Title: Re: 8 mm deep socket in 3/8" drive for M90 Hit & Miss engine
Post by: IndianaRog on August 23, 2019, 08:34:10 pm

I found the socket fits the M91 plug when plug is out of the engine...but barely fits due to touching other metallic parts of the head...might grind the socket's exterior down a bit to try for a better fit.

ps...Amazon pricing is kind of amazing...sometimes it goes up or down for reasons unknown...glad I grabbed one at the low point

I saw a post by Gil regarding the size of the socket needed to remove the spark plug of one of Jin Machine's M90 hit and miss engines.  Since I did not have that socket and figure eventually I will want to remove the spark plug...I ordered one off Amazon for the princely sum of $3.44 USD including free one day shipping.  It arrived today and fits perfectly.

How can you beat that price vs. breaking the plug using an ill fitting wrench?

Price has gone up with Amazon Dynamic Pricing as a result of others ordering. Now $7.98. 🤮

Yes - same plug.  They are identical.

Does this also fit the plug on the M91?

Ironically, I used that socket today to clean a fouled plug...works like a charm!  AND, engine roared to life again after the cleaning.

I actually have a metric set of 1/4inch drive deepwells but I am thinking my glow plug wrench I used on the rc helis may work when I change a plug.

You'll never regret having that tool at the ready.
