Sticky Throttle - possible fixes?

[stephenw22]

So, the throttle has been sticking on the Hornet during snowy (blizzard-y)weather. At first, I figured it was the throttle cable, but there aren't any problems with it. Instead, it's the carburetor that's sticking. I've been brainstorming about it last night, and these are the possible fixes:

 

1. Lube up the carb with some wd-40 (temporarily) and then with some dry graphite or other non-gummy lube later on, once the weather warms up.

 

2. Mount a strong(er) return spring on the carburetor to really yank it shut. As an added benefit, this might help me go easier on the gas pedal.

 

Any other suggestions out there? None of my other subes (carb'ed or not) have had this problem before. Probably, because they had already been through 10 or 15 winters when I got them...

my new RX was sticking too but it was at the pivoit for the pedal itself.

 

a little Triflo and its working fine.

A stronger spring would help with return, and if you make it heavy enough, you might save a lot of gas. You might want to use carb cleaner or brake parts cleaner rather than WD-40, because if the throttle plate is sticking it's likely to be varnish buildup on the throttle shaft. Also, as RallyRuss has said, check the other things like your pedal to make sure it's not something simple.

I know it's at the carb because I've checked under the hood and that's what is sticking. The pedal moves fine, and the cable glides smoothly.

 

It's a fairly new carb from what I understand, so varnish shouldn't be an issue - the WD-40 will have evaporated by the time anything has a chance to stick to it.

 

It's a goofy problem though. The cable was fine at 30F and -20F, but when it's 10F and snowy, things are sticking.

 

I'm leaning towards an extra spring on the throttle.
