Engine Rebuild

Instead of posting individual thread like I have been for problems with this motor, I will just post them all into this thread. So I solved the spark issue, new coil I dont know what was wrong with the other one, but this one works so all is good spark wise.

I finished rebuilding the top end finally today, torqued the head and filled it with oil and gas and went to start it, nothing not even a pop. My dad said it would be ok to try a squirt or to of starting fluid, no pop. So I check the spark, all is good. Spark plug sparking all good. gas in the float bowl, check. Compression... 30 lbs . If I remember right in cars, compression should be near 100lbs well I only have 30 mind you it is a small engine but IMO it just doesnt seem right.

So to you guys does my compression seem wrong, or really bad? Could that explain why I wouldnt even get a pop from the motor?

So far I have replaced a piston and rings ect...
Brand new stens carb.
new spark plug
new gaskets except the carb and head gasket ie my theory on bad comp. (if you guys agree compression isnt right, Ill be ordering a new gasket tonight)
new air filter
new gas lines
new to this motor coil
