TrollHole Cruisers Carb Install on a 60

60-Series Wagons - forum.ih8mud.com
Got my new 2F desmog carb directly from Trollhole. He's importing and selling F and 2F carbs for desmogged motors. You can read more about them here.

I decided to do this before our club's annual Over the Mountain Tour run, which was being held at Coal Creek OHV this year, 4 hours from home. This should be a good test for the carb to see the improvements.

I had recently desmogged the truck, and it was doing well, compared to the fully smogged state. But I was still having a flat spot issue and the truck still felt slow, with the stock smog carb.

Below is the engine with the stock carb and my hack desmog.

Took the old carb off and set it beside the new one to see the differences (the new one is on the left and shiny )

Notice the identical linkages but no vacuum pots.

Driver's side view, no choke breaker, no A/C idle up (it is easily transferred to the new carb), and much simpler.

Front of engine view - same viewing window, shaft for A/C idle up, and one fuel line in.

Passenger side of engine view - only 1 vacuum connection, advance for the distributor.

Moving the A/C idle up was very easy: remove the screw on the shaft, the 2 screws holding the bracket to the top of the carb, and slide the vacuum pot off. Repeat in reverse to install on new carb. I did use the original carb screws in the new carb to make sure that I didn't have them bottom out or barely make contact.

With the old carb removed, the install was VERY easy. Slide the carb into place, replace the linkage bracket, tighten the 4 nuts, hook up the fuel line, and you're golden. The one large vacuum line on the top of the stock carb is not used with the new carb. I think it is for the charcoal canister, and if I remember correctly, can be plugged.

Initial start was a little slow, I imagine it was trying to pump fuel up to the carb and get the air out. Once the truck started, it ran smoother than it ever has. Quiet too. Took a quick drive to the gas station and it was a different truck! It pulled all the way through the rev range to red-line. It is actually fun to drive now, but kinda makes me scared to push the ole 2F that hard w/ 205k on it.

On the trip to Knoxville, it performed flawlessly. I was able to accelerate uphill, and could have pulled the local mountain (Hwy 25 near the Cliffs) in 4th probably, if not for slow traffic in my way. On the way to Knoxville, I averaged 15mpg. Not bad considering that included a long uphill pull, and several floorboard sessions enjoying the newfound power.

A couple of things I've noticed is that most times the carb cranks almost like an EFI rig, half a turn of the motor, and it's idling. Also, when wheeling, the truck would basically die, and if I got the clutch in, the carb would bring the motor back to idle. AWESOME.

I am sure that I have some more stuff, but that's my quick write up. All in all, I'm very happy with the product, and imagine anyone else would be too. Definitely worth the money, IMHO.

Thanks Trollhole!
