Im 36 and I remember when gas lasted forever ,my farther had stored our 1968 skidoo back in 1988 full of gas and we pulled it out in 1999 and it ran on same gas no joke we still talk about it .

[@ToomasTelling]

@@Zachsmoparandmashedpotatos because it was pure gasoline no junk mixed into it. i run non ethanol gas in my 2008 Cadillac STS and i can drive way further although the engine is desing to handle ethanol. i also own a Volvo XC70 4x4 lifted wagon and it even says in the owenrs manual for best efficiency and power run non ethnol 98 octane gasoline. so the regular 91 or 95 ocatane gas is junk these days.

@@ToomasTelling we used to have a small air port in my area where you used to be able to go and get great gas but once it became commercialized that ended

The accelator pump lever has 3 slots..try the top slot..see if that helps..also try the a stronger spring step spring for the primaries ..edelbrock sells a spring kit..different colors..the plain color heavy spring opens the spring the fastest..the avs secondary flap shouldn't be causing that stumble..

Nick you are Mr. Mopar; your knowledge and attention to detail is the best ever. My first car 51 years ago was a 69 GTX. I loved that car; after putting on over 100,000 miles it was stolen and never found. Keep up those great videos. Stay well. Joe from New Jersey

As a Chrysler mechanic for 45 years I can tell you that stumble in cold weather can be caused by no heat stove on the exhaust manifold and hot air tube going to the air cleaner. The sensor for the vacuum going to the air doors also has to be working.

[@Bruce-fr3ot]

I will second that , I bet if you power brake it slightly you will see those hot air vacuum door motors will open a the engine will fall flat on its face. Back in MN we experenced that all winter long. We used to install a delay valve in the vacuum hose and make sure those doors don't open on slight acc, also with a temp gauge inside air cleaner door doesn't open till 110-120 degree's.

[@enduser6982]

A guy I grew up with had a GTX 440 4 speed. It was built for street racing. Steep gears and you could hear and feel it fire across town. It had the first and only three barrel I've seen installed on a car. It had a pink lace job laid down. There was another GTX 440 4 speed outside of town a few years later. I swore it left the ground like a plane taking off.

I had a good stumble in my AFB. It hadn't been worked on for a long time. I sent it out and had it restored, sure made a big differance. A few months later I sent the distributer our and it was rebuilt, that toke care of the rest. I run 10.75 comp, but I run GOOD gas, 50/50 VP-110/ethenal free 92 oct. I run 10degrees to start and 38 total comes in at 2800-3000 rpm.

That lumpy idle brings back many memories. My brother-in-law had a '67 (or '68...I need to check on that) Barracuda 340S...what a beast! In the still shot at 28:25 I can see a Jensen Interceptor in the background. A beautiful British-American hybrid. I guess if it has Mopar power under the hood, Nick is the man to bring it to...👍🙂

[@IRONHEAD12701]

I remember working on Carter carburetors. They can be a real pain in the tukas. Rochesters and Holleys seemed to be easier in my recollection. Been 20years since my last wrenching days.

I grew up sitting in the back seat of our 70 Satellite and eventually got my drivers license in that car. I always wished dad had got the GTX rather than the 225. My uncle got the GTX and dad hated him for it.

Nick listening to that 440 on the dyno screaming like demon is gear head food for a Mopar Monday. Doesn't get any better than that. Taking the GTX out for a test run was fun.

Eugene. I should have your AVS Carb coming soon to the shop this week. We will try it on the Dyno with your engine set up. Who knows, it might work well. If not, the Dyno room has other carbs for trial and testing. Covid 19 has hit one of Rodgers employee. We have a CURFEW here in Quebec since last week. We have to stay safe no matter what. Will be calling you soon Eugene, for engine built. Stay safe.

[@eugenecastles7475]

@@nickpanaritis4122 You are right the AVS properly tuned might perform well on my engine. If it doesn't you might try rebuilding the 3310-1 carb that was on the motor when it arrived at your shop. They don't make them like that anymore, especially with the downleg boosters, just a thought that I had. I'm sorry to hear that one of Roger's employee's came down with Covid-19, I hope that he gets better soon. we are still have problems with people here in the states not taking this pandemic seriously. We need to follow what you are doing in Quebec, with the lockdown, and curfew. Everyone needs to stay safe, I have been living like a recluse since this started, only going out when absolutely necessary. Looking forward to hearing from you. Best wishes to you and your family.

Beautiful gtx!💪💪💪👍

[@wbrowning52ify]

The problem with old fuel is that the butane in it evaporates. That causes the octane rating to be lower and gives the lower end temperature ignition to be at a higher value. The vapor pressure is also lower which means that the volumetric rate of going to a vapor state from liquid state is lower. This occurs when going from a pressurized state to a vacuum state below the carburator in the intake manifold. Basically, old fuel with low butane levels changes the air fuel ratio and has a lower octane rating which causes pre detonation in the cylinders.

[@telicogarage]

Good morning everyone. Sweet gtx

[@NicksGarage]

GM used the Quadrajet, and it used to have the same problem. I used to tighten up the Velocity plate spring, over the Secondary's, adjustment and it would cure it.

I run a mix of VP-110 and 92 ethenal free, motor is 10.75, it loves good gas. I sent the AFB and distubutor out to be rebuilt and restored, that made a big differance. I run 10degrees startup and 38 total, coming in at 2800-3000rpm.

[@jimjungle1397]

The Mopar AFB and AVS carburetors have three step metering rods and matching jets for them. They can be fine tuned by using the Edelbrock AFB two step metering rods and jets, primary and secondary jets, by using the non-raised Edelbrock metering rod covers for the two step rods. Then jetting and timing can be adjusted for power. The two step metering rod jets should not be used with three step metering rods. Three step rods are meant for specific jets made for them and the two step rods are meant for specific jets made for them.
