Thanks for the reply. I checked the compression again and it is more like 142. I removed the air filter, and put a little mixed fuel in the carb inlet, and still nothing. It seems to me that is it was a clogged carb, putting fuel into the card should at least make it pop. The plug is sparking and I also tried a plug from a working blower. It has not even popped once. I also checked the exhaust screen - relatively clean. Are there other screens deeper in the muffler that could be clogged? This one has me baffled.
