Did someone take the time to add an inline fuel filter? Could be clogged. It's a '84 with a steel tank, after all.

Have you tried running it with the filler cap open?

Amber Lamps · 06-23-2009, 04:03 PM

I was thinking that too... Also see if the plug was "wet" when he took it out. Maybe his spark is weak.

Maybe getting too much fuel...

I do not believe there is an inline fuel filter, I will double check

Tigger, the plug is not wet so I don't think that's it....

I got the seafoam and am soaking now....wish I had an air compressor to blow them out with!

Brake cleaner with a straw?

Negative Ghost Rider.

Brake cleaner, as the name implies, is for cleaning brakes. This is why it has the words BRAKE CLEANER stamped on the can, in big fucking letters.

Do not spray that shit in your carbs. It eats seals, o-rings and plastic bits, like M&M's in a microwave.

I would use CARB CLEANER, instead.

I would also buy the 15 buck rebuilt kit, since that thing is ancient.

Alright, I did get some carb cleaner in a can with a straw and sprayed each yet out. The carb cleaner was coming out just fine so i don't believe any of the jets are clogged.

If I hold the throttle open the motor will keep running but if I let off it dies. Running like major poopage.

J/C, the internals, o-rings and float are all in excellent condition. This is not the original carb...

The guys on Planet Mini think it could be the points and condensor (part of the alternator, I think). I called the local shop and its about $45 and they don't have them in stock.

Damnit.

Also what PC said about trying it with the gas cap open. Plus, is there any chance that carb seal is letting in air? What about the points? Oops I got a call mid post and now I see this was covered. FTR I meant using whatever to clean the JETS not the entire carb, I'm not a total idiot!

Kaneman · 06-23-2009, 05:17 PM

I doubt it, the little plastic piece that goes between the carb and the intake is in excellent condition as are the two rubber gaskets.

Try it with the gas cap open?
