1984 228 305 carb problem

[FORREST3]

Just a few I've done.VERY RARE ones also.. ram air 400's or 455 HO's mostly convertibles..I did ALL the work ( INCLUDING ENGINE teardown and assembly.). no subbing out except engine machine work ( boring, valve jobs)..all by my self. with sometimes a helping hand from nephew..LOL..enjoy.. sold all over the world to rich collectors! Curious what you have accomplished dubs?? I welcome you to come see me and my shop and property (115 acres) in Oconee Ga.. I look forward to it! OH.. 2 of them sold on BAT (bring a trailer auctions) One sold for 150,000..a few months ago..I sold it 16 years ago for 87,000.00... look up 1970 gto VOE convertible.... you'll see my name there in the comments..and so on! YEA.. I know nothing about NA engines..LOL..marine carbs?.. Yea..I needed help with that!?

If you're confirming your earlier post of saying a vacuum leak does not increase rpm then yes, you really do not know how a naturally aspirated engine works.

Read my post.. a MAJOR vacuum disonnect from intake source should not cause a LARGE jump in rpm's ( a big jump in rpm's caused from excess air/atmosphere means engine/carb. is running way too rich)..I have 2 completed 70 GTO"s here.. to confirm..both are tuned perfectly..a large intake vac. source disconnect does not cause a jump in rpm's just a pretty rough idle ( wayyy too lean).Turn your mixture screws all the way in on a perfectly adjusted carb. Runs crappy, right?..why? too lean?..Maybe marine carbs behave differently..I don't know..probably not.. the logic is there though..so I guess I don't know..

Wow, you're still stuck on the auto stuff, it's great you've managed to acclaim some self pride though cars

You can keep posting useless info about your success however it cannot change science and the fact a vacuum leak increases rpm. Lovely pre DeLorean cars BTW. But if you have never owned/worked on a Vauxhall you know absolutely nothing about GM, associated companies, nor any components related to their products

Yes I'm proud of what I've done.. but boy do you know how to ruin a day..and hopes of help from others...Were done dubs..could have discussed our differences..but You chose to insult me..some advise..curtail your opinions to others I hope..leaves a bad taste for these forums....please don't chime in on my posts again..you know too much..it intimidates me.."captain" lol...wow

Can't know enough about engines and boats. Glad to hear your advice seek on this forum is finished. I do provide factual information based on what I know, have experienced, and confirmed in real life about boats, boating and most important science and life on planet earth

After your adventure outside everything humankind has learned from this ball of confusion perhaps you will actually enjoy boating, your choice in automobiles would consider otherwise but there is always hope. Good luck, citizen

dubs, are you proving your expertise by picking fights over small things? Putting people down is not fun for anyone but you.

 

[dubs283]

picking fights over small things?

You agree that a vacuum leak decreases rpm?

Find someone else to fight over your mole hills.

My "hills" are facts. If you cannot observe reality your existence is moot and has no reason for reply

You did not respond to post #27

Thats his MO… must be making up for other inadequacies

Just so those interested for future reference.. seems I found the problem!.. One of the primary jets not tightened all the way down..Jeez! Allowing extra fuel in bowl at times. Go figure...re tightened both and now have no leaking from the primaries..also vacuum is back to normal as it should be.. not running rich and idle mixture screws and "ALL vacuum" work properly as they should!.. Thanx most all for the help!
