FHMan1905 Posted December 13, 2010 Report Share Posted December 13, 2010 Just wanted to say hi. I have a 1981 720 with a z22 powerplant. My dad bought this truck brand new and I am not in the process of getting it going as a little beat around truck. I have already ordered a few parts and now just dealing with the normal issues of a truck that has sat for about 10 years!!! Going to drop the gas tank and have it boiled and steamed here locally. Truck still runs like a champ with fresh gas. Ordered a new weber carb conversion, so i am pretty anxious to get that in! Just wanted to say hi....I will have tons of questions along the way!!!!

FHMan1905 Posted December 18, 2010 Author Report Share Posted December 18, 2010 Got back in town today to find my new weber sitting in the office!!!! Looks like i have some plans saturday....any tips or tricks from anyone who has done this? Quote Link to comment
Sealik Posted December 18, 2010 Report Share Posted December 18, 2010 (edited) Got back in town today to find my new weber sitting in the office!!!! Looks like i have some plans saturday....any tips or tricks from anyone who has done this? Easy install...obviously you have no smog testing? Your Weber should have come with a 2 piece IM adapter for your Z22. Also need a fuel pressure regulator...set at 2.5-3lb. Edit This is a actual Weber?.....or a knock off?

FHMan1905 Posted December 18, 2010 Author Report Share Posted December 18, 2010 Installed.....just have some minor mods to have it completely hooked up!!! Quote Link to comment
Sealik Posted December 18, 2010 Report Share Posted December 18, 2010 Installed.....just have some minor mods to have it completely hooked up!!! Hmmm....mine sits 180 degrees the other way....with the elec choke facing the pass side Quote Link to comment
FHMan1905 Posted December 18, 2010 Author Report Share Posted December 18, 2010 Hmmm....mine sits 180 degrees the other way....with the elec choke facing the pass side Yeah but if i did it that way the throttle cable doesn't reach, so i figured a few extra of 10ga wire compared to throttle cable would be easier!!! The only question i still have is my throttle cable has the lead "ball" on the end to keep it from pulling out, but the trunnion on the weber only has a small hole for the cable to go through....seems like the cable just slides through the hole and then tighten down the nut and washers to sandwich the cable?...will the cable not pull out? Also...i notice you have the same plug I had going to the factory choke....but my plug broke...which blue wire do I need to tap into to run the wire onto the choke? Quote Link to comment

The Weber should come with an extra 'trunnion' that will enable to run the stock cable....no cutting Cable is long enough.....mine worked fine....even on the Z22 I initially put it on Just find a (blue) 12V wire...powered up with key on Quote Link to comment

FHMan1905 Posted December 18, 2010 Author Report Share Posted December 18, 2010 factory trunnion works.....had to use a couple of washers to space it out some...but works...just need to drill out my support bracket!!!! Quote Link to comment
FHMan1905 Posted December 18, 2010 Author Report Share Posted December 18, 2010 There is a threaded fitting coming out of the intake in front of the carb with three vacuum lines to it....what is that?....A wrenched slipped today and broke off one of the vacuum nozzles and now sprays small about of fuel out....either need to buy a new one so i can cap all the vacuum lines, or take the whole fitting out and plug the hole in the intake with a bolt!

TVV?.....Thermal vacuum valve...(I think)......A plastic fitting? No gas should be coming out of it....just coolant if it's broke. Wax is heated by warm IM coolant and just 'opens' it up, thus air can now pass through (top) it. It won't leak if there are no hoses attached to it. Plug it, if it's NFG.....other wise it can be left as is, per pic Here's one....colored blue Pull and cap all the lines.....including the EGR Quote Link to comment
FHMan1905 Posted December 18, 2010 Author Report Share Posted December 18, 2010 that is basically what it looks like...i just assumed gas since it was on the intake....I guess i will just take it out and find a bolt to match the threads and plug it. I have removed all my vac lines just haven't capped them yet. Since i am not inspected or have to worry about smog i have been told the only one i need is the distributor vac line Quote Link to comment

I have removed all my vac lines just haven't capped them yet. Since i am not inspected or have to worry about smog i have been told the only one i need is the distributor vac line There is 1(?) vacuum switch which controls your EM plugs, on your passenger fender....which you will most likely be disconnecting also. Just make sure that all of your 8 plugs are firing when all is said and done. The 83+ has a white wire coming from the dizzy and when this is unplugged.....all 8 plugs fire....all the time.

FHMan1905 Posted December 19, 2010 Author Report Share Posted December 19, 2010 So I need to leave that one on too for the EM plugs also. Mine is an 81 Quote Link to comment
Sealik Posted December 19, 2010 Report Share Posted December 19, 2010 So I need to leave that one on too for the EM plugs also. Mine is an 81 I think if it's removed....it will still fire all 8 plugs. It just senses a vacuum change under a load and shuts down the EM plugs Quote Link to comment
FHMan1905 Posted December 19, 2010 Author Report Share Posted December 19, 2010 What did you use to plug the part of the exhaust manifold where the factory aircleaner hose tied in? Quote Link to comment

FHMan1905 Posted December 19, 2010 Author Report Share Posted December 19, 2010 That looks nothing like mine!!! Mine is about a 1" to 1 1/2" inlet into the manifold Quote Link to comment
