<font face="Comic Sans MS">Sir, sorry about not scanning that item I promised a little while back from Holley that they included with my rebuilt Varajet II carb, my scanner's been down. I will take it over to a friend's house and try to get it scanned this week for sure. I'm assuming you can see the little square adjustment knob on the front of the carb and it doesn't have one of those plastic limiting things on it. Have you tried running some carb cleaner through it? As to the butterflys sticking, have you tried spraying the linkage and the butterflies themselves with cleaner and perhaps even locate a stiffer throttle return spring.
I got my rebuilt Varajet II (done by Holley, came in a Holley box with plenty of doccumentation including how to track other problems down) from Pep Boys for somewhere around $400. If you drive it on any sort of steep hills, I think the stock varajet would be the best choice, any incline I've been able to put the truck to hasn't even phased it, just keeps running great, no threat of stalling or any such thing. I have no experience what-so-ever with Weber carbs. From information I've gleaned from the Toyota board, they (the ones with the Webers) have cold drivability problems, they can't drive them or the engines run horribly until the engine warms up due to the Weber. My Varajet II takes off great, I just have to wait the second or so for the oil pressure to come up and I can drive away and have the engine run great. Here's one link about the Toy people talking about the Weber
I'm sure there was a longer thread talking about it, but I can't find it at the moment... [img]/wwwthreads_images/icons/crazy.gif[/img]
And it ran great right out of the box, I didn't have to touch the settings on it at all, tossed the new gasket on (came in the box with the carb) and bolted it down. Haven't had to touch it since I installed it. [img]/wwwthreads_images/icons/cool.gif[/img]
I'm not sure how the Edelbrock route would work but I would assume that a naturally aspirated 2.8 L doesn't need quite that many CFM. I think that Edelbrock option would be more suited to the 3.4L (bigger relative of the 2.8L, same bolt patter on bellhousing and such). </font>
