C60X running not as well as it should....

Sounds like fuel starvation to me Warren, although spark breakdown can produce similar symptoms. Best way to diagnose is to play with the choke while driving. If it responds to choke under load you know it's a fuel problem rather than spark. In this case I suspect you may have sucked up some water into the small inline fuel filter. They stop water getting to the carby but the wet paper element restricts fuel flow. It's certainly the first thing to replace as you say, and you may also need to drain the tank to prevent recurrence. Often there's quite a bit of water swilling around the bottom, which accumulates through condensation over time, esp. if the tank is near empty. Alternatively you can run it without a fuel filter, which allows any water to pass harmlessly through the carby. Fuel filters are quite unnecessary in my experience, provided of course the fuel tanks are free of rust flakes and wasps nests!

I agree with Phil re valve clearance adjustment, which is generally routine with a major tune up like this. Anyway good luck with it all and I'm sure there's no major problem.

Hi All

Here are some photos of the inline filter on my Pat 12 C60L that started burping and farting recently when under full throttle on long up grades.

First two photos are with the regular fuel pump sucking fuel the last is with the electric fuel pump at the tank running note what happened to the length of the filter element.

Yes replacing the filter did solve the problem.

Phil thanks so much for the tip - I'm heading in to pick up new fuel filters as we speak. When I get back I'll do an autopsy on the old filter and post a photo. I think my filter was personally installed by King George VI when the truck was built. Next step - air cleaner...and then onto the ignition system... wish me luck...
