In the engine forum, there was a thread about the evo 100 and a change in the throttle spring that caused some problems. He said that he stretched the spring, then found a replacement that had more tension and that fixed his problem.

In another one, the issue of hotter glow plugs came up.

And, yet in another one, someone replaced a carb (as was suggested to me) and that fixed it.. he put an OS carb in its place.

This is the first time (only because I've not read it anywhere else, not that it's not the first time it's been mentioned, just the first time I have heard this fix) that someone mentioned about the o'ring at the carb base. Perhaps that is the fix, I don't know. I removed the mixture restrictors from the needle valve, and made low-speed adjustment galore with no light at the end of the tunnel.

So, I won't belabor this issue, I just lost my faith in the Evo engines and that's that. Hey, if you guys are having great luck with them, then more power to you. I'll stick with the OS's. At least I have confidence in them where I lost it with the Evo's and I feel that I did give them a fair chance.
