?
I think so. on the compression stroke. When I crank the bike over when it goes to the exhaust up stroke its really hard to push kick starter past that point. On the "compression" stroke it shouldnt be hard to push the kick start thru that stroke, right. So I want to be TDC on the compression strike?
I am using the instructions for setting valves from a previous stroke. My bike had over head cam. Basically am i at the right TDC when the piston is at its highest point during compression stroke.? Michael A

I'm not convinced that your carb issue is behind you. I've never used Chem-Dip, but I wouldn't trust it to remove all debris and shellac from the jets, particulary emulsion tubes. Did you mechanically clean the jets as was recommended by knothead? I've used staples that I've straightened to clean jet passages; they're typically small enough, and they bend easily rather than damaging a brass jet.

oops
I think I adjusted my valves wrong. I think I adjusted valve gaps when I was on the exhaust up stroke. That would cause bike to run bad right? I will re-adjust valves with TDC on Compression stroke.
I believe I did a good job on the carb. The Chem Dip is suppose to be the strongest carb solvent I think. Its just really poisonous though. After the chem dip I sprayed it all good with compressed air thru all openings. My float bowl is good, not stuck. I am wondering if I need to adjust that Pilot screw to allow richer mixture or not. I did get tons of mud and water in Air Box so some of the much must have got in the carb real good. When I drained oil, before I cleaned carb and air filter, it looked like there was little water in it also but I got good oil in there now. I'll adjust valves tonight and keep you all updated. I am just trying to stay motivated. I have my Xmoto 250cc, DB27 dirt bike and 250cc Chinese buggy all down. : ) I will fix them though. I'll never give up. Thanks for all the help dudes. I'll help other poor souls. Michael A

one more thing
I might have my wiring to my battery kind of funky. One of the first things that broke on my bike was the end of the wires to the battery snapped off and I had to redo them but the bike started fine after that. I have a ground wire on my bike frame.
I work on my bike 6 days straight after work. I'm getting worn down. Michael A

After all of that, my new used Honda had a stripped spark plug hole. Bummer. Oh well, when I fix the threads I'll be able to lap the valves and change the valve stem seals. It'll be awesome when it's done.

can't adjust valves
When I tried to adjust valves I couldn't loosen the stud nut to slide the .05mm fueller gauge under the valve on the back of my engine. I assume its the Intake Valve.
But I could loosen the stud nut on the valve on the front of the engine and put the .08mm fueller gauge under it no problem. I am getting confused about where the correct TDC is on my bike when I can't get the stud nut to open on the Intake Valve side. Why can't I get the fuller gauge to go under the intake valve stud nut , or the valve in back of engine??? Is the valve broken or something?? Is it jammed shut?? Anyways, any suggestions or solutions would be greatly appreciated. The company I purchased the bike from, PowerSportsMax.com, finally had a tech call me to help me on my bike. I notified them several week ago. I am afraid to call them because they wouldn't honor their warranty on parts because of my "excessive riding". So, I am confused why one of their mechanics is calling me. They make me feel bad. My experience with these Chinese bike dealers is very poor when it comes to tech support. I've had simuliar experience with my Chinese 250cc Dune Buggy. Michael A

valve adjust 3
I re-read the How to Adjust Valves Post by red2003. Makes a little more sense now how to determine the "Compression" Stroke TDC.
"You need to be on the COMPRESSION stroke to set the valves, so you need to determine which stroke you are locating top dead center for. The easiest way to do this is to remove the sparkplug and "stick your finger in the plug hole to plug it off." Rotate the engine on the kickstarter until" your finger is forced out by the compression", you are now on the compression stroke, look for the "T" and you're ready to adjust the valves." Think I can do this. Michael A

I agree
My 78 year old back yard mechanic dad convinced me to buy a carb cleaning set of carb cleaning wires and clean my carb out old school style. Thanks alot dude. i dont know what else is more difficult, working on Network Servers or these dirt bikes.
