I chimed in a few weeks ago and had asked about running 100:1 fuel mix to solve fouling problem. As per your suggestions, I changed back to 50:1 and switched to a synth oil (Penzoil Marine was all I could find) and opened the plug gap to 35. <br /><br />Whoaaaa, What a Difference! <br /><br />I am not fouling plugs, the engine idles better and sounds better with the synth oil and new gap. As for the hard starting I was experiencing, I put a new cranking battery in and now the motor starts on the first turn of the key everytime! Darned thing starts better than my car!<br /><br />Thanks for your assistance, your advice was brilliant... As I stated before I am no mechanic and your advice gave me the opportunity to fix the motor without sending it back to the shop!<br /><br />Thank You! Keep up the great work...it is appreciated!
