hey guys i inherited my reble from my father who passed. its got about 8k miles. so my question is this. its got an oil leak then started to have issues idling. ive already replaced the seal on the left side (cant remember the exact name but its on the spindle that has the mag on) and replaced the gaskets to no avail. when pulling some of the engine apart i smelled fuel in the oil. can you awesome people point me in a direction as i only have experience with car/truck engines so this is all a bit new to me.
