Can somebody confirm the model and spec of this engine. the 7000 series is a KT engine which would of been a MDI system from the factory. The SV courage twin would of been the engine with the SAM that required the MDI conversion kit. I am wondering if the wrong kit has been installed and the timing if off causing run issues.

Assuming nothing.
Start engine and run at idle then advance to wide open throttle. How does engine run?
Stop engine and disconnect one spark plug wire. Start engine and run at idle then advance to wide open throttle. Does engine run the same or different?
Repeat test with other cylinder. How does engine run? Is there a difference between the cylinders?
When the coils were replaced was there a black module that went with the old coils? There are 2 different flywheels used with the DASI ignition systems. One works with MDI coils one doesn't.

KT735

OK the model number is KT735 now what is the specification number from the tag on the side of the blower housing.

It appears that you have installed a MDI spark advance timing on an engine designed for the CDI fixed timing type ignition system. The problems that everybody is fighting is because the timing of the spark is wrong.

On the upgrade, was there a new flywheel? Sounds like a timing issue a bit.

What are the engine's spec numbers?
Any details on the upgrade?
