I purchased the 775EX or HU 775H mower. I recently experienced heavy white smoke and oil coming out of the muffler area. There was plenty of oil in the system. I have tried to research suggestions and I have read if the unit was turned on its side or has been in the rain (heavy soaking) this can occur. The suggestion was to remove the muffler, clean it out and then replace the oil completely. Do you agee? Would this be the cause for teh smoke and oil from muffler? What do you suggest to remedy the situation. Please advise, thanks!
