DADS50 Thanks for your detail response, and thanks to everyone. Mine is definately a full pressure later model 235, so I have to go with intake valves and distributor position to start with. I tried last night, I might have timing issue in addition when I rebuilt the carb, it is leaking from the sides. may be now I am have gas starvation. I pour through the top hole still leaks out. I have to fix that problem. It was not leaking before someone said the accelarator spring and rod conneting side they use lead filler to fill probably JBWeld might work they said. I have to try that now
Thanks to everyone .
