Will a PZ19 carb fit a 79cc Predator ??

[michael whiteman]

Is the bolt spacing on a PZ19 the same as the carb studs on a 79cc Predator? or will I have to buy a custom manifold to make it fit. I looked inside my stock carb today and was totally surprised at how small the venturi area is. Adding that to the fact the throttle cable is a real challenge has made me consider a change. Thanks for your wisdom and guidance.

I don't know for sure. If I have some time tomorrow I will take some measurements and look around. If not you can use a welder and some large washers to make an intake manifold.

Thanks Gordy, but not necessary. Got the measurements off the internet and will compare them to the predator. What concerns me is the PZ19 bore is not centered on the bolt holes. I'm sure this will be a mismatch. we can talk about it when you call me. Chance of snow tonight at 31*. Rain and nasty Sunday. m

I'm not sure on the 79cc but for the 196/212 type engines there is an adapter. For my little chopper I made custom intake manifold so I could mount the engine vertical.

The same applies to the 79cc Chainlube. There is a big difference in stud spacing. The bore of the PZ19 is not centered on the studs as one would expect. Wonder what's up with that design? Bottom line: must use an adapter if you plan to do this conversion.

I ordered one, see what happens. Worst case, I'll send it back.

I hope it was this one Robe. Best price I have found so far.

Looks like I'm really cheaping out. Should be here on the 7th. I'll let you know what is up.
Yours has a manifold, that is a nice touch.

You'll need a manifold. The PZ19 is not a direct replacement. Affordable Go-Karts has a DIY kit but it's sold out. You might find one cheaper..........good luck. I felt the kit I found is a better deal price wise for all the pieces it has. You'll need to get them anyway.

Manifold for 19mm Carburetor

10650 This manifold adapts our 19mm carb to a 79cc or 99cc Predator. Solid construction with a curved shape to position the carb flush with the recoil starter and behind the valve cover. The length and shape of this manifold is great for increased low to mid range power. Great setup for the...

This is the one I made for the chopper. I took the carb off to check another engine.
