lt230 wont start

[suzuki230]

The quad is 1986 suzuki lt230. i just put the timing chain back on it and set the timing using the manual and i tried to start it. it will sit there and turn over but wont start. i checked to see if getting spark which it is. (blue). at this stand point i dont know wat to try next. need all the help i can get right now. thanks

is there fuel in the carb? maybe a shot of starting fluid...

The 4 stroke is a simple system of suck-squeeze-bang-blow. that's all it does. when you turn it over you should get a push of air from the exhaust side and a suction of air from the intake side. you can test with the palm of your hand.

the valves must be closing and the cam timing correct for this to happen of course.

cam timing can be tricky and frustrating and it has to be exactly right.

take the spark plug out and put your thumb over the hole. turn the engine over- if it pushes your thumb off then the valves are closing.

Wouldn't hurt to check the shear key on the flywheel either, if it is broken, you will get spark, just not at the right time.
