I need to know what size the bearing is for the .26. I can't find the info on it.

I do have to say I like the Matrix, but I have not had much luck with the engine. I only have about 12 tanks through it and I can not get it to run worth crap. (won't idle right, stalls at random, High temp, ect) I even had a guy who has been racing for years try and help and it was baffling him. I even went as far as taking it apart and sealing it but it just will not run right. Now this last time out to try and get it to run, it seems the front Bearing is leaking.

does anyone have a suggestion

thanks
