General Comments:
My grandfather bought this truck brand new, and drove it for 10 years, then parked it behind his house and let it sit for about 6 years. When me and my dad pulled it out, and decided to try and get it running again, we ended up spending about $150 to get it running, which included replacing gas, cleaning the carb. and replacing brakes, and it ran like new. Didn't have to replace the clutch until 250,000 miles; that's a stock clutch mind you.
I did end having to pour old oil into the engine just to keep oil in it, because if I didn't the whole engine would run dry in about 2 weeks, but I worked at a shop at the time, so this was no big deal; I would just pour other people's old oil into my truck. It ran great for another 4 years while I put another 400,000 miles on it. Then one month ago I lent it to my sister, and she didn't know you have to check the oil so often, and fried the engine.
We ended up rebuilding the engine, and it ran alright, but never liked doing highway speeds after that. Then about 3 months later the block split, and I tried to find a new engine, but down here in the south people use the r22's for baby boomer racing, so the cheapest I could find was one for almost $2,000 that had 250,000 miles on it. It wasn't worth it, so I scrapped it, but without a doubt, the best little truck I ever owned.
