Last year I built this engine. I replaced the magneto and installed it backwards. When i corrected it it has yet to start.
Here's what its doing. - It has spark, It has compression, it has gas and I mixed 1 standard small bottle of 2 cycle oil with 1 gallon of gas. the carburetor is getting air and fuel the throttle works.
When I try to start it it sounds like its trying, you hear a clink and exhaust smoke comes out the tail pipe.
Im using a pull starter to continuously try to start it.
I've run these tests. This year I took apart the carburetor and cleaned it out with carburetor cleaner. I reassembled the carburetor and used starter fluid still it only runs through one combustion cycle before not starting. and by that I mean, It gets gas and air into the cylinder and when the piston is at the top the spark ignites and explosion that causes smoke but, that's where it ends. It wont keep running.
Yesterday I rented a compression gauge, and tried to test it but the gauge would never go up. It definitely has compression though. I think the gauge was leaking. If I put my thumb over the spark plug hole and turn the wheel it blows my thumb off. the bike is as hard to pull start as my working lawn mower, when the spark plug is in place.
I checked for spark by grounding the plug and pull starting it. Not only could I see it visually but I got shocked when i was holding it a few times.
In summary. It has the simple things needed to start an engine but it only causes one explosion.
