Hi, I have just reconditioned and cleaned my carby, decompression valve and cleaned out the fuel tank on my Victa Mustang Series70, 2 Stroke, Mark 4 lawnmower and it started first go however it stopped after about 30 mins and would not start again. Can anyone out there provide me any advice on what I can do next to get my Victa Mustang to start and run more reliably? Also when I replaced the diaphragm in the carby it only had a small circlip washer holding the diaphragm to the end of the poppet valve (see photo) whereas the videos I have watched show that there should be a larger metallic diaphragm retaining plate! Would it be advisable for me to replace the small circlip with the larger metallic diaphragm retaining plate to provide better support to the rubber diaphragm? Any advice or help would be greatly appreciated. Lecky23
