this is my first 1/8 engine so bear with me on what might be some "noob" type questions . . .

first - I got this off ebay and I'm wondering where can I get parts for this engine off the internet ? I want some head shims and the venturi set (7 mm, 8mm, 9mm). Who carries stuff like that on the net ?

second - I want some head shims for it and I'm wondering if any .21 shims will work ? Are all .21's the same size (I get that there are differences in thickness but I mean diameter) ? Will nova shims work on a picco engine ?

third - I pulled the glow plug out of it and noticed that there wasn't a washer between the plug and the motor. Is this right ?

fourth - not one word in the manual about glow plug recommendations. will be using the engine in primarily humid and hot Florida, if that makes any difference. Suggestions ?

thanks in advance

Mike
