I'm pretty sure I locked my 270cc's up a couple weeks ago. (maybe not all of them, but one is enough to ruin it) The way I guessed this is a sudden decrease in gas mileage, and an even constant rich smell.

This sound about right to you guys? If not, how would you go about figuring out if an injector is locked wide open?

 

If it locked up, it wouldnt open and no fuel would come out. But I guess it would could happen to stay open, but I really dont know. I think I'll ask my buddy Rick Stephens since he is the Mazda guy.

I believe snap-on has a device that checks injectors. It basicly hooks up to the top of the injector and sends a current. If the injector is working properly it makes a buzzing noise.

 

hmmmm....really? I didn't know that..... I wonder if anyone locally would have something like that. Perhaps a dealer?
