Hi all,
brand new to the forum. I've been a triker for awhile, but just recently took on a project. I got a 1985 ATC200S that was running clean....fast....steady....with no problems. THEN.....I ran it out of gas. Booooooo. Hasn't run since. So, here it is in a nutshell, and I am fearing the worst.
Its a 4 stroke motor, and it looks like the carb is relatively new. Very clean.
1. I put brand new gas in it, cranked it 30-40 times, nothing.
2. Getting good blue spark on a new plug.
3. Carb is adjusted to 1.5-2 turns out
4. No rust in the tank
All of those things seem to be in order, now for the tricky parts.
I got it to fire this morning, it ran for about 2 minutes, but only if I held the throttle at about a quarter. Any less and it would sputter. I tried to start it again and intermittently the pull starter seizes up just before exhaust. This is only under compression. If I pull the plug out, it's easy cheesy. I pulled the recoil out, and it works just fine. Note: It did not do this before I ran it out of gas. I may have sucked up some debris from the tank.
The previous owner said that he had not changed the oil in a year or two (didn't ride it much), and that it had been sitting without a lot of care. I changed the oil and cleaned the filters. Lots of sludge. I even took a long swab through the spark plug hole, and was able to pull a tip of gritty black sludge out 2-3 times.
So, I figure that I have a sludged up top end, but it is more like the valve is sticking, and the cam has to be forced over. However it's only when it is under compression. :crazy:
I have heard about filling the crankcase with kerosene and cranking it 25-40 times (repeat until clear fluid drains.) but I am wondering if that will help the top end? I really like this gal, and I will tear the engine apart if needed, but I would like to have her running before our trip to the mountains in 2 weeks. :naughty:
Any advice? Suggestions? I am planning on making this a restoration, but it is going to be a daily rider until I save the money. Of course, I may not have a choice now! :D :twisted: :D :cool: :crazy: :idea: :w00t:
GREAT FORUM GUYS!!! I'll be around.
