snowhound 103 #1 Posted December 15, 2013 My son's C105 won't start it has spark and is getting gas. When cranked over there is exhaust from but it doesn't sound like it is firing. My guess is a bad or hung up valve, does that sound reasonable? Thanks for looking, Ed (Snowhound) Share this post Link to post Share on other sites
953 nut 52,132 #2 Posted December 15, 2013 Pull the plug and do a down and dirty compression test, put your thumb over the plug hole and crank it over. Presuming you have som compression put in a new Champion H-10 and start it up. Share this post Link to post Share on other sites
