If you had a cordless drill or dremil with variable speed ajustment and put a rubber sanding arbor in the chuck and just ran it against the flywheel it would make easy work for starting .....just a thought .........amazing how those wee engines work
I specialise in these and other pre-built model engineering. These are well built but changing the governor spring to a bic lighter spring will get you a much better display hit and miss. Other tweaks on my channel. The one to get now is the excellent Retrol / MUSA HM-01. Chinese models at the best are the equal or superior to Western models now
So if its firing every stroke at low RPMs, its a 2 stroke? I noticed the exhaust closing at low RPMs, and staying open at hi RPMs, as it should. But no movement of the intake. And theres no ports at the bottom of the cylinder? 🤔
@UK-CB-RADIO you mean a 2 stroke. Without a cam, the exhaust valve would either open every rotation or stay closed every rotation, except for when it opens to keep from over reving. But I dont see any room for ports on the sides of the cylinder, so. I dunno. The manufacturer says its a 4 stroke, but Chinese manufactures will say anything.
I made a rubber wheel with a shaft to put in a drill. Very handy for starting small engines with the big flywheels.
Well done fred that is a interesting engine
Nice one Fred!
that's a great little model fred thanks for that 👍👍
Sweet sounding little engine

Chuck up a skateboard wheel,or a rubber scuff eraser.
Dremel is too fast with too little torque. Use a cordless power drill.
A masterclass in fault isolation.
. Good job on the engine. Steam train 🚂 😊

Thanks for the info. I normally try to get them to run as slow as i can.
Hi Fred What's the exhaust valve clearance supposed to be looks quite a lot. Enjoyed the video
Hi Iam not sure but it does have a wide gap.
Hey Fred. Ru going to hamfest on Friday. I'm thinking of driving up.

Hi. No working bud :-(
Hey got a question about the old mamon roadster. I have one what oil can I use to lubricate it? I don’t have any special oils on hand
just normal.
I just use 10w engine oil.
So if its firing every stroke at low RPMs, its a 2 stroke? I noticed the exhaust closing at low RPMs, and staying open at hi RPMs, as it should. But no movement of the intake. And theres no ports at the bottom of the cylinder? 🤔
Yes that makes sense. It must be 4 stroke.

Good enough to refund the engine ? when its a legal requirement to refund something that is faulty.
Its just that DIYengine are an honourable company. A credit to them.
Thanks for the comments. I love playing with these little engines as well as steam models.
