Hi guys,
I've been reading up a lot lately on all sorts of different forums about the engine in my dads old hpi baja that I've recently gotten into. A lot of forums say they regularly relpace there piston rings every 8 hours of run time or thereabouts and its kinda gotten me paranoid LOL. When my dad used to drive it he absolutely drove the nuts off of it. I'm talking emptying the tank at full throttle, using old fuel (it did sit for a year or so) and he wouldve done easily more than 8 hours drive time. As far as i know he has done absolutely no engine maintenance on it, and it is the stock cy 26cc engine. I replaced the pull start a couple of months ago and whenever i give it a tug I have to gold the car down in order for it to not come off the ground which I think means it has good compression. It does also start pretty easily even on ancient fuel which I've heard is also not good for it. So what do you experienced guys think? Should I replace the piston ring or is any other engine maintenance necessary? any help would be great.
