"I dunno about that one Justalurker, when I look at both the X-300 and X-500 specs, the X-500 is 3" longer overall (75" vs 72"), and the wheel-base is 51.2" vs 49.4" for the X-300" Look at the parts lists... the frame on the X500 and the X300 both sub to part # AM137099. you the hood is also the same. "With a 48" deck, the X-300 weighs 616 lbs, vs the X-500 at 760 lbs. No doubt though, the X-500's larger tires/wheels, larger engine and trans-axle, account for some of the 144 lb difference" Wheels, tires, K72 with larger oil capacity and 1" axles, larger engine, and the two piece body on the X500 instead of the smaller one piece body on the X300. "The X-500 is also 3" wider (approx), but that's probably due to the wider rear wheels/tires" X500 has hubs on the rear axles with bolt-on rims AND the offset of the 12" rims.

Yes, show me any new single cyl. 14 hp gas LT/GT today, that will at idle, drag a 3000+ lb car, with no front wheels on it, easily as one of these old tractors. No, in no way to they compare to the comfort, or creature comforts built into todays machines, but i for one, if i want comfort, ill drive a car, it all about toughness in machinery to me. And hope no one gets their dander up cause i say this, i know newer stuff can be bought that is as tough , and usually do more diverse work, but when you throw in the nostalgia of old iron, and how simple, and how tough they were, its so much fun to use them

Yes my 2001 Montero Locked Up out of the blue while idling. No oil light whatsoever. I just notice it suddenly lost power as I was about to park it. Then engine died in a way like it locked. Tried cheater bar to turn engine no luck. Recently though I charged the battery full and it budge a bit so I turned again with a cheater turning opposite direction and it did. It turn about half way. There is hope the engine can be fix while on the vehicle. Maybe bad camshaft or broken valve spring which bent the vavle. Worn rod earing would have thrown oil light or any bearing that is worn. I may add too that I recently rebuilt the head myself so there is a posibilty I may have Installed the valve train rod backwards which would cause the oil hole not to line up causing oil starvation on the cam shaft, I did notice loud valve noise when starting the engine that diminish once it start but gets loud when raising rpm. I also want to mention it also had broke valve spring on piston 1 but I fixed it amd ran like a champ before it locked up in me.

Having same engine idle problems. 92 chevy Scottsdale 5.7L, 104,800 miles.Starts and runs great but, when it warms up setting in drive with foot on brake, the engine surges. Idles down then back up (like a stuttering). Sometimes, when driving between 35 and 40mph it will do a little hesitation, but when I give it gas it smooths right out. I have replaced TPS, engine temp sensor, plugs, wires, 02 sensor. new fuel filter, disconnected the EGR vac (No difference), tested MAP it is good. So,a few months ago I had a new Distributor put in, it seems this is when my problem started. No saying this is the cause, but yesterday when when starting it for the first time and after a min or so the distributor started make that sound again (bearing) after engine warmed up it stopped making the noise. So I m thinking I have a crappy distributor. And yes I put in a Carquest dizzy. Had no choice the 3 auto stores around here all have crappy after market parts so I thought Carquest was the better choice. So it looks like I will be replacing this dizzy with a AC Delco if I can find one. Maybe you guys can check you distributor for your problem. Hope my impute helps someone. any feed back advise is welcomed. Email me jdcron@wmis.net as I may not see your response.
