some questions on my carb. Is the lever with the black spring that I am pointing to connected to the throttle linkage the secondary throttle body control?

Chaching

Thanks!

Just tried to PM 63GT his fricken mailbox is full.

Click link on post #4 and click on his name and send him a PM….

Looks like all you have to do is message 63gt directly….

If you don’t have sight plugs then is float height just a mechanical measurement while disassembled? Like my motorcycles?

Does anyone use those clear see-through float bowl plugs? Seems like that’s a great idea rather than spilling gas anytime you wanna check float height. But I’m not sure if they work very well. Oh and are these used just as a diagnostic tool or run permanently?

Hhaa yup

Test fitted carb.

I can’t see any numbers on it but I believe it’s the stock pulley.

Another taste….. 77% said paint. So I did and I am super happy. Now if I can bend and shape my kickdown bracket to fit all would be right with the world!

I went to the hardware store to see if I could match the color of my manifold. I asked if they had “infected dog but” but they just ran out and said just wait.

No the holes were good. I used JB Weld and tapped them in. I test fitted each plug as there was some variability, so some plugs fit better than others.

So I am still waiting on my thermostat water housing. I assume that not having a thermostat relief for the thermostat to sit in the manifold is normal? The relief must be in the mating housing?

For future reference who/where is Leanna?

I had this in my shop. Mixed a little slow reducer.
