I switched the petcock over to prime, got it started, and it seemed to run much better. (I only rode it for another 10 minutes though). One other thing. I replaced the stock muffler with a Dyna muffler last week. I am noticing some popping and crackling moving through the gear changes. I know I need to rejet the carb, but could that be adding to or causing the problem? (I had the engine bog down twice before I switched mufflers though...)
Thanks.
If you got gas in it, you got a leaky diaphram. big trouble. you need to replace the petcock or convert to manual.
Until you can get it fixed, clamp off the hose to prevent gas from flowing via the vac line and run in prime.
Gas in the oil is a very bad thing.
