The AMC 290 V8 was not based on the Ford 289. It was designed by AMC. AMC sourced transmissions from other companies, but they designed and made their own engines except for the GM 2.8 V6 and 151 I4's they used in early Cherokees and the Buick V6's used in some Jeep CJ's. They were going to use a GM rotary engine in the AMC Pacer but GM pulled funding on development of it so AMC had to shoehorn in their own 258 I6 and 304 V8 instead.

The large displacement AMC engine in the 70's was 401 CID. AMC/Rambler made some great cars. I had a 1972 AMC Javelin. Great car!
As for the poll, I'll take an old fashioned station wagon. Forerunner of today's SUV's.

Those are typically one vacuum port, one fuel in port and two fuel out ports. I just capped off one of the fuel out ports on the one ebay sent me by mistake and it works fine.

Vacuum is separate from this. It's source comes from the intake manifold of the other side of the carb. The pistons downstroke pulls air from the intake manifold, carb, snorkel, and cleaner/filter assembly. Having a nipple on the other side of the carb still produces vacuum, but (depending upon several factors) it is not as strong as at the intake manifold itself. Spray a cracked snorkel with ether or starting fluid and the engine revs because vacuum is drawing in the fumes from the outside of the snorkel. Your suggestion is viable for returning oil to the crankcase once the filter reaches saturation, but leaves the problem of the vacuum. This is where the PCV valve comes into play. The PCV valve only allows air out, so on the pistons up stroke it actually pulls a vacuum on the crankcase. I believe I'm going to combine our ideas. Between the valve cover vent and tee I will add a filter, then the pcv valve to where the line used to meet the snorkel. This should keep oil in the engine and vacuum pulled on both cracnkcase and gearbox. Anyone feel free to dispute my logic with this as I'm still learning. The hose going to your snorkel is pushing air out from the crankcase. Plugging the nipple on the snorkel, or putting on a snorkel without a nipple, will not effect the vacuum supply on the other side of the carb. Vacuum, as used on a scooter, is a product of the combustion chamber, not the crankcase. There is really no benefit to put a PCV valve on your scooter. The filter will keep water and dirt from entering the crankcase. |

You might want to check the variator to make sure the rollers didn't get turned out of place. That happens sometimes when a belt breaks suddenly.
Harbor Freight has a good plug in impact tool. They sometimes put coupons out for it a $39.99. I've got one and it works great on the clutch and the variator.
This will give you some insight into the rollers:

The part you are referring to is not called the intake. The intake is on the other side of the carb. Since your new snorkel doesn't have a nipple on it just take a fuel filter and attach it to the end of the hose and tie it off to the frame somewhere above the engine. That will allow the crankcase to breath and give any oil blown out a chance to run back down into the engine. The purpose of the original setup is to direct any oil fumes blown out of the engine a chance to recycled and burned in the engine.

When MacArthur made his "I shall return" statement, Roosevelt was still alive and in charge during WWII. What MacArthur got in trouble with Truman over was the way he wanted to conduct the Korean War. MacArthur wanted to pursue the North Korean soldiers across the Yalu River into China. Truman feared if that was done it might draw the Chinese into the war. When it appeared as if MacArthur might ignore him, Truman had MacArthur report back to the States where he was relived of command.

I think all three deserve the title. All of them would call it as it was and made the tough decisions when it counted. Of course I would never want to cast any dispersions on their modern counterparts!  |

I believe this is a two stroke. If so, no valves. Pull the carb and clean it good.

The "square petcock" you refer to is the fuel pump. It runs off of the vacuum pulses the engine creates when turning over. Did this issue just start? If so it sounds like you need a new pump. You can try priming the carb bowl with fuel to get it to start and see if it starts the pump working.

Too much! You might be able to get by with subbing in a standard GY6 coil.

Check the cable routing. Make sure it is taking the most direct route to the carb. Of the two adjustment points, the one where the cable attaches to the carb is used to make big adjustments. The point at the throttle is used to make minute adjustments. At the carb attach end, loosen the top nut and slide the cable barrel down thru the bracket until there is no tension on the inner cable, then tighten the lower nut. Watch as you turn the handle bars from side to side. There should be no tension occurring on the inner cable at the carb attach point.
Once adjusted properly you should have about 1/8 to 1/4 of an inch of free play when starting to turn the throttle before the cable starts to move.
Take time out to watch the Seahawks game!
