I am getting a little bit frustrated trying to get my motor to run correctly. I am running out of ideas of things to check. I have a pretty good idea that the problem is in the carb but for the life of me I can not figure it out.
Engine:
This is a Dax bought happy time F80 70cc kit engine.
History:
I have only had this engine for about a week. I got it running monday and have been fiddling with getting the bugs worked out of the bike side and trying to get the engine to run correctly.
When I first installed I had to adjust the forks on the floater down so that gas would not leak from the air intake. After I got that fixed the bike ran ok for about 6 miles but had somewhat low power.
The problem:
The engine will start just fine, but it has very little power. I am topping out at maybe 15mph. The engine sounds like it is bogging pretty badly even on flat roads. Now, after about two blocks the engine just stops. Once it has done this I can get it started but only will run for a couple seconds.
Everything I have done so far:
1. Tried every setting on the choke. It will not run in anything but the all the way down position.
2. Moved the little needle on the throttle to every position on it. No change.
3. Tried to find an air leak. To the best of my ability, I have found no air leaks.
4. Blew out and cleaned every part of the carb I could find. No change.
5. Checked exhaust for any blockages. Did not find any.
6. Rode around the block with the exhaust off. A lot of power, but still engine still died.
7. Checked spark. Getting plenty of spark through the wire, zapped the living !@#$ out of myself on accident.
8. Checked compression. Compression was good.
9. Cried like a little girl. No change.
I am at a loss as to where to go next. I would try another carb but I don't have one and would rather not buy a carb if its not the problem. I am tearing my hair out trying to figure out this problem, I know there is so much fun to be had but instead I am sitting on my front porch learning out to disassemble/reassemble a chinese carburetor in under a minute.
I need suggestions, been trying everything I could find on the forums and so far no luck. If someone thinks I need to check something from the list again go ahead and tell me so, I am new at this and may have goofed something up.
