hi, i need a new plug for my mach .28. all i can get my hands on at the moment is os8, osA5, and osA3 plugs. will any of these be ok, if not what is the best plug to use. thanks

th os 8 will work its shorter then a regular plug but it will still work

ok cool, i got the a5 but it only lasted 1/2 a tank b4 it **** itself

Do your self a favor and get the correct plug a standard long plug!

are you asking about the macstar 28? If this is the engine your asking about it is actually a picco long plug w/ no idle bar. Forget the part #.

yes thats the engine im talking about

ive used a'3s and 8's in mach 28's for a whole season with no problems

Never said they OS plugs would not work they just are not the correct plug. Have you tried the correct plugs to see how they work?

i know what yew mean, and i know yewr right, but the engines are terrible so i didnt bother lmao
