Hi All,
Newbie to this forum and a returner after 15 years to RC.
I have a "new to me" Thunder Tiger S50 (uk if that makes a difference) which is next to new and still needs to finish breaking in but I cannot get it to run at all under it's own steam.
Story so far (apologies for going to much into it).
Will run at first prime then dies after fuel runs out in carb (i'm assuming).
Removed fuel primer bulb from the circuit. Attached new line and spun motor over with finger over exhaust - she primes just fine.
Started it and runs then dies after after a few seconds as with the primer bulb installed. You can see bubbles going backwards if that helps but may be just where it just died?
When I put the primer bulb back in she will carry running if I squeeze the primer bulb bit by bit (almost like a fuel pump.
I would assume a vacuum issue but it primes fine with finger over exhaust.
I have bought a new carb and reset to factory settings thinking it could be the carb. Exact same thing.
Loads of compression. Sounds great when manually priming once running?
Confusing the hell out of me.
Any help more than appreciated.
Pic of how it is put back to factory as i got it!
