Hey, What do you think is going on inside my 13B? When i have started it the last 2 times(putting it away for the winter) It has only started on one rotor then after 30secs or so it would run on both? What do you think is going on in there ?

I dont really care because me and my buddy are building a motor over the winter. I am going all ceramic because i will be getting a really good deal. I dont know when i am going to be starting but i will end up ripping this motor apart to rebuild it anyways. I never had the chance to really drive the car much because i bought it just before snow fall. Its put away for now. When i bought it i knew the motor was tired.

I'm thinking possible low compression on one of the rotors.

capn

does it stay consistant like every time it starts on one then goes to two?

how do you know if only one rotor is working??

fstrnyou

it makes half as much noise.

I would do a compression check on both rotors and come back with those numbers.

Because i have working on alot of rx7 and i know when there only on one rotor. I have also had a blowin motor before and i know how the one rotor sounds and feels.

I dont know if will do it everytime but the last 2 times it has only started on one rotor. But now it is put away for the winter and i most likely will never start that motor again due to the fact that i am building a new one cause i want to make some really power.

just wondering what you guys thought. I have never come across this before.
