ok will check in to excel ch ignition.. would you recommend having the heads drilled out and retap for 14mm. or use the 1/4 20 small plugs which are 12 dollars each.. little expensive.
if i change it over i know i can use gas and would probably be sure of not dropping a cyl when ruining..
any help would be appreciated..
tks al
Why go to expense of drilling and threading the heads to put in a heavy sparkplug and add additional weight of an EI?
True...you do not need to install the bigger spark plugs, but when running a twin cylinder electronic, ignition is not like glow. With glow a dead cylinder can happen. With spark ignition a dead cylinder (and maybe a crash) should never happen. Capt,n
