Ok, so since the original post, I changed plug wires and performed an oil change. I figured it couldn't hurt since it had been sitting for awhile. Cobwebs all over the undercarriage. When I drained the oil it had fuel mixed with it. Once I added fresh oil and a can of restore. It fired up, running rough at first,but once it blew out the crap fuel it was good to go.

Very strange situation. Would not have guessed it, just came across the solution. Now I know.

Thanks for the input

if you had fuel in the oil there's something wrong. I would keep a close eye on that situation. gasket blown maybe?

My first thought had been that it might need new rings. I did a Google search and found this:



Fuel Found in Oil
Question:
What causes fuel to get into the engine oil and raise the oil level above full on the engine oil dipstick?



Affected Equipment:
Utility Vehicle Models: CX, TS, TH6X4, TX4X2, XUV 620i, HPX 4X4

Answer:
Oil levels may rise as unburned fuel mixes with the oil in the crankcase by traveling along the cylinder wall. Oil dilution from gas in an internal combustion engine is NORMAL operation. The following lists are ways you can help prevent the oil levels from continuing to rise.

- Stay away from operating vehicle in short trips with light engine loads. The reason for this is that the engine oil temperature does not get hot enough to boil-off fuel and moisture in the crankcase. Running the engine at operating temperature and under load for long enough periods of time will allow the fuel to evaporate. NOTE: As ambient air temperature decreases oil dilution will increase because the engine oil is colder.


- Another common denominator for oil dilution is poor fuel quality. Stale gasoline cannot burn fully and ends up in the crankcase. Use only high quality fuels and consume all fuel within a 30 day time-frame. Recommended fuel is 87 octane. Use of fuel stabilizer will extend fuel life (Stabil or Seafoam are acceptable).

- Do not use more than 15% ethanol mix.
