hi skip, you mean the starting the engine ? yes ?---- ( not starting the all Race ? ) until now, with this 50 years ( and more ) old piston , it was not evan necessary to use the valve lifter to kick it over.

500 to 650 doesn't sound much, but it is a 30% increase. Are you doing anything to the head/carb? What about the transmission, will it be able to handle all that additional power? well, now, with this more than 50 years old piston it should bring 40 ore 42 HP, - this in best condition. as it is con...

What break fluid are you using in it? hi skip, I do use the same oil as in the engine, a straight 50 mineral. Is it the hose or the slave cylinder causing the problem guess it is the hose and the according connectors. so I get air in the slave cylinder..... if you use proven hydraulic parts from mo...
