i know you are bashing your head against the wall. im not that computer literate. I type in my model # 10a902 then engine model is a 2072
then i got a parts list, shows parts in diagrams but not location fitting. has the parts blown apart look. I put the carby and or spring code in and it links to a price and buy it now feature. there is not exact diagram with the spring and carby assembled. If you can locate it for me and copy and paste the link then i cna directly go to it. Sorry it just takes practice.
