Hello from Michigan, I am looking for some help on a 1996 425 magnum 4×4
I picked up. It was sitting in a barn for a few years. It only has 400 miles
on it. Took some time to get it running. It ran good at low speed but missed
and back-fired when I tried to give it more gas. Thought it was a dirty carb.
Took the carb off and cleaned it. replaced spark plug. Checked valve
clearance. Checked cam. Compression is 120 psi. Put carb back on and it
started right up but it back-fired out of the carb as soon as I gave it any
gas. This was with the air cleaner box off. Put the air box on and it runs better but seems to bog out at higher rpm. Also having trouble getting the choke
and throttle cables adjusted right. Any ideas what I am missing? Thanks for any help you can give me.
