Robin 5hp

A buddy of mine has a robin 5hp motor in a snow mobile for his kids. He says it is surging at idle and not coming up to full rpm. Sound like he has a main jet partially clogged.What do you guys think. Any thing else I should look for?

WAG   
If I remember right had that type of motor in a go kart.  Used to get clogged up from setting and running ethanol gas.  I used to have to take apart clean the clear jelled like junk out and all would be good again.

I have a 10hp Robin/Subaru engine in my generator. And last year it had accumulated so much water in the fuel system... That it litterally froze wverything up.  But... What a very nice running engine. Very close to a Honda... And very easy to work on.  I always have Seafoam on hand now.  Keep it in all my machine... Its magic !
