He still stands that is was bad fuel to high alcohol (13%+) Knowing that is what he believes I stopped at the local station I buy my fuel at and bought a gallon for him to test. And it came back 100% gasoline. Yea me! I asked him why Dolmar made him pay for have of the repair and he said Dolmar didn’t make him do it he offered if they would share the cost of the repair because he said it was not covered under warranty.
The tech was pretty cool went back a got a blower from the shop and showed me the same fuel test and it did come in around 10-12% and made a milking white color also, said that’s how mine looked when they tested it. Didn’t want to get into it so I chose not to remind them that it was there fuel they put in my saw when they did the test. Asked if I could have the old parts and they said no they needed them to get paid by Dolmar but had no problem showing them to me. The top of the piston looked normal light carbon deposits covering the entire surface. The damage we saw from the initial pictures went from the very top edge of the piston to the very bottom of the skirt and almost 180 degrees on the other side there was more damage of the same type but not as much. The cylinder mirrored the piston. I am no saw mechanic but I think the saw ingested something. It just seems to me that if it was a fuel issue why wouldn’t the entire piston be damaged? Why just two separate places?
Anyways seeing how they tested the fuel I came home and made my own homemade tester from a cigar tube and tested the now 2 ½ month old fuel I had been using in the saw. Look at the results its shows no alcohol but it almost turned into a white gel substance any thoughts?
