I am not paying to do the repair, I do them myself, I only pay for part when I need them, example: I have an ariens snowblower that needed a valve job(leaky exhaust valve.) I took the old one out, brought them to that repair shop,asked them if they needed to be replaced or just machined, guy said they are done, I bought 2 valve, installed them myself, but I cannot test them because of a rookie mistake, I forgot to take picture of the linkage and now I am lost, but I got a planif your paying a shop to repair stuff for you then you should probably pass and just buy new. i really don't see you buying too many good 10hp engines for $20 but good deals to pop up occasionally but then again most of them good deals still usually require a $20 carb kit. i kind of understand why more people are willing to just throw a carb at things for $20-30 instead of messing with things. most of the newer carbs are such a pain to get working right because of tight emissions standards. i was tired of messing with the one on my neighbors ariens snowblower and paid the $35 for a new one. his machine sounded so much better afterwords. i don't think his machine had ever run this good even when new. i know someone else with an ariens machine who may be getting the same thing done next winter because i am done with that carb also.
