Default Repair or buy new Marder?

OK looks like the seller is not interested in my slightly duff Marder (like expecting to pay £50 for everything!) Anyway I've got that Marder with..

Body Shell mint
Body Shell above average condition
Mint standard spoiler
Mint Poly Spoiler
Everything else in the Marder nothing damaged, except for wonky engine
Dual Hitec MG servos for steering
Hitec MG servo for brake/throttle
Chassis in good condition, minor scratchs, no dents
Shocks/suspension in good condition, no damaged plastic parts.
RX
Battery
Switch (perhaps a bit intermittent will replace)
Tyres in slightly used condition, still nipply

See photo.

So I'm thinking about buying a new Marder Race and transferring the radio gear from first car into the new one. Considering a new 260 engine is 300 Euros, and does not come with gearing/clutch etc (The older Marder has the old GZ22 23cc engine, so will probably need new engine mounts as well) A new Marder is about 780 Euros which of course has the engine, clutch gears plus the rest of the car. Then use the old car for spares. Then buy battery checker and fail safe (missing on knackered one)

So probably the best idea?

Get your marder running AND buy the RACE these things are much more fun when there is more than one going around. use the RACE yourself and let your friends run the marder.


That's what I did


and you would have more chance of selling a going concern than a "basket case"

Sometimes difficult to start compared to other Marder (even with choke on, usual priming)
Goes fast initially, but then bogs down after a few minutes to a moderate jogging speed.
It does rev.

I've had a couple of experienced people look at it, they're stumped. The carb is OK because I've had a FWO Marder and swapped them over, it's still slow. It's got plenty of compression. With the other Marder runs fine, reliable engine. Brother is experienced in glo and petrol engines and can't figure it out either. Changed sparks, checked fuel lines etc.

The gears are off because swapping gearing ratio at the time. I know I can buy a big bore kit and basically it's a new engine. But I'm worried if it's exactly the same I'll have wasted my money.

Of course usual adjustments on carb to get correct setting, but to no avail..still unreliable.

I guess if someone has a FWO second hand engine I might be interested, has to be the same model though pretty sure GZ22 (save on buying more parts) must be cheap.

since you swaped carbys and same symptoms can you try swaping your coil over and test that. The coil may be breaking down as it gets hot.

now this is rare so don't get your hopes too high

I am trying to help this guy get his engine problems sorted. That's where it is going and what it's about.

Who is the spy?

I have a solution for your problem!! Well, it helped me with friends old Marder.
Take the engine out, separate the carb (unscrew from engine), and then take apart everything on the carb including choke & H & L needles/screws, but remember where all the screws & gaskets came from.
Now you need to buy a good carb cleaner (can use valvoline, silcolene or what ever you get) and clean it few times, especially hig & low speed needles/screws and all those holes, and spray inside those small holes where the gas goes in (next to choke) and out (opposite to the primer button).
Put all together, watch for gaskets to seat ok, put needles to factory settings (usually H needle 1.5 turns from closed & L needle 1.25 or better 1.5 turns), prime the fuel to the carb, choke it until it starts audible, open choke and pull.
That should do the job, and hope you'll be driving with big smile.

Did that Stegy (gave it a good cleaning and squirt of carb unblocker) changed the carb from the other Marder does not improve it.

Marder A runs well
Marder B is a lemon

Put carb from A into B, still slow.

You can get an SiKK(CY) 27cc engine with clutch and carb for US$ 169 http://www.davesmotors.com/store/product1506.html
If you already have a carb, then you save US$ 20

Shipping to the UK with USPS Parcel Post Air should be around US$ 41 (8 pds)

Plastic engine mounts is less than € 30 for both.

Looks interesting, thanks. But I think I'll go for a whole new Buggy. Sell off body and shocks to partially help pay it off, keep other parts as spares. btw as for that engine customs ontop of that (17.5% VAT and 4% Customs) plus Parcel Force fee £10. The $41 shipping is £22.

So in total £144 ($260 US)

Default RE: Repair or buy new Marder?

Just removed radio gear. Steering servos are two hitec HS-705MG, steering/throttle servo is hitec HS-615MG. RX hitec rcd HFS-04MI+ N
Nice weather is coming up (eventually) so want to the new one up and running. At least I don't have to buy radio gear, that saves almost £200. Are these servos "good" enough?

http://www.rcuniverse.com/product_gu...fm?servo_id=80


615..
(107 oz/in, .18 sec, 1.6" x 0.8" x 1.5", 2.1 oz, Dual BB)

705..
- Bearings: Single Ball | Oilite Busing
- Gears: Metal
- 60° speed: .26 sec @ 4.8v
- 60° speed: .20 sec @ 6.0v
- Torque: 161.00 oz/in @ 4.8v
- Torque: 201.00 oz/in @ 6.0v
- 2.30 x 1.10 x 2.00 inches
- 4.70 ounces


Actually flipping and flopping between Marder, Leopard (since it comes with tuned pipe) Monster Beetle Pro or Truck (better for wilder terrain)....

If I had the money one of each type, and even the same model twice (road and off-road tyres) to save changing them over all the time

Another thing that the Leopard Race comes with in addition to the Tuned pipe is a "basic" Alloy rear diff. (unadjustable, not selflocking)
