Potash123 26 #1 Posted January 21, 2017 I bought this second hand after a lady tried to renew the primmer bulb with a hammer and chisel. The carb was mutilated. Sent off for a new replacement which was cheap enough. Would it start !!!! NO. It started with the primmer fuel then cut out straight away. After a bit of head scratching I discovered that the main jet had not been drilled out at the factory. I fitted the old main jet and it started first time and ran great. Thought I would share this with the forum members : ) Don't take anything for granted, I had the same problem with a pilot jet on my Lambretta. Share this post Link to post Share on other sites
Wristpin 400 #2 Posted January 21, 2017 Just out of interest was your replacement a genuine BS item or a pattern part? Share this post Link to post Share on other sites
Potash123 26 #3 Posted January 22, 2017 It was a pattern part, however some parts were in fact brass in lieu of B & S plastic, it was well made apart from the main jet. I was not going to throw a lot of money at an older engine. Share this post Link to post Share on other sites
