By simple maths I'd expect the fuel consumption to roughly half at half the revs. My outfit with nobody in it weighs in at @750 kilos so with my 18 stone plus the wife & three kids we're a fair weight.
Have you had it into a GOOD service establishment to have it looked over ?

Went in dave crawfords at lymington for a service but due to one of the voltage regulators bursting into flames it only got a fuel pump rebuild and regulators changed.
They said it looked so clean that they reckoned the carbs were nice and clean.

Keep meaning when I got out to put the quicksilver quikleen through it by adding to fuel but keep forgetting.

May "look clean" but have they been set up and balanced?

Compressions all even?

There'll be a way to make it run leaner by adjustment on the carbs but I've no idea how to advise you to do that.

Sorry.

Take the six drain drain screws out the bottom of the carbs one at a time and check that a main jet has not fallen out one of them. Punctured float? Dickie needle valve? Fuel pump diaphram?

Compression on 6 cylinders were all around 120psi carbs look all to be running good but not had them cleaned thoroughly yet.

Here's a short video of the trip on Sunday I just video'ed the engine while running to check if the engine height was good it looks reasonable nice and clean out the back end

Had a few issues with mine until it took a battering on the beach which seemed to shake the crap about in the carbs and it flew afterwards and that has given me the excuse to clean them. I drained them initially & it didn't help.

Any good tips on how to make sure I do it right?

I hope this isn't a thread hijack...

Just watched a 3 part youtube of a guy stripping down V6 carbs. Is it necessary to do a complete strip or will removing the float bowl and giving it a good blow with the airline do ?
