Which jet outboard for a grizzly 1448?
Make sure that it is looper motor not a crossflow motor.
Loop charge and crossflows are two diffrent types of two stroke engines. The diffrence is the scaveging process. The loop charge motor has a flat top piston that has ports aimed in difffrent directions to corral the main charge of in coming gas into the combuston chamber then out the exhaust port. The cross floww scavenged motor has ports that are mostly aimed staight across the cylinder but the piston it shaped that when the incoming charge hits it the charge is turn up into the combustion chamber and the exhaust slope back down the other side of hte motor out the exhaust ports. The reason the loop charge is better then the crossflow is because the loop charged motors have better port timing for an outboard jet then the crossflows.fender66 said:Make sure that it is looper motor not a crossflow motor.
Okay...now I have to ask. What's a looper or crossflow motor? Never heard of either. Please explain.
