engine will not run

[fescue101]

today i found an air leak buy the flywheel so i bought a sealed bearing and took the whole engine apart. then put it back together and the compresion seems very good almost to good and it would not start unless i gave it alot of gas.it also takes the gas in the line alot longer to reach the carb when i prime it and sucks back into the tank when i stop holding the ez start button. what is going on please help? revo 3.3 buy the way

Clogged or leaky fuel/pressure lines perhaps? Clogged fuel filter either inline or in tank? More air leaks, perhaps on motor and need of being sealed (on my list of things to do). I'm still new to hobby so these are slightly educated guesses.

I've had the same, just stripped and rebuilt the card, cleaning with nitro or break cleaner and it went away
