I work at a hobby shop. Customer brought in a rampage mt in a brand new 30.5 that wont start. Getting fire, getting fuel. Seems strange but compression feels low, might just be me, used to being able to carry my tt by the compression in the pullstart on my 26.9 top end. Customer said hes running regular 87 octane fuel. Could this be too low octane? The engine has never started.
