hi all, iv'e got a victa mower engine and it has a lever start, i dont like it cause it keeps breaking and i have to always reset the tiny spring, so i pull a pull start chord but there is way too much compression and have already snapped 2 new cords on first pull, so i dought a decompression valve and fitted it but there nowhere on the (obviously aftermarket ) carby to connect the decompression valve pipe ....... im imagining i have to drill a hole into the carby somewhere has anyone got any tips ? thanks in advance
