Answer
Wayne,

I volunteer my time with AllExperts. It's my goal to be helpful. I allow ratings to help you make a better choice on selecting an expert. I respect your rating.

It wasn't my intention to be rude. I was hoping that you would reply with a corrected narrative description. Imagine my surprise when I read your question. : )

It's important to be thorough and include as many details as possible in the narrative description. I can only go on the information that I receive. I'm not there to perform tests for accurate diagnosis.

Volunteering can be nutty at times. For example, a guy with no experience cleans his carbs and tells me, "I know it ain't the carbs, I cleaned them." That's where my work starts, respectfully.

I return tech information files by email. There was no email address with your question as requested and explained in my instructions.

If interested, reply with your email addy. Also, try the imformation below.

Do you have a copy of the service manual?


Check valve clearances.

Check cylinder compression.

Check for vacuum leaks.

Check throttle cables for proper routing and operation.


Respectfully,
Mark Shively
