Hey yall, as I said in a earlier post the, ignitions are coming of most of may gassers. The 1st victim is this Ryobl 4 cycle. I just got the glow plug adapter made this afternoon and cobbled together this test exhaust. I made the plug adapter from steel this time hoping it will be a heat sink for better idle. Will try the stock carb, but it may not work well as it is a non-adjustable rotary barrel type. If it doesnt work I will go to a WT Walbro, but will have to tap the valve cover as a pulse source and mod the carb for external pulse fitting. Will let yall know if I have any success.
