ZreneyfexCarburetor Dual Fuel Carb Conversion Kits Replacemant for Tonco Generator GX200 170F 170G-GX200

I bought this to upgrade my Coleman powermate 3250 to dual fuel. I was hessitant at first, as this part has very little description, or details as to whether it would fit my carb bolt spacing. Its low price compared to other offerings which basically add a throttle body spacer and a huge external regulator (more on that in a bit) . some of those kits require you cut your frame for clearance! That was a no go for me. This one was the same thickness as the original (as measured from flange to flange)Installation was quick, though your efforts may vary, depending on how good the other parts like springs are. Make sure fuel supply is shut off. Run generator until it stops to use up residual gas. Remove the air filter cover, remove the filter. Its a good time to wash/replace if you have some hours on it. Disconnect the crank case tube. get a 10mm socket, and what ever extentions, or swivels you need to work around your frame. On the Coleman powermate 3250, a 3" extension worked well for me. slowly pull the air filter housing forward, while holding the carb back. if your gasket is worn, or damaged, there are some in the kit. Just match it up to the existing holes, as more than 1 type of gasket is included, and you will need a gasket on both sides of the new carb.Remove filter housing. Reach on top, and take a good look around (and some pics) . there will be some governor linkage and a spring. This may be a little different for your generator, but for most generators, you will have to push against the end of that linkage to move it so that the linkage can be disconnect. the spring should pop off easily. if your spring is rusty, it may snap, so be gentle.Put some rags and some cardboard down under the carb. Disconnect the fuel line from the carb. some gas may leak out, but if you followed the steps above, you should get almost nothing. Then pull the carb away from the rest of the intake, and slide off. It could be a little stuck, so it may require a little persuasion to break the initial seal.Ensure there is no prior gasket material left on the intake (i.e. whats left on the engine side after you remove the old carb) and on the air filter housing. Be sure to match up the right replacement gaskets.Look at your old carb and the replacement carb. make sure all the holes line up, and its the right size. Test fit the new choke handle.Installation is really just the reverse. Gasket, carb, hook up spring and cable, choke handle, original gas fuel line, another gasket, then the air filter housing, then install the 2 nuts. Then its the final steps, air filter and air filter housing. then replace the breather tube.Turn back on the fuel, wait a min for the carb bowl to fill up. Turn on the choke, then give the rope a pull. Let it run for a few minutes to see if any fine tuning is needed.With the engine running, use the fuel stop and cut the fuel. let the engine die.you are now ready to test the propane..... or is it natural gas?Here is where things get tricky. The little adjuster has both settings. however there is only one pressure plate. there is a button in the middle of the plate which is for purging air from the lines. if your using propane, you cannot go direct from tank. This little regulator will just open up and vent because the pressure is too high. You must use the standard bbq grill type low pressure regulator to get it down low enough for this regulator to function. If your using propane in your home already, you could tee off the low pressure side, but you may want to consult a qualified plumber for that.if your teeing to the natural gas side of things, anything after the meter should be around 1/4 psi. you should not need any additional regulators.there is a little plastic stick. thats like your fuel adjustment. the knob changes flow for cng or lpg.notes: mine came with zero instructions. maybe its liability reasons, maybe you shouldn't be playing with this if your not at least a tad bit handy.you must also not run the generator with both gas and propane at the same time. its important to shut off the gas and run dry, before switching to propane. bad things may happen if you don't.Overall I like this one much better than a throttle plate design. it doesnt increase size and thus the air filter stays in the same position as it was before, unlike some other kits.

I bought this in order to use my 4,000 Watt Predator generator with natural gas instead of gasoline. I was shocked at the perfect fit of this carb. Installation was a breeze and I had it hooked up to my natural gas line in no time. I find that it fires up best with the choke in the middle position and a couple seconds of priming. My generator has a 3,200 Watt constant rating on gasoline, but I found mine was struggling at 2,500 Watts while on natural gas. I fixed this by slightly drilling out the jet that brings the gas into the carb and successfully ran up to 2,900 Watts with this setup. I also tested this carb's gasoline performance and found it to be perfect. This is an awesome value and a painless install.

Bought it to run my Champion generator off natural gas. The carb was an exact match for the old one on the generator. I bought some adapters to fit a 1/2 inch x 10ft flex natural gas line from the house. The barbed adapter is a fine thread 1/4 inch brass - impossible to find. Only thing I found was a 5/16 flare male to 1/4 male brass adapter to fit the carb. The 5/16 flare side matched the thread size for the carb. Then 1/4 female to 3/8 male. Then a 3/8 to 1/2 inch flare 90 elbow. Started 2nd pull on half choke and then put to run. Won't start on full choke. Only does 80% of the power, about 2500 to 2800 W running on NG. Only gave 4 stars because the plastic top on the regulator was broken. Took the old one off the original carb - fit perfect. It also has the carb seals which was also a good deal. Hopefully this carb lasts.

The product in the questions indicate that the item has a flare connector for connecting the propane. This is not accurate. The connect is not a flare but a hose barb! Two completely different connection types. Also the propane shut off valve is impossible to turn. The product is borderline unusable. There were ZERO instructions with it and I now have to go spend more money to buy a real flare connection to replace the hose barb. The product should clearly state the gas fitting type. This is a relatively useless item.

direct bolt on for any 196 or 212 clone engine. unlike the original gasoline carb, this does not have a fuel shutoff, but uses a bowl drain valve. this makes the switch from gasoline to vapor somewhat problematic, as all the gasoline must be drained from the system first. idle mixture is adjustable. works well on gasoline, was super rich in propane mode. moving the selector halfway between propane and natural gas settings get and suitable a/f ratio.
