your plugs are not an accurate tell tale of the oil gas mixture. just air fuel. and this really aint even a good way to read a motor.

well it pulls over now with zero compression so could the jugs be f'd it pulls over really really easy with no screeches or nothing so im guessing just the pistons but never know until its apart.

Could just be the rings. But if it was the rings then your jugs will need to be honed or replaced. Get it apart and show us some pics. And what kind of oil were you mixing? Does it say mixable or premix or whatever on the bottle or just injector oil? Just popping the head off you'll beable to know what took a ****.

And what do u think is the best way to read an engine??? Piston wash? EGT gauges? other ideas...?

IMO---Plugs along with Piston Wash is a good way to read how the motor is doing. Those EGT guages can be off quite a bit with not having the sensor at JUST the right place. my 2cents

you never jetted up when you mixed the oil did you. oil in the fuel means less fuel per unit volume of mix meaning you leaned it out and it seized.

Thats what I thought for a breif second but if there was a blow hole then one cylinder would have compression while the other wouldn't. Unless both have blow holes but how likely is that? Man just pop the head off the motor (all you need is ratchet, and later on when you rebuild it a gasket kit) and snap a pic down the jugs or something. Its really simple....and if you don't atleast let me know what it is because I'm curious.

My guess is new rings needed and a cylinder honing or replacement.

Why were you mixing 32:1? I thought sleds were 50:1.

And what was wrong with your injection unit that made you want to premix every time you got gas?

well first off when i said zero compression i meant it was really really easy to pull i was exagerating cuz i was pissed and my guess is my injector is gunked or something because it smoked like a b and oil poured out of the silencer sometimes
