I just installed the '83 22R I got for my '81 4X4 pick up. I have some minor problems to sort out on it. 1-Since I got the truck to run,it seems to run strong,but idles like it has at least one dead plug. I had replaced the distributor with the one from my '81 engine,which worked fine,so I wouldn't have to change the wiring plug to fit the newer engine. I set the timing at 10 degrees,but I'll have to pull the distributor and turn the shaft a tooth to reach the 12 degrees I want. After I noticed the rough idle,I replaced the cap,rotor and plug wires with those off my old engine,which only had about 100 miles on 'em since new. Didn't help,so I changed to my old plugs,which also had only 100 miles on 'em. That got me a smooth idle for about 6 seconds,then back to the rough idle. If I poke the throttle,it hits strong on all four,but if I float the engine at any RPM,the roughness comes back. This engine shows around 60 psi oil pressure cold,about 30 warm,and no visible smoke or leaks. I intended to run a compression test,but the hose for my compression gauge has gone missing,along with the adapters. 2-Can I run it with just the distributor's advance tube connected and the retard line capped? These two lines and the power brake hose are the only vacuum lines currently being used. every other vacuum port is capped or plugged. There's no smog pump or Cat. Converter on the truck. 3-What kind of a bag of snakes would it be to convert this truck to a normal turn signal flasher? The combination turn/emergency flasher relay hasn't been very reliable and is quite expensive to replace. Speed
