Kdheath,...

Thank you very much for the help and advice. Yes,... I checked out Tower's web site and noticed the Venturi and Neddle Assembly for the .10 STD engine. It came out to less than $20 (including the shipping) so I ordered those items. I figured I'd try the venturi and needle assembly to see if it works. If not I'll take your suggestion and just wire the carb. open.

Just wondering,... are C/L engines setup with different timing?? If so,... would ordering the piston and sleave for the .10 STD help to truly convert this R/C .10 into a Stunt .10??

Thanks a million for all the help and contact info.

Sincerely,
Steve T.
