sorry man ,, we have all been in the field ,,, you will get a lot of responses come winter ,,, have you drained the water trap under the tank ,and the water out of the filters ???,, that needs to be done once a week ,..ok ,,.., has the intake manifold air breather been left open to the elements and varmints ???? if so by all means ,, give it a good going over ,,, what is the history of this 630?
, when did this 630 last run ?
/, and why was it parkled ? those clues will help diagnose the next step ,,. in all honesty , if you have fuel to injectors , and it is pulling air ,, it should run ,, however ,,, if timing is off , or someone has tinkered with the fuel pump ECT ,, lots of things could be wrong . to make this 630 or any engine not run ,,, if it will start and keep running , and the fuel is old try some lucas fuel and upper cyl ,. lubricate to help clear things up... also a qt of atf per 5 gallon fuel worx wonders ...btw ,, I have been running a 630 gasser today and this summer on a 1190 ihc haybine ,,. been hookt together for a month now ...
