[QUOTE="cyclops2, post: 492842, member: 32141"] The smaller the engine ? The more important a CORRECT sized fuel filter is. See if the engine even has a thermostat. Cold engine WILL WILL blacken sparkplug's FAST and cause hard to start engine. I always put in a sparkplug 1 heat range hotter than specified to help with starting & trolling reliability. NEVER ASSUME the spark plug is the correct one !!!!!!!!!!!!!!!!!!!! Find out FOR SURE ! Then buy a new one & carry a new one & sparkplug wrench. Also buy A sparkplug gap checking tool. Check and adjust the thick heavy metal curved part until the gap is correct. .........NEVER touch or bend the center rod of the spark plug. [/QUOTE]
