Hey, Have you had a chance to go on Amazon Prime and get a compression tester and check the engine compression after it is warm? (Do what you can to help it keep running for 10mins hot) then switch it off. Both spark plugs out. Put the compression tool inside front engine (with a metal rod) , forget flexi hoses. use a straight metal type that comes with the compression kit. Crank the engine full throttle for 5 seconds max. Read the compression Then repeat with the rear engine. Tell us what the engines say front and rear If we can start with the engine first , then we can move on to the carb , air system , fuel system , electric system. Bit by bit. Keep us posted!
will do thank you for your help I’ll be replying as soon as I can
