Old Briggs 18HP Ignition Module Help

[smallercrawler]

Hi all, was wondering if someone could help me with older Briggs engine bought from Northern Tool back around 1990. Engine is repower in Terramite backhoe, has run fine for many years. Recently tractor started running in fits and starts, was harder to start, low power. No problems in fuel system. Finally quit starting at all, cranks fine, just no/very weak fire at plugs, (battery is good). Think it is electronic ignition module. Problem: only data on engine is 18HP IC-family number: SBS694U1G2RB:EM; Model #: 42H; pressure lube; cast iron sleeves. Cannot find any data on this unit at Briggs/jack's/etc. websites to get module #, (appears to be obsolete numbering system). Any help please on ignition module no.?
(Tractor is kind of like me: too good to scrap, not worth putting much money in)! Thanks for help.

Give B&S a call at 1-800-444-7774 to see if they have a P/N for the ignition module and if is still available. You will need all those numbers you have posted. Hal

Twin cylinder flathead? Should be 394891

check ebay maybe

ANON is correct. That is the number for the magneto armature my B&S dealer sold me for my 18hp twin about 2 years ago for @ $50. Those numbers look to me like Northern sells reman engines. I think that number which starts with SB means short block.

I agree with jerry,mod# appears to be a short block,I would suspect same is an eng that was builtup from a basic short block for 18hp by briggs to match spec's provided by tractor/equip mfg & assigned a special number,due to mfg overruns,equip mfg design change's or mfg going out of business/couldn't pay for contract quanity of eng,these units were offered by briggs as surplus & northern probably bought some/all of same,I've had same experience with northern over the past 10 yrs with strange mod# with 4 tecumseh & 1 briggs,only way I could lookup parts was backtrack short block pn to cross ref to eng mod#.

First thanks to all who replied, ANON is indeed correct 394891 is the number, however dealer tells me it has been replaced by 440441. Either way I will have one in the morning. I now understand why the numbers weren't adding up. Again, thanks to ANON and all for the quick help.

Your welcome, and the number you were given is for a Sten's replacement which will work fine.
