Excellent video. Less and less people understand how to tune up particularly carbureted applications. Also even less people understand how critical the vacuum advance is if you're going to actually drive your car. I have a friend that was advised not to hook up his vacuum advance and he has like a thousand miles on his engine and the spark plugs are already fouled because of no vacuum advance.
One thing I do see that most people overlook is that most of our fuels are 10% ethanol these days and that changes the stochiometric ratio from 14.7 to around 14.3. they're also seems to be a misconception that you cannot cruise around with your engine at 14 to 15 to 1. I've heard a lot of people that think you want the engine at in the 12 to 13s all the time and that is just way too rich for cruise, lots of carbon
For my Holley carbs, I have the choke plate removed, but kept the fast idle cam attached. It keeps the idle high when cold but doesn’t enrich the mixture too much, pulls from the transfer slot and not the boosters. With a Quadrajet, I use the choke, they can run very lean at idle and needs the enrichment.
Seems like the cars after 1974 were made to fail in 10 years like the story of the Preachers one horse shay.. except the opposite. I have taken so many of the valve cover filters and thrown them against the wall to replace them with proper PCV to stop oil leaks on cars. Second is when people have a stuck choke and wonder why it smokes. 3rd is they have the factory plug wires on a 40 year old car. Turn out the shop lights and tell them look at the light show while I let it idle. Well if it will.
The warmer plugs have a longer insulator so the water jacket doesn’t suck as much heat out of the electrode. You want the plugs to get hot enough to self-clean like a self cleaning oven. Too hot and the ceramic will start eroding and develops a matte texture. I always run my daily driver plugs on the warm side, just hot enough so the electrode starts showing a matte surface gives great idle quality and fuel economy, also makes for easy starts in a cold Canadian winter.
Hi Gold's garage i have a question about kickdown cable hookup or adjustment i replaced my 2004r transmission with an th350 and i can't get that adjustment correctly do you have a video on that
