First weber failure

[splatterdog]

The webered 84 I gave to a friend barely made it back from his farm today. 2 hours of full throttle to get home. He knocked the muffler off at the farm too! Sounded real bad

Found the plugs thoroughly blackened. Plenty of black smoke when it rolled up too. Air cleaner well oiled. Choke not stuck. Didn't look good at first. Did a compression check since the plugs were out- 200psi accross the board at 250k miles. Good crosshatch still in the bores too. Not bad for a quarter million on the clock.

Peered down into the carb including the gap where the inside of the bowl can be seen. Saw the craziest thing. The primary main jet had backed out and could be seen lying on the floor of the bowl. Talk about overjetted! Put jet back in and changed oil. Good to go!

So if your webered car will idle OK but only run poorly and only wide open with lots of black smoke, check the main jets.

wonder how that happened. Someone replacing jets forgot to tighten it? If not perhaps some loc-tight is in order.

Paying attention here. Adding to list of occasional checks.

This one was out of box, never touched it till now, a good 60k later. Secondary main jet was all the way in but not tight also. No loctite either. Quick repair while still on the car and wet. Only takes about 5 minutes to get to the main jets on a weber.

This is probably due to my friends horrible vehicle luck. I was hoping my old T4 would break it. I'd give the body 2-3 years max before structural integrity is an issue. The rest, who knows under his helm. The 84 has proven to be a true survivor. Metal loaded gear oil when bought at 160k, needed a weber way before I got it, 2 real good thermal events not counting the napkins in the dash fire complete with flaming balls coming out the dash vents. Still drives awesome(for a T4)

I do know that I get first pickins on the carcass!

If there is a lesson to be learned here, I would suggest looking down into the bowl at every air filter service. The jets can be clearly seen with a penlight.
