so before i premix gas,i should unhook this pump that pumps oil to the cumbustion chamber?i forgot what this pump is called too,haha. if i purchased a hayes manual,and had a basic understanding of how to keep my head out of my ***,would this be a procedure someone could do on there own?

You dont need a haynes. Waste of money IMO. You can download and print the FSM @ fc3s.org for free. Way better than the haynes manual.

All you do is remove the 2 bolts holding the OMP on, take off the rod thats attached to the tb, take off the OMP, unbolt the 4 injectors. Now take 4 stubby bolts and put them in the oil injector holes. Take a 1/4in thick plate of aluminum and trace the OMP onto it. Take a hack saw and cut the shape out. Drill 2 holes in it for the OMP studs and throw a some rtv sealant on it and bolt it in place of the OMP. Now throw some 2stroke in ur gas tank.

What are you asking bro?

YOu do not need to disable the OMP and oil injection system to pre-mix but I did since I broke the lines. I just made a block-off plate out of some steel and blocked off the oil injectors and run full pre-mix.

I read the link and it said you could use premix without removing your omp... something about a 400:1 ratio. is this a good idea and how much do I put in if it is?

Cory Simpson

not a 400:1 ratio use 1 once of 2-stroke oil for every gallon of gas in your tank, your tank hold 16.6 gallons. just dump 18-20 oz. of 2-stroke oil in to your tank before you full the tank then fill it and it will mix it's self
