Start with #67 jet then let us know how it is.

Stock is #70 jet AFAIK

I have a 7.5 jet in now. The kit I ordered came with 6-8.5. I was still running my fuel at break in because I was told like 300 miles to do that, not knowing it was only suppose to be for the first two tanks. I just started using leas oil yesterday. Now i believe it's 4 stroking. Also when I pull the choke in it revs extremly high then goes to a low idle... Any suggestions??

I do not know what a 7.5 jet is. You mean a #75 jet?

I am watching an eagle as it is flying right now, so beautiful.

4.5 ounces of oil per gallon of gasoline.
I use Valvoline 2 stroke oil.

I do not have a choke so i cannot help you there.


Keep us posted please

This is the kit I bought... Maybe I bought the wrong one but I didnt want to wait for others that i looked at. The package just had a "7.5" on it..

Ya 7.5 should actually be 75, seeing the needle kit you got doesn't have a 69 or 67 you'll have to use the 65.

 

[Dserna]

Yeah it was a 75. I couldnt get the 65 on and was worried about cross threading so I had to use the 70. It isnt 4 stroking a whole lot at top speed- little to none, but does a bit when accelerating. Im going to get a new jet kit however, as well as a new intake manifold. It 4 strokes a lot with out the boost bottle- I have an on off switch, so i think im going to keep it. But I am going to do as told with the head and copper head gasket, as well as cleaning up the ports. If you have any thoughts I appreciate the input.
Thank you!

And I ment to say clutch earlier not choke..

 

[Chainlube]

I've never seen any hard evidence that a boost bottle is beneficial, all the reports are, hmmm. Nobody says yay or nay.
