Awesome idea - I'll check it first thing tomorrow. Today I found that the fast, rough idle was caused when the velocitator pedal was depressed too far, it wouldn't come back up fully, but after i stuck my toes under it and pulled it back up, idle would come back down and settle. Over-revved while changing gears too, and could have been part of a compound problem; that is me revving the engine more to get the clutch fan spinning faster, but then going back to idle with engine revving too fast and transmission in neutral. So currently, the pedal doesn't spring back to original position when released, i'll try greasing the pivot point, but can this be also caused by a bad spring? Also - also also also I noticed, there is a summer/winter switch on the left hand side of the carb with two intakes, one that recirculates preheated air or one that draws cooler air from below, will check it and flip if neccessary tomorrow, as it's summer here now. I noticed all this stuff tonight, in the dim light so it's no time to start meddling... Cheers for all the responses guys, I'll post some pics tomorrow because this this is immaculate for 1989, has custom bullbar and large canopy, fitted with a mattress and camping gear! Bush Brumby!

Thanks alot for the feedback guys. I've been checking and topping up coolant daily since the issues started, the temp gauge never entered the red, the temperature does stabilise and it runs ok, but a new radiator/flush sounds like a plan, along with the colder thermoswitch. (rainy days are ok, but the hot summer days really make it that much worse) There's no A/C on this model. Twin electric fans sound great, but I'd have to cut the shaft off the crank fan in order to fit another one in there! The crank fan is close to useless. I'll post some photos of the engine bay for those interested, I've never seen this type of setup either. The rough, fast idle is the main concern now.. hopefully after a major service it'll come good. Cheers!

Hi all, Recently I purchased myself a 1989 BRAT, which I love dearly.. it had full service history, which was frequent and lavish and seemed to run fine. I gave it a good inspection, changed the oil and coolant and drove straightaway to Melbourne (2000kms from where I was). Highway driving was fine, then i noticed the heat rising when i climbed a steep grade... wasn't much of a concern as it just rose above half then settled back down, but what I didn't know (should have checked) was the thermostat was faulty... so the thermo fan hasn't been running for god knows how long... it has a mechanical fan also which works fine. So the other day I was driving in city traffic, and heat started climbing, and rose to about 3/4, and was close to 4/5 before I pulled over cursing and realised what was going on... I hardwired the thermo fan onto 12v and now the engine runs cool again (about 1/3) even in traffic... but just as a test, i disconnected the thermo fan and now she gets quite hot just from idling and driving around the block, and never really used to. It has also developed an abnormally fast idle sometimes, which causes the engine to shudder after being turned off, needless to say, I hate this sound. There's no white smoke, and the oil seems fine (no milkshake) but the oil fill point is a tube that leads to the engine, not directly on it like other engines, so i can't say for sure what the oil looks like. It's driveable and goes fine other than the idle sometimes, but it's concerning. I'm going to take it to a mechanic asap, but is it possible i've even cracked the head gasket or manifold gaskets just from a mild overheat? Is there anything I should check or change myself that may be causing the idle problem? In eager anticipation... thanks guys.
