QuestionQUESTION: Eric
I have a Briggs model l126602 intech that is about 4 years old and used for personal use.
it has never started hot. I have changed the plug.
Someone said it may be valve lash? if so what should it be?
or is there a compression release on the engine that needs adjusting?
Thank You..........Les
ANSWER: Please re-send the engine model, type and code number. I can look up the valve clearance with the numbers.
Have you ever checked the head gasket or intake gaskets to see if they may be leaking?
Let me know.

QUESTION: Eric.
Thanks for the reply.
Here is the data for the engine.
Model 126602
Type 0113E1
Code 010328Ea
As far as the intake gasket goes I put a kit in the carb within the last 30 days and I tested all the head bolts for tightness.
It starts on the first pull when cold (4 pushes on the primer)but will not restart after it has warmed up.
Also I set the air gap to .006 on the mag.
Thanks again..............Les
PS which shop manual do you recommend?
AnswerI would recommend the Briggs manual part number 272147.
Both valve clearances should be set to .004-.006 inches. The compression release is not adjustable.
To check the valve clearnace, rotate the engine to top-dead-center (TDC) on the compression stroke. Continue rotating the engine 1/4 inch past TDC on the compression stroke and check the clearance. You can use a WD-40 straw or drinking straw inserted through the spark plug hole to find TDC and 1/4 inch past TDC.
Let me know if this helps.
Eric
