Currently sat on the boat after about the 5th test trying to find out why the boat keeps bogging down and stalling!
So the carbs have been stripped and cleaned after each test and mixtures reset.
Have put completely fresh fuel and oil in.
Cleaned all fuel lines.
Has a new fuel tank and line and inline filter.
New spark plugs.
The engine runs sweet on muffs and at low speeds. Then will go at full speed for around 1 minute then revs will drop and it'll stall.
Couple of pulls with choke on and it starts at straight away!
It will sometimes not gain revs again until you fiddle with the choke abit.
Doesn't miss fire at all just cuts out which suggests fuel but have done everything to do with the fuel system!
Loosing patience!!! Help please!!
