Picked up this trke .

[dustrunner]

227784 It has a pretty blue spark, new plug , gas sprinkled in plug hole but it still wont start... has 95 # of compression.... seems like it should fire ...and ideas ?

[81ATC185S]

95 is way too low. It should have like 175.

[atc007]

Adjust the valves.

[hawaiirider]

yep 95 is low on a 2 stroke, a 4 stroke prob wont run at all or be very weak

in freshman yr we had a old xr75 that ran out of compression, no $ to fix it so we put half lucas oil in the motor, drilled the jets all the way out to run alcohol, and pulled it behind the truck for about 5 minutes. when we just about gave up it came back to life in a huge wheelie with flames shooting out the exhaust. it ran like that for a few months before it stuck a ring.

don't forget to clean the carb.

[yaegerb]

will it pop on ether (starting fluid) or if you pour a spoofull of gas down the sparkplug hole? If not, then your timing is off. If it will pop then its carb related.

Make sure no rodents are residing in the exhaust or airbox.

[dustrunner]

This model apparently doesn't come with an air box. THE VALVES ARE OPENING AND CLOSING. just gotta figure out the adjustments .

.08mm or .003 inches

My money is on timing.

[dustrunner]

The exhaust valve was a tad TIGHT but now both set at .003 but still wont start ....the advance on the cam isn't working. no cam cover on it plus sat outside...gonna try get that lubed up ...

[dustrunner]

Got the advance freed up...Compression is now at 130 # BUT IT STILL WONT FART .

[dustrunner]

Thanks everyone for all the help...Gonna pull the exhaust of in am...Cant stand to look at it anymore today ...Why I keep buying these thing I WILL NEVER KNOW .

[dustrunner]

Welp , pulled muffler...header looks clear....soaked and cleaned carb .... had a few farts but nothing else... would a valve job save it ? :wondering

[yaegerb]

Have you checked to ensure you timing is correct? If not read article below and get motor in time.
