Robert, this reminds me of trying to diagnose a problem over the phone. We're always getting people calling us, asking what the problem is < chuckle >
Anyway, if you're going to have it repaired, have the dealer order the short block for this machine rather than all the individual parts. That's a much better way to go.
If you have the BIS carb the part # for the short block is 4137-020-0201.
If you have the adjustable carb, the part # is 4137-020-0202.
The MSRP for each is $97.95. The labor should also be a little less if you went this way.
Hope this helps
