Hi Max, I had pretty much given up on fixing these LM carbs but I just opened the box of primer caps I got from Amazon, I fitted 2 of them onto 24's with PT's I'm building, I used needles that I had put in my reject bin because they flooded and both of these motors fired up with not one problem from the carby. Is it a fluke? no idea but 2 out of 2 without any issue is something I have not been able to achieve previously so I am optomistic that the primer caps may have been my problem all along. I still ran the file through the seat and polished it with Autosol so fingers crossed I might be able to build some 2 strokes again. And another thing I found this morning is that I can start a PT on a 24 without the belt on and not a sign of kickback just using the standard Victa pulley filled with lead. That is 100% the answer. Now I am on the lookout for more lead and pulley This is my latest idea on the diaphragm caps because I was having problems with the idle screw udjuster nuts coming out of the caps .I had tried many ways of glueing them in but nothing really gave me confidence What I have done here is drill the centre of the cap out with a 13mm drill, fill the outside with wet clay and put fibreglass on the inside and then when that has set, dig the clay out and fill the outside with resin. Then I can drill and tap the cap to 6mm and just screw the adjuster screw in. See how they stand up under working conditions.
