To start with get #1 on compression stroke and see where the rotor in the mag points. Remember on ly 2 firing orders for 4 cylinder engine. 1-2-4-3 or 1-3-4-2. So if you get #1 right #4 will be straight across from it. 2 and 3 will be in between. If it misses turn those 2 around. I will look here in the morning if no one answers you. J.

Firing order is 1-2-4-3. Mag rotor rotation should be clockwise when viewed from the rear. #1 is in front. All 4 cylinder 4 stroke engines have 1 & 4 , then 2 & 3 as paired cylinders.
