11HP Clone

OK after spending many hours reading about the throttle cable hook up I've decided the best way to do it would be to remove the governer and use those parts to do it. Before I do that I would like to upgrade the valve springs. What are the upgraded springs for the gx340? What does it currently have in it? I know everyone says to replace the flywheel first but will it be safe to run without doing that right now? Already have too much money into this project.

Just take the govenor off. Don't replace the valve springs.

Is it true even with the govenor off it will only rev to 4300? I keep reading conflicting arguments about taking the govenor off and damaging the engine. I would like to get this right the first time and not ruin any engines.

Odds are you won't blow the engine under 5000.

If you install stiffer springs you must upgrade the flywheel for safety reasons, a billet rod isn't a bad idea either.

Ok so if I just remove govener, add air filter and exhaust how much gain do you think I will get? Also what is the best way to oil the UNI filters? I have a K & N in my Mustang and thats a PITA to clean and oil. Any tips would be helpful.

I would also advance the timing 5 deg. You may get a horse or 2, but you are also getting close to 5000 compared to 3600, so you are going to go faster.

Uni filter, wash in cold soapy water, rinse, dry, apply whatever heavy oil you have lying around(anything from 2 stroke oil to gear lube will be fine, just nothing with solvents like WD-40 or 3-in-1) squeeze oil into filter until its saturated, squeeze in rag to remove excess, use.
