Default orion crf .21 truhe eddition ??

I just got one of these, in good condition and to top it off i had it pinched by "RAY". I HAVE HEARD SOME GOOD AND BAD ABOUT THESE MOTORS BUT DETERMINED TO GIVE IT A RUN.

* I only run twenty percent and it has three shims, should i remove the brass one now or after break-in?

* what will my max temp be (that i wanna stay bellow) ?

* any tuning issues?

* Was told it needs a re-pinch about every four gallons, any truth to that ?

* how do you think my run time would be w/ a jp-4 pipe.
heard these only get about a 8 1/2 minute runtime.

common guys,help a brother out.......
When your kit wont "fire up" and you're askin' for help, let me know (WAY ahead of time) that you put a gasoline and 2-cycle oil mix in the tank!!

That motor needs a 2013 pipe. Tonight we tested a few other pipes and none ran well on this motor.

I have had 2 of these. The first one went 6-8 gallons and the sucked dirt. The other one never ran that great and went maybe 5 gallons.
