I am sure you have seen this kind of post before and I have been searching everywhere to try and find something different than the usual troubleshooting as that hasn't fixed the issue I have.
My boy got a hyper 7. Its a .21 3Port but it just wont start at all. We have had it in 2 different shops, neither could sort it. The engine just wont fire. It will prime fine and plug and starter fine, tried giving a bit of fuel direct still wont fire. Last shop we had it in suggested the compression was ok so I have not gone down the replacement sleeve/piston yet. We did find what looked like the smallest of air leaks maybe at the pinch bolt so we sealed it, and everywhere else while we had it off but still no go. All needles are good, just wont fire
My boy wants to just convert to electric but I want a working nitro in the house hehe. Can anyone suggest anything else i might be able to try. Piston/Sleeve quite expensive dont want to replace that unless 100% it would fix it.
TIA
