Another tip : if you have a little pen torch like used for soldering you can heat the area to try and cook out any oil that has soaked into case . For better adhesion

Pretty sure yes . But not 100% . Reach out to cpd in Texas and ask them . They used to be the Gasgas distributors and were parts suppliers . He still supplies parts
