1989 Big Bear 350 4x4 timing

[Likuidsnake]

Hello guys,

I inherited a 89 Big Bear 350 4x4 and it does not run very well. Carb is very dirty, I'm pretty sure it causes the hard idling and stalling. I haven't had time to clean it but just before leaving my garage I decided to check the timing. At TDC, it seems a little off, like less than 1 tooth. Can this also be a cause the hard idling and stalling?

Thanks 

Mike

Pretty sure that is acceptable timing doesnt even look 1/2 tooth off by pics

looks good to me too. check the chain tension and call it good.

I am glad you asked this question. I have the same model at home. Any other suggestions on what could cause it to stall or idle just a little rough? I have noticed it smoking too.

Did you find a solution to your problems?

I think that the timing is ok based on that pic. 

I would really break the carburetor down and clean it good. It has to soak and use a fine piece of wire to clean the jets out.  A piece of a bicycle brake cable works well in the jets. 

Have some air ready to blow out each jet/passageway you clean to make sure the path is open in the carb.

A small can of that air people use for cleaning keyboards is great. 

A lot of people say they cleaned the carb good only to go back and do it again so make sure you do it right the first time. 

The air fuel mixture should be 2-3/4 maybe 2-1/2 turns out from a snug position. 

I think if you start there and see how the bike runs would be a good way to go with a fresh spark plug.  Also lastly make sure the tank is clean and the shutoff valve is clean.
