My new powerhead has about 1 full (120 gallons) tank of 25:1 mix through it and all was well with the break-in.(we mixed 50:1 in the tank along with the motors 50:1 mix) On the 2nd tank of gas, there is still some oil in the gas tank so it is probably running about 35:1. Now, when i run for an extended period of time, then stop and kill engine for say 10min or longer....it is real hard to start again or keep it running. It wants to sputter and die. If you full throttle it and run for awhile (5min +) it is then back to normal. I am changing the spark plugs today and noticed they were a little dirty. Could this have been my problem? Is it normal when running it rich to need to change plugs that quickly, and should i change anything else??? And would fouled plugs have caused my symtoms? It is a 2000 Merc 200hp carbed. Thanks.
