Briggs Flathead / searching for a carburetor with oil injectors and accelerator pump.
« on: November 01, 2021, 05:58:56 pm »
hello,

does anyone know of a carburetor that has an accelerator pump and oil injectors?
anything from 3/4-2 inches internal throat diameter will work.

Briggs Flathead / opposed twin briggs engine crank differences
« on: November 01, 2021, 05:34:47 pm »
im currently obsessed with these briggs engines.

i know there's two 46ci engines one with a longer stroke and one with a large bore (super rare, i wish i had one)

and then there's 40 and 42 ci engines as well.

my question is are the crankshaft ends where they sit in the block and pan (bottom half of crankcase that unbolts)  the same, could they be placed in any opposed twin engines, if not which ones will fit which.

my second question is if anyone has a few cranks on hand, what are the throw offsets (distance between center nose and crank shaft pins (where the connecting rods connect.)

thanks,

can a non pressure lube opposed twin be converted to a pressure lube engine?

also i recall some one installing a special switch that acted as a relay and wouldnt let an engine start until the oil pressure/level? was high enough. what is that switch called?

Briggs Flathead / simple modifications to increase power of engine.
« on: February 06, 2021, 04:56:28 pm »
i have heard that a few engines are the same except for the addition  of restriction on the intake, carburetor and  or exhaust. is this true and are there any simple mods that increase the performance of opposed twins. as an example i remember reading somewhere that a 16hp and 21.5 hp engine was the same except for an additional plate in the carburetor that reduced airflow.

Briggs Flathead / what parts are cross compatible with other briggs opposed twin cylinder engines?
« on: February 06, 2021, 04:51:57 pm »
hello,

i was wondering what parts such as cylinder heads, pistons, rings, cam shafts, cranks and connecting rods are cross compatible between briggs and stratton opposed twin engines. i have heard some connecting rods and pistons will fit into like 5 different engines.

any information is much appreciated.

thanks,
