Hello,I have a 1990 225 yamaha that I can't seem to get the choke to work. I have inspected the diaframs, and it is o.k., cleaned all the leads to it I could find,still not working. Is there i am missing? I admit I do not have a manual,maybe someone has one on pdf? Anyway, I stuck with no choke,can anyone point me in the right direction,I would apprectate it.Thanks!:

you should have two soliniods on the upper pump labled A and B.
the push to choke function has no affect on that motor if you have A and B solinoids.
cold start enrichment is based on a signal from the engine temp sensor and controlled by the ECU.

THANK YOU,rodbolt! So I am to understand that choking is not needed on this motor.Just turn the key and your good to go? Thanks again!
