I have a 200E that was left in a barn for 4 years with gas and what-not still in it, I took the carb off and took it all apart it was filthy I have it soaking in mineral spirits, I am going to pick up a new sparkplug and see if it will run with the carb cleaned and some new gas, Can you think of anything else it needs to run? Im hoping it will fire right up it has spark but i want to put a new sparkplug in it anyways.aparently it ran when it was parked 4 years ago.
