Yep, still posting about this TB not starting.

Sympton:

So, any ideas? I am thinking it would be helpful to know:

Thanks. I have turned this new starter over so many times, I am impressed with it. A starter for these things for $70 with shipping was a great buy.

 

At full choke is the plug getting wet?. Another thing to try would be to pull the clutch cover off and spray carb cleaner behind the primary clutch while you are trying to start it. If it goes now, output seal on the crank. Doc

 

that compression seems real low, I would think you should be in the 125s on it. try putting some oil down the cylinder, put the plug back in and try to start, when you have low compression they are always hard to start. The oil will seal the rings and get the compression up. If it starts then you know its time to rebuild.

 

Thanks for the ideas. Yes, it is getting the plug wet with full choke. I will try (1) pull the clutch cover off and spray carb cleaner behind the primary clutch while you are trying to start it [although I have to figure out what you mean by "behind" and (2) putting oil in the cylinder to see if that helps it start.

It is going to be a few days before I can get to it now. [img]i/expressions/face-icon-small-sad.gif[/img]

 

Just a thought,
under your head pipe is a drain for the crank case. It might be backed up with unburned fuel. Take the plug out and turn it over a couple of times if you get fuel out is was vapor locked should start.

 

I agree with sudsy. Maybe see if the headpipe or the muffler is clogged with water or mud. That's what my problem was.

 

he means spray behind the primary(front clutch on enigne)clutch. that is where the crank seals are to see if their leaking.

 

Once again, thanks. I will post and let you know the results of these few things to try as soon as I have an hour to mess with it!!
