The 2.25 petrol isn't going to well at the moment, she's blowing big clouds of blue on start up and the oil is getting low (wonder where it's going) and there's oil being pushed out the breather. It isn't as smooth as it used to be and has less power than before (if that's possible) and it gets hot quick. The clutch is slipping and its just getting old. Time to organize the motor to replace it, I've found a wrecker that'll sell me a 186 for $100, another wrecker has the conversion plate and I'll need to see if he's got the engine mounts and source a spigot bush and do a light rebuild before I drop it in (rings, valve stem seals, few gaskets and couple other bits) should have the old IIA moving a good bit quicker when finished.
