Grrr.....Not again!!!!

[Thirdgen89GTA]

I really don't know where this one came from. It wasn't running hot at all, plenty of smoke then suddenly it started acting really lean, high idle, overheating, stuff like that. So I shut it down, backed the high and low needles out a half turn and tried again, but no matter how rich I went it didn't run right.

I finally got it to idle and run right but power was down from what it used to have.

The funny thing is I've been testing and tuning all week long with it and its run fine every day. I'd usually go do 3 or 4 tanks of playing around the grassy area by my apartment complex. But after an hour out there it just started acting funny.

I didn't realise the block was cracked till I went to remove the engine from the car to clean the chassis and one of the mounts just fell off. It still has compression, but I hope it didn't screw the sleeve and piston up, I don't want to replace it so soon, its only had a little over a gallon on it. I will likely send it in through the hobby shop. The head has never taken a hard hit like that.

I was going to buy a 528 for the buggy, and probably will too.
