I just bought a 1987 22r and have been trying to iron out its many problems... The engine sounds like the choke stays on even once it warms up. I just fixed a couple other problems (alternator and leaky water pump) and was just getting to the choke issues when I noticed the top radiator hose was hissing after the engine was shut off. So I replaced it. I filled the coolant back up, sprayed some carb cleaner in the carb, started the engine, and after a few minutes it began spewing white smoke. Lots of it. So much that I tried to ignore it and back out of the driveway but could not see. Initially I thought head gasket, but I drove the truck for only about a mile yesterday and it was fine....not sure why it would have failed just now. Also, no signs of badness in the oil. Lastly, when I turned the engine off and looked at the carb, the passenger side plate was wide open, which if I am reading correctly means the choke was disengaged? So while the engine sounds like the choke won't disengage, it appears that it has... Any ideas? is there hope for this thing yet?
