It is made by carson the 23cc pt engine and smartech just put there name on , Rc online de use it in a cheaper version marder now ! But only in the cheap one , its also in all the carson touring cars . Your right mate its a three bolt with no upgrades but you can get heads and rings &stuff but its not worth it as you can buy a cy or zenoah off eBay for less than a repair , I have the smartech spider and I'm just gonna rally that we engine until I get an engine ready to replace it but you need the gear carriers , gears , lay shaft , and engine mounts as the pt engine is different in those areas .
 
Smartech

Hi mate did you fit your kill switch ? If so !
Wasn't your engine running sweet before then ? Remember you couldn't get your engine cover off ? How did you go with that ? Did you link it to a third channel ? If so make sure you haven't killed it with 3rd channel and forgot to turn your kill switch off again ! Check your install , and see if it will start with the kill switch removed completely !
I am awaiting email from the manufacturer of the 28cc and 23cc pt engine carb factory settings so we can put them up for everyone's benifit they usually don't take long I will post them for all to see as soon as I can !
Cheers
Rob
 
Smartech spider 23cc and smartech UNO 28cc pt engine

Hi mate just received this email from hobbythek in Germany
Dear Robert,

the serial setting of the H and L needle is one turn open. But we recommend to start the engine, then open the throttle a little bit and adjust the needle by ear. The serial setting often has to be adjusted, because the carburetors are hand-made and therefore every caburetor is slightly different.

The settings of the 23 and 28cc engines are the nearly same.

Should you have any further questions, please don’t hesitate to contact us.
We look forward to hearing from you.


Best regards

Hi mate did you get your UNO started ?
 
Spider

Just checked my spider needle screws I didn't have any probs before with them but I just checked and I've been running both my needles at 1 and a eighth out each you'll notice when you screw both in fully that the high speed needle sits horizontal and low speed vertical ! I do play with my low speed now and then but maybe like hobbytheck says they need a tweak now and then as the carbs are all hand made . Doesn't sound good for the smt carb tho in my mind as it sort of suggests they don't hold a tune very well but I've enjoyed my little pt engine and that's all that matters for a lot of people !
Did you get the UNO going mate ?
Rob

Hi mate !
Wasn't your car going ok before you tryed to fit your kill switch ?
Did you put in a new spark plug ? Check your air filter , carb and exhaust to see if everything is tight ! Set your needles as per the email I got from hobbytheck ! I done it on my spider and one screw open on each needle starts my spider so they must be right but , can you tell us if you fitted your kill switch and was the car running before hand and sorry for saying mate !
Could you start a new thread on your problem as this thread is for tuning information and its getting blocked up by us !
Cheers
Rob

I'm not sure what you mean?Regarding the "people need to find your posts"
 
ok
i install the fail safe and clean the stop engine connectors
tray to start the engine -no spark i replace with new the same?
What could be?
 
The stock black fuel line can cause air bubbles to enter the carb. messing up your tune. Use the tygon (yellow/clear) fuel line to save yourself some headaches. 3/16 OD. for inlet and 1/8 OD. for overflow return line. Most small engine shops have this as chainsaws use it everywhere. Made a world of difference on my Losi 5ive T.
 
For performance tuning you should have the proper distributor wrench, accurate timing light, vacuum gauge, stop watch, fuel-pressure gauge, spare jets and power valves (if using a carburetor), spark plug reader, fresh spark plugs, and the necessary hand tools.
