First make shure you gettin a good fuel flow. The E-ton flows better in reserve. My 20 mm carb runs great with the 100 main. It has pipe and k&N. My budy has the same set up on his predator 90 and it rund a 100 main. I run straight 112 octain with 45 to 1 maxama Super M oil. Its synthetic.

It would probley be best to contact hetrick they know there products best and im shure they would be glad to help ya.

190 is alot IMO. I never undestood high compression in a CVT machine.
I think mixture should be 32:1
I used the VP fuel with no problem but I didn't like the VP oil at all.
I'm going to go out on a limb here and think you may have a timing issue with the hot and diesel.

I thought the same thing w/timing so I took a look at the plate and it has not been modified or drilled to advance the timing.Is there another way that I don't know about?

[LT80]

I cannot say 100%.The eton I have here has no way to adjust the timing.I plan on slotting the mounting holes.
All I know is my LT motors timing has to be adjusted to run correctly.Altho hot and diesel isnt a problem, they just are not fast w/o the timing advanced a lil.

Have you tried getting in contact w/Hetrick since they are the one's who know the stuff you are running??

Both men above know mini's.
