Bucking HiJet

[Midway]

Have a 92 Jumbo,coming home last night it would start jumping and bucking when I was going 80/K or so.When I back off,it would smooth out.Stoped at a store,it idled fine so I shut downand went in the store for a minite,it started up ok and didnt act up the rest of the way to the house,even going over 80/K.You think a fuel filter or a coil braking down?Any input would be very helpful.Thanks guys.:confused::):)

here on a wet , cool day (every day) the carb will ice and do that. if you stop and shut it off for a bit it wiil run fine for a few more miles .
make sure the winter / summer valve is set right on the airfilter housing,
mine looks like a wingnut that moves a slide. this lets hot air in.

I fixed it,changed the fuel filter next to the tank and it runs fine now.I found an almost original type filter with the 90% inlet and fits in the same holder clip.It is a WIX 33053 fuel filter. Hope this helps someone.
