Partzilla Live Q&A Highlights – Fuel System/Carb Cleaning

ATV Carburetor Problems

Have you experienced a non-replaceable float needle seat on any Honda TRX utility carbs? 

John Talley: Yes … there are so many units out there where that particular seat for the carb is actually pressed in, and unfortunately you cannot replace it. I’ve had a fair amount of luck taking just a Q-tip with a valve grinding compound, taking that in there and lightly trying to massage the seat a little bit. You definitely want to put in a new needle where it has a chance to seal them back up. If it’s really pitted, unfortunately you’re going to have to replace the carb, there’s just no getting around that.  

My quad idles fine, but the second I give it gas it stalls. How can I fix that? 

John Talley: It sounds like your carb is going to need to be cleaned … If it’s been sitting up too long, typically when a carb sits up, it gums up the idle jet. And it doesn’t want to idle, but it’ll take wide-open throttle. Yours is actually doing that in reverse, so that tells me there’s probably something that has been pulled up inside of the main jet … you may have some debris that got into your fuel tank … and it’s lodged on that main jet. So, pull it off the machine, break it down and make sure you clean out that main jet. 

Dirt Bike Carb Cleaning

My dirt bike won’t idle. What do I need to adjust on the carb? The idle screw doesn’t seem to have any effect.  

John Talley: If the idle screw has zero effect on it and it won’t idle, it’s going to be your idle jet, because it’s the smallest jet inside of the carburetor … Some of those things are so small, especially on the mini-bikes, you basically can’t clean them out, but we do sell individual jets, or if you’re really gummed up, we have kits where you can rebuild the carb itself. … if you need help going through a carb clean, we have a video for the Kawasaki KLX 110, where I think I went through that exact procedure.

Motorcycle Fuel Injector Cleaning

My Honda bike has been on standby for 2 years. Any suggestions on servicing it?

John Talley: If it’s been sitting up for two years, you’re going to have to focus on the fuel system … The tank’s going to have to be cleaned out, flushed, and then you’re going to have to go through the fuel system itself … you’re going to have to A.) go through the carburetor or B.) go through the fuel injectors and get them cleaned. And we have videos showing you how to do that using a Motion Pro cleaner … So look at your fuel system, get a fresh battery in there and get some fresh gas, get the fuel system flushed out and go from there.
