1988 LT80 low compression after rebuild

So I've tried just about everything and no luck. I've checked compression, spark, and fuel. Replaced the wiring harness, starter, battery, spark plug, drained cylinder of gas, cleaned carb, replaced carb with one fresh off a running lt80, etc. I am to the point of going to bed thinking about a damn atv...lol the only thing I haven't checked and the last thing I can think of is the timing....could it somehow be off...maybe...we shall find out tomorrow.


im saying the same thing about this chainsaw lol.
im about to say R.I.P.
and get over it and start new:)

there could be summin electrical shorting it out.
starter cranking no matter what lol
