No good deed goes unpunished.....After changing out the water pump on the engine, I would run the engine, get great flow in the tell tale but felt no good cooling job would be complete without a look at the thermostats.I got new ones, broke everything apart and had a good 2 weeks of miserable weather.(in other words I forgot how it came aprt) I have reassembled them in the only apparent order that fits but now the engine has no temp!! After running it for 5-10 minutes on the muffs ( the time it used to take to come up to temp) the block and heads are stone cold and the tell tale water is only about 4 degrees warmer coming out than going in.<br />Does anybody have a drawing or can tell me the sequence of the thermostats assembly. The manual is useless and offers no clues. There are the 2 themostats, 2 springs, 2 plastic relief valves that go in the end of the springs and assorted gaskets. In the block there are 4 holes, the outside2 direct water, the inner 2 support the springs ( I think) they all go into a middle cast metal piece then the outer metal cover with the hose outlets on them.<br />I fugure running a 2 cylce to cool is asking for oil build-up. Whatcha think?<br />Seb
