i have an 88 samurai with the 1600cc bottom block and a 1300cc head running a torque cam and a webber carb altogether it gives me just under 100 hp
i am getting horrible gas millage but i think thats the cam
on cold days 30 +- after the choak cuts off the motor starts missing runs horrible no power, back fires and carb pops, it dies every time the motor drops under 1000rpm.
i maid a mock up preheater and it solved all the problems.
does any one have any ideas on other solutions or causes
