first of all since you are still awake this late at night we will hit one issue at a time. Are you very mechanically inclined???? This will help me on answering your no start prob.

nevermind I guess you went to bed....BR>1) check to see if you are getting gas to the carb(remove the fuel line from the tank to the carb)
2) see if you have spark(remove spark plug, set the plug so it will ground out, and pull start it, look for spark)
3) do a compression check(install a compression tester in the plug hole and pull start it)
Then tell us what you come up with

I do not know the shift pattern on a 70 but someone on here will help you with that

after you try to start it a bit....remove the plug and see if it is wet with fuel.

Shift pattern on an ATC 70 is ALL DOWN. I had one from when I was 7 to 13 yrs old. FUN FUN FUN! Then I got a 200. woo hoo! front suspension! Boy, was that nice after my 70.

Save wear on your pull starter, just put it in second gear (two down-pushes on the shifter from N), then tow it around with something like your quad or truck. That way you're not wearing out the dogs and cogs in your recoil.
Not something I'd do all day, but it's a good way to do troubleshooting on-the-fly. You can be screwing with the choke/throttle/mixture while the engine is turning over.

Oh crap, never mind. I didn't even see the 8th or so post in this string. I'd check the decompression lever/valve. Is it set properly? If it's not connected, you're better off, even though it's harder to pull. With only 70ccs, though... how hard could it be?
If it's set to decompress too much, then your compression is suffering as soon as you pull on the starter. I think a little black cable comes off the top of the recoil at an angle and goes forward (???). Just disconnect the cable at the right side of the head, and see where that gets you.
It's been a while, so I might be a little off on some of my locations...

I just got a 85' honda atc 70 and I have clue how the shifting pattern goes on this thing and I fixed the pull start on it and I pull and pull and it won't start.
Please help!!!

Posted by: littlethingscangofast

Posted by: littlethingscangofast
