Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
can you give me a general instruction of how to get at the valves and adjust them?
have I missed the answer somehow ro my reply?
First step is to remove your spark plugs,and valve covers. You will need a few open end wrenches and a flat type feeler gage ( set at .004 ) and maybe a "torx" or Allen set It is probably easiest to see it done so I'm sending you a link to a video that I like. This is for a single cylinder, just repeat for a twin. I'm available if you need more detailed instruction even after you give me a rating. Let me know how it goes!
the valves were properly set at .004 but engine still backfires out of the carburator. What could cause that?
It seems to be smoking out the right valve cover when rhe engine gets hot
