im looking for a briggs opposed twin 46ci big bore or long stroke block that is fully pressure lubed or a 42ci wich is fully pressure lubed.
budget is relatively small, i saw sears sell the a 46ci block for 600 (when it was  in stock/production) for 600, well my budget is a around 50% of that for a single block. i know there rare, we could work a trade...

thanks

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,

oh, i wouldnt machining them myself. i would have someone else do it after i designed them, however the weather heres cold and i dont have a heated garage... yet. but yeah good point i could just go and measure it myself...haha

8
bore size, depth,  outside dimensions of the heads, i was considering to custom machine a new head.

9
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.

how does one disable/remove entirely the rpm governor of  a briggs and stratton twin 2 opposed twin.

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,

hello i was wondering if anyone knew a place i could find the dimensions of  Briggs and Stratton parts for the opposed twin series of engines. i have heard you people on this forum are experts on these engines.

thanks,
