Hey guys I posted a message yesterday about a problem I am having with a LA I have recently restored and I promptly got three replys. The engin surges and will not run smooth. One of the replys of coarse was the card. I took it off today and took it apart cleaning every peice of it . I blew a 80 lb. air hose through every port in it and air flowed through everything ok.. I put it back together and on the tractor and started it . It still surges so I retarded the time and then advanced the time and neither helped. It still surges and strugles. I am not new to this stuff but with this one I am lost. HELP.
