I have a 2003 gti le rfi and it will not start after the initial cranking. If it doesn't start right away I have to remove the plugs and dry everything out. I noticed that there is a gas/oil substance on the inside of the air intake cover. Is this normal or do I need to replace the reed valves? It ran fine two days ago and now it is dead. Thank you in advance. I am new here so thank you and I am glad to be apart of this community.
