I have been trying to get this unknown command engine to run. I took the spark coils off of the ch18 and put them on this engine. I also used the flywheel from the ch18 as well. I disassembled the carb and cleaned all the crud out of it. I used the blower housing from the 18 as well. When I first tried to start it, it would run briefly on carb cleaner. I had to wait a couple of days for a dipstick to arrive so the pulse fuel pump would work and get gas to the carb.


Today when I tried to start it, all it would do is backfire through both the exhaust and carb. It has a good spark and has 175 psi on one cylinder and 155 psi on the 2nd. I'm thinking I have a timing issue.


Can I use the spark coils and flywheel off the ch18 hp on this engine? Why did it run the other day and not today. I did have the anti backfire solenoid energized and on.


Thanks
