Who all here ends up being the "fix it" guy?

A 2jet on a 1.5 liter? sounds a big large....

If the metric hardware has 12mm and 14mm heads, it's from Japan

Needs to be a sidedraft per the OP. Use a Harley carb, displacement matches, and they're easy to find.

 

K, after getting closer to the engine, more and more metric appears, so I am sure Mazda is correct on this. Here are pics and dimensions on the intake opening.

 

As said for a side draft think Harley-Davidson. For a down draft carb a Solex off a 1300cc VW should be pretty close. Electric fuel pump.
Check the gas tank real good-propane fork lifts often had the gas tanks used as trash cans in many places.

 

Two flanges cut from 3/8" plate, a 1" schedule 10 ell, a welder, some gasket paper, Solex carb, and a little imagination on throttle linkage-This is good to go.

 

welllll....I did stay in a Holiday Inn Express last night!

 

I can't go up, have issues with hitting the seat deck if I go up any. But the elbow idea also opens up the avenue for like a Ford 8N carb, 4cyl flat head carb but should be pretty close in displacement. I am debating wether to eliminate the belt driven governor, I hate it when politics dictate how fast I can turn my engine...

I think the Harley carb would be out of my price range, as I have been off work for quite some time, just finished some training and should be returning to the workforce soon though...I hate back injuries.

There is no current gas tank on it, will have to find one or fab one up, I wish the propane tank had the saddle mount instead of the vertical mount, I could make a nice tank out of it...just have to get all the propane out of it before I started cutting or grinding. Not into making things go boom that close to me....

 

Quite a few years ago I converted an Onan Generator, a 4 Cyl. from natural gas to run on normal gas. I borrowed a carb off a Kohler 14hp motor just to test the motor then ordered one from Onan. Motor seemed to run OK on small carb but I didn't want to tempt fate and lean out a 65,000 WATT Gen when I needed it most. Good luck.

 

Do a google search for propane tanks. You can buy a new tank for about $130. Used tanks for less.

 

Just do what this guy did



Sorry thought I'd lighten the mood.....thread reminded me of the Hard Hat Hauler

 

Best bet is to find a used forklift supply house.....a wrecking yard for forklifts...they are out there. Tons of Yale, Tow-Motor, Hysters, etc laying around....
And look at varoius units to snag a carb....
I'd be looking into fixing the LP myself....since I do this for a living ....

Let's back up....why do ya wanna convert it anyway? Does it not run? Won't start or idle??? Propane is cheaper than gasoline in my neck of the woods....

 

Man I could be crossing the line here but if it gets you more time to work on the hot rod I did a toyota fork lift with a vw solex they are cheap and it worked well also you will need a fuel pump and a regulator .the linkage was easy not like 6-2s !!

 

I dig this, anyone have a blown hemi they might want to send tothe project... I would have to carry a 250 gallon fuel oil tank around on the forks just to keep gas in it, and then I couldn't go very far

 

I only have 1 tank, and the nearest propane filling station to me is about 20 miles away, the nearest gas station is 2 miles away. I have worked in the small engine industry in the past, and not afraid to tackle the propane system, but there is currently very little wrong with it other than it is 39 years old, and I fear the failure of the unit while I am in the middle of the road, it is necessary for me to enter the street with this forklift quite frequently. I am also concerned about running out of fuel in the road.

I am not worried about fumes as it is only running in the shop when the overhead door is open, and gas systems are easy for me deal with plus, if I am short on cash, I can put a gallon of gas in it instead of having to fill a 30 pound propane cylinder all at once. Someone posted earlier that a spare tank (empty) would cost me about 130, and like it or not, my current finances are not the greatest, and I can convert it for less.

The unit is a 1973, and very handy, changing to gasoline is more of a convenience thing for me, as stated above.

 

Also as stated previously, I am very familiar with the solex and it is a solid fix, but I would have to raise the seat deck to put it on, and I already am nearly rubbing my head on the ROPS. Don't want to have to reengineer the whole thing just to convert it. I think I can put an updraft Ford 8n carb on it and have maybe 50 bucks in the whole conversion...and that is buying a known good carb from a reliable friend.

 

I'm the fix it guy of the family. I guess they think I could do miracles too. I don't mind it too much since they usualy give me good money for beer.

 

The bore size on your drawing is 1.275 inches, or about 32 MM. Don't limit yourself to a Harley sidedraft, as there are millions of motorcycles out there that used 30-32MM carbs on bikes as small as 250 cc's. I just looked on that eVil auction site and found quite a few suitable sidedrafts for around $25. Try to get one from a four stroke bike, so your jetting won't be so far off.

 

Used to use propane tractors to farm with riged up a hose to go between a 35 lb grill type tank and the vapor return on the tractor tank. You could run off the small tank back to refuel it. You could probally even use a Colman lantern bottle.

 

I'm going to take a wild *** guess here but that looks like it could be a Continental z134 gas engine if it is then a good tractor supply should be able to get you parts easily, I had a z134 in my M***ey Ferguson NAPA could get me a lot of parts.Propane engines run much higher compression than gasoline engines do you might only be able to run hitest gas or race if you convert. Forklifts intended for indoor use are supposed to be electric or propane according to OSHA regs

 

Continental z134 was a gas valve in head 4 cylinder used in tractors I had one in A M***ey Ferguson 202 Workbull Industrial tractor.

 

I hope this forklift is going to be used exclusively outside. I say that because even though an LP engine puts out CO (carbon monoxide), a gasoline engine puts out much more and can quickly bring on hypoxemia in enclosed places like garages. The CO bonds to your hemoglobin in your blood creating carboxyhemoglobin or COHb. It acts as a barrier to allowing oxygen into the hemoglobin because the CO bonds really tightly to the hemoglobin, leads to hypoxemia and death.

I'd recommend fixing the LP system; if someone dies, then the extra mileage will seem so insignificant, albeit too late. Your choice of course, I'm just saying, please be careful.

 

Understandable.....
If you have a little room to mount carb directly....look for a Zenith carb off of a Ford LRG-423 or 425 engine. They are an industrial 4 cyl....I've worked on a ton of 'em....simple carbs with a built in fuel shut-off....so you "could" retain the LP and be able to switch to gas.
A company in OR called EC Power Systems carries the parts/rebuild kits for the Zeniths.....hell...prbably has new carbs too.....

 

I wonder if you couldn't line up a few of those on a home-made log manifold and run them on an I-6? Not trying to hi-jack, just wondering.
