I have a 1972 1755 gasser. I changed over the points to electronic ignition. I am still having problems with it running and starting correctly. Can someone tell me if there is supposed to a vacuum arm that comes out of the side of the distributor into the vacuum chamber. I think I am explaining this correctly but if someone wants to take a stab a helping please let me know. 
Other than this I really like the tractor.

Thanks  again
