Hey guys, looking for some help here with my daughter's LT80. A few years ago, LT80 himself turned me onto the carb boiling thing that got this machine running after setting many years.
Now I am dealing with the bike will not start. In the spring (April-ish) I got it out for her to ride and did the usual clean-up and prep. It started and ran all afternoon for her. A couple of weeks later we got it out and she rode again for several hours. Then, the first week-end in June, my riding group was doing their annual motocross track rent day and my daughter wanted to go. So I started to prep her machine, along with mine, the week prior to that event. That is when the LT80 decided to not start.
What I've done:
cleaned/boiled carb
replaced spark plug
removed air filter/intake
remove and inspected reeds
checked key on crank to flywheel
dumped gas tank, put in fresh new gas
re-checked float height
OK, I have spark, it has compression (only cranking with thumb over plug hole- don't have correct adaptor for my compression gauge to measure) and there is gas in the carb. The engine will not even sound like it is firing, even with starting fluid sprayed in the carb or spark plug hole. It acts as if the timing is off, which is why a pulled the cover to check the flywheel key. When cranking, I cannot feel air coming back out of the carb throat nor any moving out the tail pipe. The starter relay clicks when the starter button is pushed and the starter turns the motor with the normal sounding rhythm. The voltage rectifier seems to have power at the correct terminals, just not sure which terminal is which (did not down load that part of the manual).
I'm at a loss here! Anyone have any ideas what I could check or try next?
