Will have another look, thanks 

Also when the exhaust is disconnected from the port, the compression is still high just in case anyone thinks the exhaust is blocked!

Yeah I give it a good clean, it’s like new, the cylinder head and piston. Carb was rebuilt with a genuine walbro kit, new piston rings, new gaskets all round, and still, high compression. It’s in the cylinder sleeve because when the head is of it moves freely, but when I put the head and spark plug on it gets really hard to turn over 🥲

I can’t see one, I had the head off etc, the exhaust port is clear along with the other ports within the head

Hi, having high compression issues with my 172 Marco engine on the voloution 2, I had the carb rebuilt, new rings, gaskets etc, as soon as I put the cylinder head on and the spark plug in, it becomes hard to turn over, like really hard! Even when the carb is completely off and the Reed valves are out.

It seems like there is pressure is not getting out from the cylinder somewhere, the exhaust ports are all clear and the rings are fitted correctly.

If anyone has had a similar problem could you give me some advice please?

Hi guys,

I have been flying for 7+ years now, I’m applying for first mortgage in the next month, not part of any club or a BHPA member.

Can anyone give me some advice for the life insurance side of things, is it better to be affiliated with the BHPA or similar before applying?
