they stopped putting 2 strokes on mowers in 2003 because of emissions.
now they make plastic junk I have a few lawnboys I have overhauled and use but parts are neither cheap or easy to get when it comes to some things.

That's one thing I am pretty much stocked up on is Lawn Boy D series "brick top" mowers and parts . Run forever with proper maintanance :D

you better on the CDI ignition modules they have recently discontinued producing them. I got three spare modules for mine
its a D-600 from 1974
 
Later version of the D series Jakewells but a good one too and looks to be in nice shape . The F series are decent machines too , Toro bought them out a bit later and things went down hill .
The brick tops I run are from the later 60's into the 70's although the earlier C series was a great machine too . LB did have some issues with the SS ignition modules and some of the plastic carbs were a pain .

mine is a mag deck OMC made in Lincoln Nebraska mine has the metal carb and I ususally burn the evirude / Johnson brand outboard oil in it and it seems to like it other than a slightly oily muffler. im up to try 40 or 50:1 since these engines are slow , simple , and over engineered
 
This is HP2 @ 40:1

so it sounds like the best way to get systemic toxicity is to breathe in the fumes of products containing PIB based additives

See below... so looks like you are fcked but don't know it til 24-72hrs later LOL

0.4.3 INHALATION EXPOSURE
A) DECONTAMINATION -
1) INHALATION: Move patient to fresh air. Monitor for
respiratory distress. If cough or difficulty breathing
develops, evaluate for respiratory tract irritation,
bronchitis, or pneumonitis. Administer oxygen and
assist ventilation as required. Treat bronchospasm with
an inhaled beta2-adrenergic agonist. Consider systemic
corticosteroids in patients with significant
bronchospasm.
B) IRRITATION -
1) Respiratory tract irritation, if severe, can progress
to pulmonary edema which may be delayed in onset up to
24 to 72 hours after exposure in some cases.

C) ACUTE LUNG INJURY -
1) ACUTE LUNG INJURY: Maintain ventilation and oxygenation
and evaluate with frequent arterial blood gases and/or
pulse oximetry monitoring. Early use of PEEP and
mechanical ventilation may be needed.
D) BRONCHOSPASM -
1) If bronchospasm and wheezing occur, consider treatment
with inhaled sympathomimetic agents.
E) OBSERVATION CRITERIA -
1) Carefully observe patients with inhalation exposure for
the development of any systemic signs or symptoms and
administer symptomatic treatment as necessary.
2) Patients symptomatic following exposure should be
observed in a controlled setting until all signs and
symptoms have fully resolved.

I see motul 800 has warning about allergic reactions regarding Calcium sulfonate

so gogglin "Calcium Sulfonate Health" i came up with...

looks 10x better than what is said about PIB. I mean none of this sh*t is good for you. It's just a question of if X is THAT much worse for you than Y.

Running 20:1 could be a Darwinian method of emission control! LOL just a decade or more too late for effective birth control.
