Winter Qtr starts again

Not a lot of hours in the shop so far, and wont be for the rest of this quarter due to extra general ed classes I'll be taking, but I do have a little bit that I've picked up so far.  BTC's Yale forklift was burning coolant and poofing out loads of smoke, so I finally got the head off today.  I want to do some more research in regards to what kind of unique wear that propane has over gas.  I did figure out that it has a very similar engine to a 1988 mazda b2200 2.2L FE (still haven't found the engine tag).  Also put a little time into seeing how a propane system works, and it is pretty much the same as gas.  A little conversion kit is all it took, and it burns the gas like any other fuel.  Boom! and the crank goes round.  Pretty basic, but I wanted to make sure before I tore into it.  I'll get some pics of the gasket and head damage after I do that propane damage research.  

Total hours must be around: 18
