Cox .049 Sure Start Muffler and Carb Running

I finished everything on the engine except the throttle response sucks. The muffler works great higher rpms and much quieter than before. Last time i tested the muffler kept falling off so i had to put a screw to hold it in and jb weld to seal. The other screw thats sticking out on the right side is to hold the muffler up and from turning sideways.

Bad throttle response maybe due to timing

@journeyquest1 no its because its not a carb, its a choke thats why it doesn't work so well but i modded a REAL carb on the back plate with jb weld and its revs like a f1 car. its so amazing but i don't really feel like making a video unless people request more of the updated version also i shortend the tube from the collector to the muffler also made the port bigger for more power

have you figured out why the throttle response sucks? i tried doing the EXACT same thing a few years ago and the throttle response almost was random. aka no throttle response.

@thegenrl i found a carb for these and modded it, it has like F1 engine throttle response and its amazing also improved on the muffler too. Going to make a vid of it soon.

[superbungabunga]

this engine seems to eat fuel up very quickly

[mannexx111]

sos wow I didnt realize you could do such great things with the small o49 the muffler of yours is amazing

[MrAdamseye]

That throttle response problems seems like it was just loading up with fuel and could not burn it off fast enough. In other words was running to rich.
