Hi guys I have an weedeater featherlite petrol trimmer 18cc and the pole is damaged and I kept the engine and thinking possible to convert into a petrol engine for my large spitfire it has a primer bulb the engine runs fine. my questions are is it is acceptable to use it as an engine when it has a primer bulb??

and since it is 18cc has it got enough power for (xmas Build Project) for 2011 year spitfire wingspan 89inch roughly 30-35lbs weight ? I can't work out the weight to power ratio i am too thick! hehe thanks guys

18cc is way underpowered for a 89" spit, I would be looking for a 50cc engine.

oh right that big then right let see if I can nick the moped bike that lad got across the road!!! thanks for the advice it is my first time with lma etc let say in cu i have 4 stroke 90 cu it that equal to roughly 1cc ?? so it looks like I need zeaoah engine then wooh mega deep pocket then mm i am going to have a serious thinking business!! cheers

a .90 4st glow engine is roughtly 15cc but the power delivery is different to a 15cc petrol engine

One word ......NO.

Agree with Matt here, I had the DB Hurricane at 88" span with a Zenoah 38cc. That was Adequate but no way would I go smaller.
