I DONT KNOW WHT IS WRONG WITH MY JATO. I HAVE A OS 21RG ENGINE ON IT. WHEN I START THE ENGINE IT CUTS OFF AFTER 2-3MIN. THE COMPRESSION IS OK, BUT DOES ISNT HARD LIKE BEFORE. I HAVE COMPLETED 2 GALLONS ATLEAST. I AM NOT SURE ABOUT WHETHER IT IS THE TUNING PROBLEM OR MAYBE THE SETTING OF THE TROTTLE TRIP.

SOMEONE ANY IDEA WHAT THE PROBLEM COULD BE?
