Well

I got this idea

if air is thicker when warm

then it will find it harder to escape from the cylinders??? thus rising the
compression ??? so i drilled 2 holes in the inlet manifold directly between every 2 inlet holes in the head

so every 2 cylinders gets the same amount of "hot" air

the plugs i got off an old daihatsu 4x4, fitted nice in the holes after threading them

then i got a wire from the heat switch to the plugs and gave it a try

and it worked

not perfect but 2 times better than no heat

DONT!!! use easy start with this contraption!!!!!!

or the air cleaner will have flames coming through it


the proper way is to take the head to an enginneer to drill holes in it

and fit them like on diesel cars

you can use the "silly-massey" thermostat pre heater but its useless69) it has the same idea as my contraption

but 10 times more complicated

nice to see another welsh man on this site

i was getting loneley

. why am i typeing in iaith y sais????
