This sounds like a fuel supply problem. Probably gum or varnish in the carbureator. Rebuild the carb and it should be fine.

SOURCE: conversion of Yamaha gasoline electricazl generator engine to natural gas

My answer:

Hello Bill:

Here are the site links you'll need to check and/or get info, or buy your adapter kit for your Yami YG4600D Genset conversion kit.

Most likely it's running an 8 or 10HP engine on it now? In any case it's most likely less then 12HP. Not sure what size engine you have, as you didn't say only for the model #? On older Gensets it's harder to track down the HP rated engine is all.

For your Yami YG4600D Genset there you most likely will have your choice of at least 4 adapter kits depending on if you are going to keep gasoline as an option. If you're definitely NOT going to be ever running gasoline again then there are 1 or 2 adapter kits to choose from.

Use the site links below, and then browse whichever area you want as there are many options there. The last link listed takes you through all the different engines by make & model #'s.

I would also shop around locally where you are in LA, as you might be able to get that adapter kit for a lot less then the $227 to $267 they are asking for there at that site.

If you don't see your exact model # (or kit) there call them on their 800 toll free # listed at their site.

Also - if this site doesn't meet your expectations customer service wise at least you will have a starting off point with the wealth of information supplied there!

SOURCE: How can i fix my nixon gasoline generator

Hello, yes this sounds like a small blockage in the carburetor,
My first stem would be undo the carb bowl and clean this out, also make sure the float works ok and shuts the fuel off when in the up posission..
strip and clean the carb but pay attention to the screw what holds the carb on, not sure if this type has small holes in what lets fuel into the engine? also where the screw holds the bowl on, inside there holds another jet, this gets blocked, make sure its clean and you can see through it..
Make sure you usse the correcy size screwdrivers as these brass screws split very easy and can be a pain in the *** to find replacements..
if you need any more assistance send me a msg.. [email protected]

Fuji Micro Generator FJ6200Ri. What is starter Battery Voltage?


At present, the gasoline engine does not have 24 V, diesel engine has 12 V. The ignition of gasoline engines is different from that of diesel engines. Gasoline engines use spark plugs to ignite combustible mixture air to explode for work, so they do not need high speed. A low-power starter does not have to use 24Vstarter battery, while a diesel engine needs a high speed to do its work through a high-pressure spontaneous combustion explosion, such as the excessive volume of a 12V high-power motor. Therefore, the low temperature starting performance of 24V.12V diesel engine is generally used in low power diesel engine, and the application of deceleration starter solves this shortcoming.

3000 watt yamaha generator is really hard to start and when started it stalls under load.


sounds like the carberator needs cleaning and the linkage that makes it open up under load. it works off the flywheel. a lot of generator problems are gas related. water, trash and varnish build up in the carb.

I would look at the honda and yamaha generators. Their small gensets are unbeatable and rugged as they come. Dependable as sunshine.
But, that's just my opinion!
